Updated the minimum software versions in Table 3 for CSCvd86660.

Introduction

Cisco UCS Manager provides unified, embedded management of all software and hardware components of the Cisco Unified Computing System (Cisco UCS) across multiple chassis, rack servers, and thousands of virtual machines. Cisco UCS Manager manages Cisco UCS as a single entity through an intuitive GUI, a command-line interface (CLI), or an XML API for comprehensive access to all Cisco UCS Manager functions.

System Requirements

To use Cisco UCS Manager, your computer must meet or exceed the following minimum system requirements:

- The Cisco UCS Manager GUI is a Java-based application that requires Sun JRE 1.6 or later releases.

- Cisco UCS Manager uses web start and supports the following web browsers:

– Microsoft Internet Explorer 9.0 or later

– Mozilla Firefox 7.0 or later

– Google Chrome 14.0 or later

Adobe Flash Player 10 or higher is required for some features

- Cisco UCS Manager is supported on the following operating systems:

– Microsoft Windows 7 with a minimum of 4.0 GB memory

– Red Hat Enterprise Linux 5.0 or higher with a minimum of 4.0 GB memory

Updating Cisco UCS Releases

Starting with Software Release 2.1, the Cisco UCS Manager A bundle software (Cisco UCS Manager, Cisco NX-OS, IOM firmware) can be mixed with the previous release’s B or C bundles on the servers (host firmware (FW), BIOS, CIMC, adapter FW and drivers).

Table 2 lists the mixed A, B, and C bundle versions that are supported:

Note • If upgrading from a pre-2.1(2a) release and running Management Firmware Pack, refer to caveat CSCud81176.

- If an environment includes a mix of servers, refer to CSCuh61202 and CSCus64439 for caveat information.

Note To avoid this issue, first upgrade any Cisco UCS 1240, Cisco UCS 1280, and Cisco M81KR adapter firmware before updating the Cisco UCS infrastructure components—Cisco UCS Manager, IOM, and FI.

- A mix of servers running different B-bundles may be run with a single A-bundle. However, any given server must be running the entire B/C-bundles (with associated drivers), so mixing the 2.0(3a)B BIOS with the 2.0(4b)B CIMC on a server is not supported.

- The OS hardware and software interoperability is relative to the B/C-bundle on any given server. To see what OS is supported, see the Hardware and Software Interoperability documentation associated with the B-bundle version.

- The A-bundle version must be at or above the same version(s) of any B/C-bundles running on the servers (see Table 2 ). This applies for patch levels as well, even though they are not displayed on the table. For example, you can mix 2.1(1f)A with 2.1(1b)B, but you cannot mix 2.1(1b)A with 2.1(1f)B.

- Some features introduced in Cisco UCS Release 2.1 require that both the A-bundle version and the B/C-bundle versions be upgraded to the same version. For example, the lower power budget supported for Cisco UCS Release 2.1 is not supported for servers using 2.0 firmware.

The following Cisco UCS Manager 2.1(2x) features are exceptions:

- CIMC session management

- Windows 2012 NPIV support

- ESX/Linux fNIC driver enhancements

- Cisco VIC PXE boot optimization

- FlexFlash (SD card) enablement support

- Transportable Flash Module (TFM) support

- M3 board programmable firmware upgrade

The CIMC firmware version that initially shipped on the Cisco UCS B200 M3 and Cisco UCS B22 M3 blade servers does not support the Cisco UCS Manager feature for updating a board controller. For Cisco UCS Manager to be able to update the board controller on these blade servers, you must upgrade the CIMC firmware to 2.1(2a).

The following Cisco UCS Manager 2.1(1x) features are exceptions:

- Single root I/O virtualization

- Power capping

- C-series single wire management

For detailed instructions for updating the Cisco UCS software and firmware, see the appropriate Upgrading Cisco UCS document for your installation.

Hardware and Software Interoperability

For a complete list of hardware and software interdependencies, see the Hardware and Software Interoperability for UCSM Managed Servers for a specific Cisco UCS Manager release, here:

http://www.cisco.com/c/en/us/support/servers-unified-computing/unified-computing-system/products-technical-reference-list.html

Internal Dependencies

Table 3 shows interdependencies between the hardware and versions of Cisco UCS Manager. Server FRU items such as DIMMs are dependent on their server type, and chassis items such as fans and power supplies work with all versions of Cisco UCS Manager.

