BL 860c - Failed disk on IR Volume on SAS Controller

Hello,

I've got a BL 860c with 2 disk mirrored in a unique IR Volume.
One of the 2 disk is gone:

/#sasmgr get_info -D /dev/sasd1 -q raid

Mon Dec 14 17:45:54 2009

---------- PHYSICAL DRIVES ----------
LUN dsf SAS Address Enclosure Bay Size(MB)

/dev/rdsk/c0t1d0 0x500000e01fde6172 1 1 70007

---------- LOGICAL DRIVE 2 ----------

Raid Level : RAID 1
Volume sas address : 0x4a50daed3b452d4
Device Special File : /dev/rdsk/c0t0d0
Raid State : DEGRADED
Raid Status Flag : ENABLED
Raid Size : 69618
Rebuild Rate : 0.00 %
Rebuild Progress : 100.00 %

Participating Physical Drive(s) :

SAS Address Enc Bay Size(MB) Type State

0x5000c50012a0a021 1 2 70007 PRIMARY ONLINE

How can I insert the new one disk on this Raid configuration?

Thanks in advance.

Re: BL 860c - Failed disk on IR Volume on SAS Controller

Remove the failed disk if it's still in the slot. (If it's in the slot but the sasmgr command reports it as missing, it means the electronics of the disk has totally died.)

Insert a new disk of suitable size in the empty slot.

Usually the controller would automatically start to rebuild the RAID array as soon as it sees a new unused disk in place of a failed one, but this auto-rebuild may have been disabled by setting the rebuild rate to 0 %.

Use the sasmgr command to adjust the rebuild rate to a suitable value. For example, this command would set the controller to use 20% of its disk I/O capacity for RAID rebuild:

sasmgr set_attr -D /dev/sasd1 -q raid -q raid_vol=2 -q rebuild_rate=20

The disk in SAS RAID 1068 controller is hot pluggable.
You can replaced the disk online, by checking the specific slot from the sasmgr command.
