Intersight Management Mode

Intersight Managed Mode (IMM) is a new set of features introduced in Cisco Intersight to configure, deploy, and manage a Server Profile for B-Series, FI-managed C-Series servers. IMM introduces a new implementation of concepts first introduced with Cisco UCS Manager and moves ownership of the policy model into Cisco Intersight. Hence, policies, VLANs, and VSANs are created in advance and built into a Server Profile. Then, the Server Profile is assigned and deployed to a Cisco Intersight discovered B-Series or managed C-Series servers.

Note

Cisco UCS Infrastructure and Server FW version 4.1(2) enables an opt-in for IMM; a policy driven configuration platform for FIs and attached servers. When IMM is enabled, the entire UCS domain is reset to factory defaults and this will cause a disruption for workloads running on servers in the domain.

For more information, see https://intersight.com/help/resources#intersight_managed_mode.

Memory RAS Enhancements

This release introduces the following Memory RAS enhancements:

Intel Post Package Repair (PPR) uses additional spare capacity within the DDR4 DRAM to remap and replace faulty cell areas detected during system boot time. Remapping is permanent and persists through power-down and reboot.

Partial DIMM Mirroring enables better Virtualization Host Resiliance by creating a mirror copy of specific regions of memory cells, instead of keeping the complete half of the mirror copy. Memory mirrors, using up to 50% of capacity, can be specified in gigabytes or percentage of total capacity, across up to 4 mirrors, and can be configured across multiple IMCs or sockets. Partial mirroring cannot be used in connection with standard mirroring or ADDDC sparing.

Address Range allows the memory presented to the user to be limited to a specified subset of actual memory.

Intel® VMD and Intel® Virtual RAID on CPU (VRoC)

Intel® Volume Management Device (VMD) provides storage management options for NVMe drives, including surprise hot-plug and LED status management. Virtual RAID on CPU (VRoC) enables creating and managing RAID volumes within the BIOS of VMD-enabled NVMe SSD drives by using hardware logic inside the Intel Xeon processor. The Cisco implementation of VRoC, supported only on Intel NVMe drives, supports RAID 0 (striping), RAID 1 (mirroring), RAID 5 (striping with parity) and RAID 10 (combined mirroring and striping).

Feature Enhancements

A per-chassis fan control policy for B-Series servers allows a single policy to control the speed of all server fans in an enclosure.
Support for configuring vMedia mount as writable when both the following conditions are met:
- Device Type is HDD
- Protocol is NFS or CIFS
Intel^® Optane^™ Data Center persistent memory module support is extended to C480 M5ML servers.

Cisco UCS Manager and Cisco UCS C-Series Release Compatibility Matrix for C-Series Rack-Mount Servers

Cisco UCS C-Series Rack-Mount Servers are managed by built-in standalone software— Cisco Integrated Management Controller (Cisco IMC). However, when a C-Series Rack-Mount Server is integrated with Cisco UCS Manager, the Cisco IMC does not manage the server anymore.

Each Cisco UCS Manager release incorporates its corresponding C-Series Standalone release and some previous C-Series standalone releases. For example, Cisco UCS Manager Release 4.1(1) is integrated with C-Series Standalone Release 4.1(1) for the M5 servers, Release 4.0(2) for all the M4 servers, and Release 3.0(4) for all M3 servers. Hence, it supports all the M5, M4 and M3 servers supported by C-Series Standalone releases.

The following table lists the Cisco UCS Manager and C-Series software standalone releases for C-Series Rack-Mount Servers:

GB Connector Modules, Transceiver Modules, and Cables

Following is the list of Gb connector modules, transceiver modules, and supported cables:

Note

Transceiver modules and cables that are supported on a specific Fabric Interconnect are not always supported on all VIC adapters, IOMs, or FEXes that are compatible with that Fabric Interconnect. Detailed compatibility matrices for the transceiver modules are available here:https://www.cisco.com/c/en/us/support/interfaces-modules/transceiver-modules/products-device-support-tables-list.html
S-Class transceivers, for example, QSFP-40G-SR4-S, do not support FCoE.