Default Zoning is Not Supported in Release 2.1(1a) and Later Releases

Default zoning has been deprecated from Cisco UCS, Release 2.1(1a) and later releases. Cisco has not supported default zoning in Cisco UCS since Cisco UCS, Release 1.4 in April 2011. Fibre Channel zoning, a more secure form of zoning, is available from Cisco UCS, Release 2.1(1a) and later releases. For more information about Fibre Channel zoning, see the Cisco UCS Manager configuration guides for the release to which you are planning to upgrade.

Caution All storage connectivity that relies on default zoning in your current configuration will be lost when you upgrade to Cisco UCS, Release 2.1(1a) or a later release. We recommend that you review the Fibre Channel zoning configuration documentation carefully to prepare your migration before you upgrade to Cisco UCS, Release 2.1(1a) or later releases. If you have any questions or need further assistance, contact Cisco TAC.

Load a kickstart image either from the bootflash or through tftp. If the drive is still accessible, copy the debug plugin to it and load it. If the drive is no longer accessible, run the 'init system' command to re-initialize the SSD.

If the drive is still accessible it may be

possible to repair the file system corruption from the Linux shell as follows:

- unmount all partitions, /dev/sda3 .. /dev/sda9. You might also have to unmount /dev/mtdblock3 prior to being able to unmount /dev/sda7.)

- run 'e2fsck -n -f /dev/sdaX' for X = {3, .., 9}

- Based on the number of errors, run 'e2fsck -y /dev/sdaX', X = {3, .., 9}, to attempt having the system repair the errors.It is recommended to copy critical data back to the SSD because data on disk could still be corrupted even after file system corruption has been fixed. Alternatively, you can run the init-system script to reinitialize the SSD.

Note This can take a while depending on the size of the drive.

When Cisco UCS C-Series servers are configured with the IPMI interface enabled, a vulnerability in the Cisco Integrated Management Controller (CIMC) on the Cisco Unified Computing System Series Platforms may allow an unauthenticated, remote attacker to obtain the password hashes residing on the affected device.

The vulnerability is due to the implementation of an insecure authentication protocol. An attacker may exploit this vulnerability by sending a crafted packet to the CIMC of an affected device. An exploit may allow the attacker to receive a response from the CIMC that contains an RKMP message that will allow an attacker to obtain the password hashes for the system, which can then be used in an offline cracking attack.

The syslog was not truncated after it reached the configured maximum size. It may fill up the Fabric Interconnect file system.

Use the following commands on the Fabric Interconnect to verify if the issue is due to this file:

connect nxos a (or connect nxos b)

show system internal flash | grep root

Immediate Workaround:

If the file is very large, esp. close to 100 MB, then:

From Admin / Faults, Events and Audit Log / Syslog, change the size of the local syslog file to be much smaller, such as 10000 KB (the size can be increased later).

Longer term workaround:

Ensure the severity for the local file is at critical.

If you still see a significant growth of the file even after the smaller file size specification with the steps above, you either will need to repeat the steps above or disable the syslog file entirely and use a remote destination.

Cisco UCS C220 and C240 servers running Cisco USM Manager Release 2.0(2) may experience a PCI bus number change when upgrading or downgrading the BIOS. This issue can cause the following:

- A storage controller update failure from Cisco UCS Manager when upgrading to Release 2.1.

- OS installations such as VMware might require manual intervention after bus number changes are seen.

To avoid the Cisco UCS Manager update issue either via the host firmware pack or through the firmware auto install, you should update to Release 2.0(3) before upgrading to Release 2.1.

If you have already upgraded to Release 2.1 and see an "Unable to find Storage Controller Device" error, reacknowledge the servers to fix the issue.

Note It might take up to 20 minutes for the failed firmware update attempt to timeout in Cisco UCS Manager before the server reacknowledge is started. The firmware update completes successfully during the reacknowledge task.
For a VMware installation, the PCI mapping has to be manually changed using the ESX console.

