CSCvf34445 | There were no defects filed with this field notice at the time of publication. |
The hard disk manufacturer for AIR-SRVR-300GB-HD= has identified specific Cisco Prime Appliances (PRIME-NCS-APL-K9) that are vulnerable to RAID failures, which may result in data loss.
The Cisco Prime Infrastructure (or NCS) physical appliance, PRIME-NCS-APL-K9, comes with four Hard Disk Drives (HDDs) of 300-GB capacity. These HDDs are deployed in a RAID-5 configuration. Here are some important details about the RAID-5 configuration:
On the Cisco Prime Infrastructure physical appliance, one or more HDDs in the RAID might fail. When this occurs, the LED on the failed HDD is red.
This alarm message is displayed on the Cisco Prime dashboard when you navigate to Monitor >Alarms and Events for the System Category:
Raid is Bad Detect rebuild progress...
Note: You can also select the System Category from the Alarm Summary panel (located near the lower-right section of a PI web page) in order to view all of the system-related alarms.
Note: Read all of the instructions that are described in this document before you proceed with this workaround.
Important: With the Cisco Prime Infrastructure physical appliance powered-up, replace all four of the HDDs (AIR-SRVR-300GB-HD=) in each of the affected appliances, one disk at a time. Ensure that the RAID rebuild is complete before you proceed with the next HDD replacement. This procedure can take one to three hours, dependent upon the size of the data on the HDDs.
HDD Replacement Preparation
Before you begin the HDD hot-swap, complete these steps:
ade # sudo /opt/MegaRAID/MegaCli/MegaCli64 -LDInfo -Lall -aALL | grep RAID RAID Level: Primary-5, Secondary-0, RAID Level Qualifier-3As you can see from the command output: ['Primary-5, Secondary-0, RAID Level Qualifier-3'] = RAID-5. Refer to the Explanation of Raid Levels section of the MegaCLI, Raid Levels article for more details about RAID.
HDD # | Disk Activity Indicator LED | Disk Status Indicator LED | Comment |
---|---|---|---|
1 | Green (Flashing) | Green (Flashing) | The HDD is running normally and flashes when there is HDD activity. |
2 | Red (Flashing) | Yellow | There is a malfunction with this HDD. Replace it immediately. |
3 | Green (Flashing) | Yellow (Flashing) | The RAID-5 disk reconfiguration is in progress. Wait for the Status indicator to switch off. If there is no HDD activity, then that LED might be turned off. |
4 | LED is not lit | LED is not lit | If this occurs momentarily after you insert the HDD, then it is likely that it is not inserted correctly. Remove the HDD and reinsert it in order to ensure that it is properly connected to the back plane. During normal operation, the LEDs are usually in the off state. However, if there is activity on the HDD, the Activity Indicator LED briefly flashes green. |
Here are some important notes to keep in mind before you swap any HDD:
HDD Replacement Procedure
Refer to this illustration and complete the HDD replacement steps in order to hot-swap the affected HDDs:
The images that are provided in this section illustrate how to identify the Serial Number (SN) of your Cisco Prime Infrastructure physical appliance. Use the SN with the Cisco Serial Number Validation Tool in order to verify whether your Cisco Prime Infrastructure physical appliance requires HDDs replacement.