UCS Manager Health and Pre-Upgrade Check Tool

The UCS Manager Health and Pre-Upgrade Check Tool provides automated health and pre-upgrade checks that are designed to ensure your clusters are healthy before you upgrade. It is imperative that this healthcheck is not just performed, but that you take corrective action on any cluster that is found to be unhealthy. Correct all issues reported by the UCS Manager health check before continuing.

Upgrade and Downgrade Guidelines

In a system with Cisco UCS 64108 Fabric Interconnects, you cannot downgrade from Cisco UCS Manager Release 4.1.

See the Cisco UCS Manager Firmware Management Guide, Release 4.1 section Firmware Upgrade to Cisco UCS Manager Release 4.1 for detailed upgrade paths.
When upgrading or downgrading systems using Intel Volume Management Device (VMD) for NVMe, the system will fail to boot if VMD is enabled or disabled in the BIOS after OS installation. Do not change the BIOS setting after OS installation.
Upgrading to the latest Intel firmware images in Release 4.1(1a), requires Cisco UCS Manager to be updated to Release 4.1(1a) as well.
RDMA upgrade/downgrade: if downgrading from RDMA-supported releases to non-RDMA-supported releases, you must manually remove all RDMA-related configurations before downgrade. If upgrading eNIC and eNIC RDMA drivers, upgrade all drivers to the same version at the same time; otherwise, functionality could be lost.

Downgrade Limitation for Cisco UCS C125 M5 Servers

Starting with Release 4.1(3), AMD Platform Secure Boot (PSB) is introduced in Cisco UCS C125 M5 servers that implements hardware-rooted boot integrity. Once you upgrade to release 4.1(3) or later, you cannot:
- downgrade Cisco UCS C125 M5 Rack Server Node based on 2nd generation AMD EPYC 7002 Series Processors (Rome) to any release earlier than 4.1(3).
- downgrade Cisco UCS C125 M5 Rack Server Node based on AMD EPYC 7001 (Naples) to any release earlier than 4.0(2k).

Capability Catalog

The Cisco UCS Manager Capability Catalog is a set of tunable parameters, strings, and rules. Cisco UCS uses the catalog to update the display and configurability of components such as newly qualified DIMMs and disk drives for servers.

The Capability Catalog is embedded in Cisco UCS Manager, but at times it is also released as a single image file to make updates easier.

The following table lists the PIDs added in this release and maps UCS software releases to the corresponding Capability Catalog file.

On Cisco UCS 6400 series Fabric Interconnect, when VLAN1 is configured as non-native VLAN, the OS/Blade vNIC sends VLAN1 tagged traffic to Fabric Interconnect and the Fabric Interconnect sends return traffic to blade with Vlan1 as untagged. Thereby, resulting in network connectivity issues.

Whereas, the C-series integrated traffic for non-native VLAN1 is not affected whether it is directly connected to C-series or through fabric extender.

This issue is resolved.

CSCvx88769

In situations during downgrade of Cisco UCS Manager from 4.2(x) to 4.1(3d) or earlier releases, Cisco UCS manager gets downgraded to 4.1(3d) or earlier release. And, if for some reason Fabric Interconnect reboot happens even before Fabric Interconnect gets downgraded to 4.1(x) or earlier releases, the Fabric Interconnect gets stuck in 4.2(x). This situation results in failure of user login.

The defect is partially resolved to enable user login through CLI when Cisco UCS manager is up. So that, the user can recover the setup through CLI.

Note

Cisco UCS Manager GUI will still not be accessible. For more information, see CSCvy90962 in the Open Caveats section.