In a very rare case, Cisco UCS Manager failed to restart due to the same UUID being allocated to two different service profiles.

So far, this issue is seen only been observed for UUID pools and not for other ID's such as MAC addresses, WWXN , IP etc.

This could be a day-1 implementation flaw happening in rare conditions.

a) A static UUID is assigned to a service profile that is associated.

b) In the single transaction, delete the service profile and create a new service profile (with a different name) with the same UUID suffix and UUID Pool.

This step can be achieved only through importing (with replace option), XMLAPI, or CLI and modify the pool prefix.

The expected behavior is that the UUID is correctly assigned to the new service profile and the pools reflect that. In some cases, the pool shows the allocated address as unassigned.

c) Define a pool with the same UUID and create additional service profiles.

This step will lead to the same UUID to be potentially allocated to the newly created service profiles.

Avoid the condition where the same UUID can be released and then allocated in the same transaction. For example, do not delete a service profile with statically assigned IDs and then create the new service profile with the same static ID in one transaction. Also avoid importing with the replace option when the existing configuration and the configuration to be imported have overlapping IDs that are assigned to different service profiles.

If Cisco UCS Manager fails to restart, contact Cisco TAC for further assistance.

The Cisco UCS Manager DME process might core dump when creating large number of service profiles with a large number of vNICs and a large number of VLANs on each vNIC in a single operation.

On a Cisco 6200 Series FI, the Cisco UCS Manager DME process might core dump during the following large scale operations:

- Creating 300 service profiles with 32 static vNICs in each service profile and 50 VLANs on each vNIC.

- Creating 200 services profiles with 32 static vNICs in each service profile and 850 VLANs on each vNIC and then deleting all of the service profiles and repeating this process multiple times.

The same problem could happen on a Cisco 6100 FI with a similar or smaller scale.

A memory leak issue shows up when a very large number of MOs are committed in a single transaction. The same issue exists in previous releases (tested with Release 2.0[4b]) as well.

It has been verified that there is no memory growth with reduced numbers such as:

- Creating and then deleting 100 service profiles with two vNIC in each service profile and 100 VLANs on each vNIC.

- Creating and then deleting 20 service profiles with 32 vNICs in each service profile and 50 VLANs on each vNIC.

When creating large number (>100) service profiles with large number vnics (>16 ) and large number of vlans (>50) on each vnic, avoid using a single operation to create all the service profiles. Break it down into multiple operations with a smaller number (such as 20) of service profiles in each operation.

A global VLAN goes missing on an FI after rectifying a conflicting FCoE VLAN condition after upgrade from 1.4.1 to 2.0(4a) or later.

In releases 1.4 and prior a VLAN could be configured to be used both as regular Eth VLAN and as an FCoE VLAN. In the example illustrated in this defect VLAN 20 is both an FCoE VLAN for VSAN 20 and a global VLAN.

In 2.0 and later releases, this is an unsupported configuration. VLAN 20 cannot be both an FCoE VLAN and regular Eth VLAN. Accordingly faults are raised when system is upgraded from any pre-Release 2.0 release to Release 2.0 or later to bring attention to the VLAN misconfiguration.

Faults observed:

VLAN default is error-misconfigured because of conflicting vlan-id with an fcoe-vlan

VLAN20 is error-misconfigured because of conflicting vlan-id with an fcoe-vlan

To rectify this, user assigned a new VLAN (2020) as the FCoE VLAN for the VSAN. This triggers re-configuration of VLAN 20 and in the process, some times, VLAN 20 may get completely removed from NXOS configuration.

Due to this any host that is carrying VLAN20 will see a service outage

There are two options based on whether you want to retain the existing VSAN-VLAN assignment or retain the VLAN as global VLAN.

1) If the intent is to retain the VLAN as a global VLAN then after changing FCoE VLAN assignment, delete and re-create the missing VLAN (20 in the example). The VLAN will get correctly reconfigured on NXOS.

Or

2) If you want to retain the VLAN as an FCoE VLAN, then assign a different VLAN for the veths using it.

