WAE 674 RAID Failure

I replaced the disk in Slot 3, which was defective.  After replacement, the disk showed "Online" in show disk detail within 15 mins of replacement.  This seemed odd, it usually requires more than 1 hour to rebuild a disk.   However, the RAID-5 status showed "Critical".

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

When I execute a "disk logical shutdown", reload, then attempt to execute "disk recreate-raid" I get this returned:

Failed to remove RAID Logical drive. (1,2)
Controllers found: 1

A selected physical drive is not available for use.

Command aborted.
Failed to create RAID Logical drive. (1,2)
Please, verify the disk does not contain mounted file system that remain in use.
Execute the command "(config)#disk logical shutdown" and reload the device before the array is recreated.

Re: WAE 674 RAID Failure

Thanks for your response.

What can I do in a case like below?

043879-0203A-WAAS1#disk disk-name disk03 replace

exec_disk: Invalid disk number for the current platform

The disk appears to exist:

043879-0203A-WAAS1#sh disk detail

RAID Physical disk information:

disk00: Ready 3QP2B8BF 286102 MB

disk02: Ready JLVVUBVC 286102 MB

disk03: Ready 3QP2B712 286102 MB

Thanks,

Re: WAE 674 RAID Failure

Hi James,

The problem, I believe is here:

RAID Physical disk information:

  disk00: Ready                      3QP2B8BF    286102 MB

  disk02: Ready                      JLVVUBVC    286102 MB

  disk03: Ready                      3QP2B712    286102 MB

If you check the output, it says disk01 is missing. One thing we should try is - remove disk03 and put it in place of disk01.

Further, the disks should be in "online" state, not "Ready" state. This may be hardware problem with RAID controller.

Anyway, here is the last option we can apply:

Use the system recovery process, if you can. The steps you may want to perform are step 7: Rebuild RAID. And then Step 8: Install .bin image.

Let us know how it goes.

Thanks.