Open Caveats for Release 4.1(3a)

The following caveats are open in Release 4.1(3a):


Defect ID	Symptom	Workaround	First Bundle Affected
CSCvx11527	During the upgrade of the infrastructure software bundle to the release 4.1(3a) for the first time, both the IOMs reboot to update its BIOS without waiting for the user acknowledgment. This reboot affects the domain setups where UCS 5108 chassis with 2408 I/O Modules (IOM) is connected to UCS 6454 or UCS 64108 Fabric Interconnects resulting a complete loss of storage and network connectivity.	The UCSM 4.1(3a) release has been deferred. If the IOM 2408 has already been upgraded to 4.1(3a) release, then that IOM has already received the updated BIOS and will not incur further reboots. For more information, see the deferral notice.	4.1(3a)
CSCvv64331	In a Rack-Mount server-only environment, due to multiple host entries in the DHCP leases or unavailability of DHCP leases, the server discovery and high availability fail.	Contact TAC to load the debug plugin on the Fabric Interconnect to restart the DHCP process and clear the DHCP leases. After the restart, DHCP re-assigns the IP addresses. Hence, server discovery will be successful.	2.5(1.1)
CSCvw76890	The delete operation triggered by a user from the Cisco UCS Manager GUI, will delete the cores. But, in case, if it is the switch core, the deleted switch core is restored after few seconds. The above issue is seen as the switch cores are available under both Cisco UCS Manager and Switch sides. The cores are restored from switch if it is not available under Cisco UCS Manager directory, as part of core monitoring.	Contact TAC to get the required core removed when there are space constraints.	4.1(3a)A
CSCvu90488	During Infrastructure upgrade of Cisco UCS 6400 Series Fabric Interconnects, the upgrade fails and retries multiple times continuously.	Restart Data Management Engine (DME) and reboot Fabric Interconnect to recover the setup.	4.1(2)A
CSCvv57606	On installing a M5 server in a chassis for the first time, a service profile may fail and throw the connection placement error. This issue is seen as the path is not being established for the adapter on Fabric Interconnect A and Fabric Interconnect B.	Re-acknowledge IOM on path that is missing to re-establish connectivity and associate the service profile.	4.0(4e)A
CSCvw58884	On applying Host Firmware Pack (HFP) of version 4.1(1d) from Cisco UCS Central, the multiple local-disk and storage-controller faults are reported on the UCS Manager Domains. These faults have occurred as the B-Series and C-Series bundles firmware package exists on the UCS Manager domain even after deleting the images post the service profile update.	Upload the same B-Series and C-Series bundles firmware package to the Cisco UCS Manager domain to clear the local-disk and storage-controller faults.	4.1(1c)A
CSCvv87212	After decommission and recommission of the Cisco UCSC-C240-M5SN server, the server gets discovered successfully. But, Cisco UCS Manager GUI and CLI show only B as the Conn Path and Conn Status instead of A and B for the server.	Re-acknowledge the affected server or decommission and recommission the affected server.	4.1(2a)A
CSCvw87665	During upgrade of Cisco UCS S3260 Storage Server from Cisco UCS Manager Release 4.0(4k)C release to Cisco UCS Manager Release 4.1(3)C release, the chassis profile association may get stuck with the following message: `waiting for board controller activation to complete(FSM-STAGE:sam:dme: EquipmentChassisAssociate:PollBrdCtlrActivation`	There is no known workaround.	4.0(4k)C
CSCvv15754	On the Cisco UCS domain running with a high capacity of servers (100+) and chassis, you might get a timeout error when you update VLANs for a UCS vNIC template with more number of VLANs (150+) through Cisco UCS Manager GUI.	VLANs can be added through the CLI of Cisco UCS Manager, using the following commands: `UCSM /org # scope org sub-org UCSM /org # scope vnic-templ templ_name UCSM /org/vnic-templ # create eth-if VLAN_name UCSM /org/vnic-templ/eth-if* # commit-buffer`	4.0(4c)A
CSCvw91528	After decommission and recommission of a chassis, the Power Save Policy Mode of the chassis is disabled.	If you have already enabled the power save mode before recommission, you have to manually enable the power save mode again after recommission of chassis. To enable the Power Save Policy mode, perform the following: Log in to Cisco UCS Manager GUI Navigate to Equipment > Policies > Global Policies. In the Power Save Policy Mode field, click Disable and then click Enable.	4.1(3)A
CSCvw93034	On the 6300 Series Fabric Interconnect with Micron M500IT SSD running a firmware version different from MC03.00 or MU05.00, the SSD will become unresponsive after approximately 28224 (or ~3.2 years) of accumulated Power-On-Hours. This will cause file system operations on the Fabric Interconnect to fail, and could even trigger a reboot of the Fabric Interconnect. A power cycle of the Fabric Interconnect restores normal operation of the SSD, which then will continue to operate normally for 1008 Power-On-Hours (or ~1.5 months) before the same condition will be hit again. This cycle will continue to repeat for each additional ~1.5 months of accumulated Power-On-Hours unless the firmware of the SSD is updated to resolve this behavior.	Open a TAC case; TAC can perform the firmware upgrade for the SSD manually without requiring a Fabric Interconnect reboot.	4.1(2b)A
CSCvw31796	During discovery of a new server, the pre-existing LUNs under NV and/or Persistent Memory, are not scrubbed even if a global scrub policy is in place.	During discovery of a new server, the pre-existing LUNs under NV and/or Persistent Memory, are not scrubbed even if a global scrub policy is in place. Associate the server with a service profile and add a scrub policy(with persistent memory/disks) to this service profile. Disassociation will cause the Persistent Memory and LUNs to be cleared. This is recommended only on trusted servers.	4.1(2.55)C
CSCvw57512	Disk scrub fails for PCH and UCS-M2-HWRAID contollers during factory reset of M5 Servers.	Attaching a scrub policy in a service profile and dis-associating will scrub the disks.	4.1(2.74)C
CSCvy46626	When upgrading to UCSM 4.1.3 firmware, you may see the following faults for the primary fabric interconnect, once the UCS Manager and subordinate fabric interconnect have been successfully upgraded to 4.1.3 while the primary fabric interconnect is still on old firmware version. `sys/switch-X/oui-pool-default` `[FSM:FAILED]: Deploy OUI to Fabric-Interconnect(FSM:sam:dme:FcpoolOuisDeploy).

