Add missing disk to hardware raid

[debtboy]

Sorry, it appears there may have been something wrong with that physical (unused) disk.

I replaced it with another and a new Logical Drive (132) was created automatically.

Now from the EFI shell, I was able delete LD132 and LD5 leaving me with the following...

I have 2 drives:

Enclosure 1 Bay 7 (boot disk)

Enclosure 1 Bay 8 (new unused disk)

Is there a way to make /dev/rdsk/c0t3d0 part of LD7 without loosing the boot disk data?

Thank you again

[Torsten.]

Did you insert the disk from slot 8 into slot 0?

It doesn't look so in your output.

Try this:

- remove disk from slot 8

- do

    # sasmgr -f reset -D /dev/sasd_

- insert disk in slot 0

- check status

The system waits for a disk in slot 0 for a rebuild.

If all does not work, we can add the disk as spare.

Thanks for your reply,

removed disk from slot 8

reset sasd1

replaced in slot 1

Status...

Device (/dev/sasd1) has been RESET.
# sasmgr get_info -D /dev/sasd1 -q raid

I really appreciate your time and patience

[Torsten. · Accepted solution]

Somehow the controller became confused, the normal order is from slot 1 to slot 8, but it expect a disk in encl. 0 slot 0.

I would first delete LD5 (if you don't need it):

# sasmgr delete -D /dev/sasd0 -q raid -q raid_vol=5

then add the disk in slot 8 (move it back to slot 8) as spare:

# sasmgr add -D /dev/sasd0 -q raid -q spare -q enc_bay=1:8

[debtboy]

Yes I agree, the controller seems to have lost it's reference, as there is no enclosure 0 nor slot 0.

LD5 has been deleted, but I'm not going to create a spare right now.

I really appreciate all the help you've given me,

Thank You
