Hi SuperIO,
This sounds perfectly normal as the system uses RAID6.
For example, given the following configuration:
sysadmin@dd630# disk show state
Enclosure Disk
1 2 3 4 5 6 7 8 9 10 11 12
--------- -------------------------------------
1 . . . . . s . . . . . .
--------- -------------------------------------
So the above shows that disk 1.6 is currently spare.
Should a non-spare disk in the above configuration fail, lets say 1.10 for example, then disk 1.6 would be it's replacement and used to rebuild the RAID configuration onto, for example:
sysadmin@dd630# disk show state
Enclosure Disk
1 2 3 4 5 6 7 8 9 10 11 12
--------- -------------------------------------
1 . . . . . R . . . F . .
--------- -------------------------------------
Legend State Count
------ ---------------------------- -----
. In Use Disks 10
R Spare (reconstructing) Disks 1
F Failed Disks 1
------ ---------------------------- -----
Total 12 disks
Disk Disks Progress Remaining
Group Reconstructing (%) (minutes)
----- -------------- -------- ---------
dg0 1.6 0 174
----- -------------- -------- ---------
When disk 1.10 is replaced correctly, it will then become the 'spare' for this enclosure. For example:
(assume the rebuild has already completed)
sysadmin@dd630# disk show state
Enclosure Disk
1 2 3 4 5 6 7 8 9 10 11 12
--------- -------------------------------------
1 . . . . . . . . . s . .
--------- -------------------------------------
cheers, Rich.