This error situation can only be reached through an upgrade workflow from a pre-2.0 release. In a 2.0 or later release, you are prevented from configuring a VLAN to be both FCoE and regular VLAN. So it is better to plan the re-assignment of VLANs as part of upgrade window downtime

The PCIe Address for the Cisco UCS M81KR Virtual Interface Card (VIC) is not seen in the GUI (or CLI). It causes no functional impact.

The only workaround is to boot some host OS onto the blade and then determine the PCI address and map it to the MAC address (and subsequently to the vNIC). In a 2.6 kernel based Linux for instance, the /sys/class/net/<device> directory has relevant information.

When a cluster configuration is set up such that I/O module 1 goes to fabric interconnect B and I/O module 2 goes to fabric interconnect A, then the Ethernet devices are given ports 1 and 0. However if the setup is straight, with I/O Module 1 connected to fabric interconnect A and I/O Module 2 to fabric interconnect B, then the devices are assigned ports 0 and 1.

Connect IOM1 to fabric-interconnect A, and IOM2 to fabric-interconnect B.

Sometimes FEX host facing ports are not created/discovered in Cisco UCS Manager at the end of chassis/server discovery. This results in Cisco UCS Manager assuming that the adapter has connectivity to only one fabric. So that blade server cannot be used to associate with a service profile which has vNICs that require both fabric or the fabric to which connectivity is not yet discovered. This happens very rarely during chassis and server discovery.

Re-acknowledge the server (or chassis) so that Cisco UCS Manager attempts discovery once again.

On platforms with 00B storage controller, Cisco UCS Manager displays usable (coerced) value in disk inventory section, which is different than the raw 'NumberOfBlocks' value displayed in catalog section.

This is a non-issue; Cisco UCS Manager is designed to report the coerced, or usable, size as reported by the LSI controller. Both the host and OOB interfaces report this same value.

CSCum16710

After downgrading the Cisco UCS Manager firmware from 2.2(x) to 2.1(x), any change to a service profile whose associated server has QLogic adapter(s) may trigger a server reboot.

This occurs when the host firmware package is enabled with the related adapter selected for the service profile. The affected servers include blade servers with the N20-AQ0102 adapter and rack servers with the UCSC-PCIE-QSFP adapter.

Before beginning the downgrade:

- Deselect the related adapter in the user-defined host firmware package.

- Check the default host firmware package and make the corresponding changes.

Cisco UCS Manager 2.1(1) is not supported with Cisco UCS Central 1.1(1). If you downgrade from Release 2.1(2) to Release 2.1(1), any artifacts, such as global service profiles, global policies, or VLAN/VSAN configurations, that were created on Cisco UCS Central remain in Cisco UCS Manager, but cannot be modified or deleted.

Unregister Cisco UCS Manager Release 2.1(2) from Cisco UCS Central before downgrading.

A server running ESX can only disable C1E when using the default BIOS policy. Once a new BIOS policy is created with C1E disabled from Cisco UCS Manager, ESX does not recognize C1E as disabled while the BIOS setup menu and C-state dump from EFI all show C1E is disabled in the BIOS policy from Cisco UCS Manager. If the policy is either set to default (not set) or a custom default (platform default), the problem is not seen.

Leave the policy on the default settings.

The message in ESX is being reported incorrectly by ESX and should be ignored. The root cause is that ESX is looking at the wrong pointer and reporting the incorrect status. This issue has no known ill effects to the function of ESX or the server.

Boot order in BIOS setup or F6 menus still show Local HDD even after removing the Local Disk option in the Cisco UCS Manager service profile. This is seen when the boot order is configured by the Cisco UCS Manager service profile with PXE eth0, PXE eth1, iSCSI iscsi0, iSCSI iscsi1, Local HDD. If you decide to remove the Local HDD option by deleting it from the boot policy service profile, after the server reboots, the boot order still shows the Local HDD in the BIOS boot order list. This behavior does not affect booting to PXE and iSCSI devices in the order configured.

Disable Local HDD manually using the following steps:

1. Boot the blade.

2. Press the F2 key when the message is displayed during the BIOS POST.

3. Wait until the BIOS completes its POST and invokes the Setup utility.

4. Choose the Boot Options tab.

5. Move the cursor down to Hard Drive BBS Priority and press enter to select this option.

6. Move the cursor to the hard drive that the user wants to disable and press Enter to configure the drive.

7. Move the cursor to the Disabled option and press Enter to disable the drive.

8. Save and reboot the blade.

While creating an SNMPv3 user, if the username is already assigned to local system users, instead of displaying an error, the configuration will be accepted, but a fault is raised and the configuration will not deploy.

