Critical situation HSG60 Fail disk on Raid 0+1 and not Spare Disk in MA

Hello managers...

I have an MA6000/HSG60 with 12 disks 36 GB and ACS 8.5L. One of this disks failed, it is a
member of a raid 0+1 (10 MEMBERS)(the others 2 SLOTS in the enclosure is a Raid-1).
I just wanted to know if i could just pull the non-working disk out and put
the new one in?
With my current understanding, the HSG60 should begin with the
reconstruction of the disk after the new disk has been inserted.

Is that right or do i have to do a "delete DISKxxxxx" and after that a "add
disk ..." on the HSG60 in order to get this disk to work (and to get the
HSG60 to reconstruct the Raidset)??

AND VERY IMPORTANT: I HAVE NOT ANY SPARE DISK.

My situation is critical, help please

thanks for all your help.

No, the HSG does not work like a Smart Array controller - you have to fix it yourself.

Before you start changing anything, please execute the following commands and safe them away for future reference:

> show disks full
> show mirrorsets full
> show stripesets full
> show units full
> show failedset

Next, you need to find out the name of the disk that failed and which mirrorset is reduced. Physically replace the disk and remove the entry from the FAILEDSET:

> delete failedset DISKpttll

Add it back to the reduced mirrorset:

> set Mn replace=DISKpttll

The mirrorset should now rebuild.

If you need more help, please take the output from the first step and post it as a .TXT attachment - please do not simply cut and paste it into the message area, because multiple spaces will be stripped to one and that makes the output hard to read.
