Rebuilding RAID Drives

A RAID drive may fail and may require manual intervention to rebuild one of the physical drives in a logical pair during normal operation.

RAIDed disks, also termed RAID arrays, get arranged in logical pairs. A single logical pair comprises two physical drives. The system keeps the pair of drives in sync with the same data in real time to provide redundancy ultimately for data integrity and assurance. When one physical drive fails to synchronize or begins to experience read or write failures, you may need to rebuild the drive. Many things can cause the failure, but the main concern remains whether the data in a logical drive pair is compromised due to failures in one of the physical drives.

Monitoring software usually detects RAID failures, and failures get reported as a failed drive or a loss of drive redundancy. The procedure for rebuilding a failing drive follows and applies to all Cisco MCS model 7825, 7835, and 7845 servers.

First, check the status of the RAID array by using the CLI show hardware command and verify whether the Status field reads Ok or Okay. An example follows:

admin:show hardware
HW Platform       : 7835I
Processors        : 1
Type              : Intel(R) Xeon(TM) CPU 3.06GHz
CPU Speed         : 3066
Memory            : 2048 MBytes
Object ID         : 1.3.6.1.4.1.9.1.585
OS Version        : UCOS 2.0.1.0-37
RAID Details      :
Found 1 IBM ServeRAID controller(s).
Read configuration has been initiated for controller 1...
----------------------------------------------------------------------
Logical drive information
----------------------------------------------------------------------
 Logical drive number 1
   Status of logical drive        : Okay (OKAY)
   RAID level                     : 1
   Size (in MB)                   : 70006
   Write cache status             : Temporary write through (TWT)
   Number of chunks               : 2
   Stripe-unit size               : 8 KB
   Access blocked                 : No
   Part of array                  : A
Array A stripe order (Channel/SCSI ID)  : 1,0 1,1 Command completed successfully.

If the RAID array status field does not read Ok or Okay (for example, shows Degraded or Critical), perform the following steps:


Step 1 Log in to console and enter the CLI command, utils system shutdown.

Step 2 Power off the server (press power off button).

Step 3 Extract the failed disk drive.

Step 4 Power up the server (press power on button).

If the server is an IBM server (for example, a 7825I, 7835I, or 7845I), the following menu will appear during system reboot:

1:ServeRAID-5i Slot 2, Logical drv=1, Firmware=7.12.07, Status=Fail
1 Drive(s) not responding or found at new location(s)
Press F2 Detailed information
          F4 Retry the command
          F5 Change the configuration and set the drive(s) defunct
          F10 Continue without changing the configuration

Step 5 Press F5

Step 6 After the login prompt appears in the console window, log in and check the status of the RAID array by using the CLI show hardware command; the Status field should read Degraded or Critical.

Step 7 Insert the failed disk drive into the original slot; be sure to lock it properly in place.

Step 8 Check the status of the RAID array by using the CLI show hardware command; the Status field will read Rebuilding or Critical.

Step 9 After an hour, recheck the status of the RAID array by using the CLI show hardware command and verify that the Status field reads Ok or Okay.

If the status does not read Ok or Okay, you may need to replace the physical drive.