While creating an SNMPv2 user with a community name that is the same as the local system the user will be accepted and deployed without any error or fault.

While creating a local system user, if the username is already assigned to an SNMPv3 user, then instead of displaying an error, the configuration will be accepted, but a fault is raised and the configuration will not deploy.

This issue happens only when the SNMPv3 username and system local username matches.

If the SNMPv3 user configuration is not deployed because of a name collision with local user, then either choose a different name for the SNMPv3 user or delete the local user for the configuration to be deployed.

If a local user configuration is not deployed because of name collision with the SNMPv3 user, then either choose a different name for the local user or delete the SNMPv3 user for the configuration to be deployed.

If a server is configured to boot from an iSCSI LUN, then disabling the primary and failover NIC from the host OS will result in the host losing its connection to its boot disk which can lead to a host OS panic or BSOD. This occurs when both the primary and failover vNICs are disabled from the host OS.

Do not disable the failover iSCSI vNIC from the host OS.

MAC address-based port security for Emulex converged Network Adapters (N20-AE0102) is not supported. You configure MAC address-based port security through the network control policy in the service profile. When MAC address-based port security is enabled, the fabric interconnect restricts traffic to packets that contain the MAC address that it first learns. This is either the source MAC address used in the FCoE Initialization Protocol packet, or the MAC address in an ethernet packet, whichever is sent first by the adapter. This configuration can result in either FCoE or Ethernet packets being dropped.

Disable MAC security on the service profile.

The link from the rack server adapter to the fabric interconnect port remains down if the SFP type is FET (Fabric extender transceiver). Currently the FET type is supported only between a fabric extender and a fabric interconnect. If the SFP used for the link between the IOM and the rack server adapter is an FET, the link will remain down.

Replace the SFP with one of the supported SFPs for rack server adapters.

Non-disruptive pending changes may not be shown on a service profile. When a service profile has a maintenance policy that defers the application of disrupting changes to the server, user can see what changes are pending and make further changes. Disruptive pending changes are always visible on the service profile, whereas non-disruptive changes may not be shown. Non-disruptive pending changes are only shown for user convenience.

This issue has no known workaround. This defect has no functional impact.

The server UUID displayed by ipmitool does not match that shown by the Cisco UCS Manager CLI. UCS UUID encoding follows pre SMBIOS 2.6 specified encoding, which is big-endian encoding. Ipmitool does not work well with that encoding. The SMBIOS 2.6 specification mandates mixed encoding (first 3 fields little-endian, last 3 big-endian), which is followed by ipmitool.

For example, The server detail from Cisco UCS Manager CLI shows

Dynamic UUID: 0699a6f3-1b81-45f8-a9f2-c1bbe089324e

# ipmitool -H 10.193.142.104 -U gurudev -P password mc guid

System GUID : f3a69906-811b-f845-a9f2-c1bbe089324e

Compared to Cisco UCS Manager CLI or GUI output, the first 3 fields f3a69906-811b-f845 show up differently in the output of ipmitool.

The following usage of ipmitool can be used as a workaround -

#ipmitool -H 10.193.142.104 -U gurudev -P password raw 0x06 0x37

06 99 a6 f3 1b 81 45 f8 a9 f2 c1 bb e0 89 32 4e

For a port profile with existing VIFs, if the “Max-Ports” setting is reduced from the currently configured value to a value less than the “Used-Ports” value reported for that port profile by VMware vCenter, this is a mis-configuration. The new value for “Max-Ports” for that port profile will only be updated in Cisco UCS Manager and its update in VMware Center will fail, causing a inconsistency between Cisco UCS Manager and VMware Center Server.

If the need arises to reduce the value of “Max-Ports” of a port profile, the new value should be at least the value of “Used-Ports” reported by the VMware Center for all the DVSes for that port profile (not lower than maximum of all the “Used-Ports” values). This constraint has to be ensured manually.
