Hi,
one disk has problems in my StoreEdge T3 box. It's RAID5 with one
standby disk:
volume capacity raid data standby
v0 253.4 GB 5 u1d1-8 u1d9
After the disk problem, fru stat shows
..
DISK STATUS STATE ROLE PORT1 PORT2 TEMP VOLUME
------ ------- ---------- ---------- --------- --------- ---- ------
u1d1 ready enabled data disk ready ready 35 v0
u1d2 ready enabled data disk ready ready 34 v0
u1d3 fault substituted data disk notReady notReady - v0
u1d4 ready enabled data disk ready ready 34 v0
u1d5 ready enabled data disk ready ready 34 v0
u1d6 ready enabled data disk ready ready 34 v0
u1d7 ready enabled data disk ready ready 34 v0
u1d8 ready enabled data disk ready ready 35 v0
u1d9 ready enabled standby ready ready 34 v0
..
After one disk failed I would assume that the 'role' of the standby
disk changes to 'data disk' but it's still 'standby'.
So question is: is the standby disk actually used in the RAID5
(and therefore the RAID5 would survive another disk failure).
If not: does
vol recon u1d3 to_standby
incorporate the standby disk into the RAID5 array? Why didn't
that happen automaticly?????
Neverthelesss I will order a new disk ASAP.
Thx for any info,
Achim