Defect ID	Symptom	Workaround	First Bundle Affected
CSCvw49192	After upgrading to Cisco UCS Manager release 4.1(2b), some system configurations may be unable to perform power characterization. Hence, resulting in a POST failure (hang at loading PTU driver) and erroneous DIMM errors.	After upgrading to Cisco UCS Manager release 4.1(2b), apply or update the BIOS policy with the MemoryRefreshRate token set to 1x Refresh. Then, reboot the server to apply the BIOS policy.	4.1(2b)C
CSCvs72258	After changing the Best Effort weight or MTU value in the QOS configuration on Cisco UCS 6332 Fabric Interconnect of Cisco UCS Manager, an unexpected extended storage traffic disruption may be experienced.	There is no known workaround.	4.0(4c)A

Open Caveats for Release 4.1(2a)

The following caveats are open in Release 4.1(2a):


Defect ID	Symptom	Workaround	First Bundle Affected
CSCvh06851	When an adaptor that is sending both Drop and No-Drop QoS class traffic encounters conjestion, the IOM sends the incomplete value of the user-configured PFC priority map to the adaptor. Because of this, all QoS classes are treated as No-Drop, and the adaptor slows down both Drop and No-Drop traffic to the IOM.	There is no known workaround.	3.2(2b)A
CSCvs72258	After changing the Best Effort weight or MTU value in the QOS configuration on Cisco UCS 6332 Fabric Interconnect of Cisco UCS Manager, an unexpected extended storage traffic disruption may be experienced.	There is no known workaround.	4.0(4c)A

Behavior Changes and Known Limitations in Release 4.1(1a)

Failure of Secure LDAP after upgrade of UCS Infrastructure to Cisco UCS Manager Release 4.1(1a)

CSCvt31344—Cisco UCS 6200 and 6300 series Fabric Interconnects (FIs): After upgrade of UCS Infrastructure A-bundle to Cisco UCS Manager Release 4.1(1a) from any previous release, the user authentication fails when logging into Cisco UCS Manager through secure LDAP. This behaviour is expected after infrastructure upgrade, as OpenLDAP security has strengthened security for Cisco UCS 6200 and 6300 series FIs.

