Removing disk array

Russell W. Roth — Wed, 01 Jun 2011 14:21:28 GMT

We recently lost an old MSA that we are not going to replace. (It housed devel & test instances which have been moved to a SAN.) IOSCAN shows "NO_HW" for these H'ware paths. Ignite notes at the end of it's output:
NOTE: diskinfo failed for device at: /dev/rdsk/c10t0d5
NOTE: diskinfo failed for device at: /dev/rdsk/c10t0d3
NOTE: diskinfo failed for device at: /dev/rdsk/c10t0d2

Do I just run rmsf on these files (and the /dev/dsk files), or is there more?

You should at least remove any LVM related information (vgexport) and fstab entries.

The NO_HW will be gone after next reboot.

Shalom,

If its 11.31 rmsf -x will help clean up now.

The NO_HW will simply be there until you clean up and reboot the system.

Ah. I should have mentioned it is on 11.23. Thanks, to both of you.

Russ, Just fyi, I've came across the similar situation of having many NO_HW in the ioscan output. As said above, a reboot did the trick!

That seems to have taken care of it. Thanks to all.
