Spare disk - hot standby?

[Torsten.]

IMHO the controller won't allow modifications as long as there is a failed drive. Put back the drive, assign the spare and try again.

BTW, what driver version are you currently using?

swlist |grep -i raid

[Ratzie]

RAID-00 B.11.11.01 PCI RAID; Supptd HW=A5856A
RAID-01 B.11.11.0709 RAID SA; Supptd HW=A7143A/A9890A/A9891A


That makes absolutely no sense.

If I can 6 logical drives that are RAID 1.
the chassis only holds 14 drives.
I have to have a spare pre-assigned to the logical disk. Well that is impossible since I do not have enough disks.
Can i pre-assign a spare disk to more then one logical?

[Ratzie]

And my next question, is how do I delete that spare, that I do not have assigned to a logical...

The only command I see is to delete spare from logical.

[Torsten.]

I don't know how did you assign the spare, because you did not share this information.

IMHO it makes sense to share the spare disk between several logical drives - would you agree?

[Ratzie]

In a previous reply:
"So now I am in a pickle...
I assigned the disk as a spare:
saconfig /dev/ciss4 -A 0 -s 1:8"

I guess I should have been clearer.

I am very lucky that this is a test box.

[Torsten.]

So the spare disk is already assigned to logical drive 0.

If you put back the "failed" drive you can assign this disk to your other logical drives.

Do this first and try again to "fail" a disk or "fail" a disk in logical drive 0.

[Torsten.]

Any results?

[Ratzie]

I put the failed drive in, deleted the spare.
I was under the impression, that when I assigned the spare -A 0 -s 1:8
That I was assigning it as RAID 0. Me bad.

Took how many correspondents to figure this out!
I have deleted ALL configuration and will try to break again.

I am going to try assigning to multiple logicals. From the notes I do not know if this is possible.

Will update.

[Ratzie]

So unless I am missing something, you can not assign a spare disk to multiple logicals :(

Which does not make sense.

# saconfig /dev/ciss4 -A 0 1 -s 1:8
Improper syntax

[Uwe Zessin]

It says "improper syntax", not that you cannot do that. I'm not familiar with the 'saconfig' command (I assume that -A specifies the logical disk), but I would try it with two separate commands:
# saconfig /dev/ciss4 -A 0 -s 1:8
# saconfig /dev/ciss4 -A 1 -s 1:8