To ensure successful login to Cisco UCS manager through secure LDAP, do one of the following:

LDAP server needs a new multiple domain certificate. This new certificate must include all possible names of the LDAP server configured in Cisco UCS manager, like Fully Qualified Domain Name(FQDN), hostname, and IP address in Subject Alternative Name (SAN) extension field of the certificate.
Obtain the SANs of the current LDAP server certificate using the following command:
```
openssl s_client -connect <LDAP Provider ip/hostname>:636 | openssl x509 -noout -text | grep -b1 DNS
```
In Cisco UCS manager, update one of the SANs as the LDAP provider to LDAP group that is being used in the LDAP authentication.

Cisco UCS Manager Shows Complete Reboot Impact for Multiple Users

CSCvp45607—In releases prior to Cisco UCS Manager Release 4.1(1),when you clicked on Show Current User's Activities and then on the Acknowledge All checkbox, you could reboot all servers that had a pending reboot from all users without understanding the full impact.

Selecting the Acknowledge All checkbox in Cisco UCS Manager Release 4.1(1) and later releases automatically deactivates Show Current User's Activities to ensure full visibility of the reboot impacts.

Cisco UCS Manager GUI Displays the Correct PSU Order

CSCvq93295—When using UCS 6332-16UP Fabric Interconnect integrated with UCS C240 M5SX servers, there is a mismatch between the power supply unit (PSU) positions displayed by the Cisco UCS Manager GUI and mentioned in the server specification document.

The Cisco UCS Manager GUI displays the power supply unit (PSU) positions incorrectly as:

PSU 1 — Upper
PSU 2 — Lower

The server specification sheet displays the correct information:

PSU 01 — Lower
PSU 02 — Upper

In Cisco UCS Manager Release 4.1(1) and later releases, the GUI displays the PSU position correctly.

Cisco UCS Manager GUI Displays Chassis Statistics Incorrectly

After a UCS 5108 chassis is powered off, Cisco UCS Manager displays the chassis status as Inaccessible. However, all chassis status statistics and chassis PSU statistics are incorrectly either displayed as OK or based on previous known statistics.

Algorithm Support in OpenSSH to Log into Servers through the SSH

Starting with Cisco UCS Manager Release 4.1(1c), certain insecure ciphers are blocked by UCS Fabric Interconnects. To log into servers through the SSH protocol, you must use a version of OpenSSH that supports at least one algorithm in the following categories:

Key exchange algorithms
- For Cisco Fabric Interconnect 6454
  - diffie-hellman-group-exchange-sha256
  - diffie-hellman-group16-sha512
- For Cisco Fabric Interconnect 6248, 6324 and 63xx
  - diffie-hellman-group-exchange-sha256
  - diffie-hellman-group16-sha512
Encryption algorithms
- aes128-ctr
- aes192-ctr
- aes256-ctr
MAC algorithms
- hmac-sha2-256
- hmac-sha2-512

Libfabric and Open MPI

Cisco usNIC support in the Libfabric and Open MPI open source packages is readily available from their community web sites (http://libfabric.org/ and http://www.open-mpi.org/, respectively).

Cisco UCS Manager Release 3.1(3) and later releases no longer include Open MPI binary packages. Future UCS software driver bundles distributed through the usual Cisco software channels may not include binaries for the libfabric packages. Cisco engineers continue to be active, core contributors in both the Libfabric and Open MPI communities, and will actively develop and support users through the usual community or commercial ISV support mechanisms (e.g., IBM Spectrum MPI).
