We just had a tremendous power spike that knocked one of our 5200 SENA boxes
offline. It has restarted but I have a problem. I have searched the
sunmanagers.org archive and sun but to no immediate avail and I need this
resolved ASAP.
The logical volumes now show disks needing maintenance. No big deal. I do
a metareplace -e but this time, which is different than times past, I get an
error that the disk "overlaps with device in metadevice state database"
Upon further investigation, I notice that the controller number has changed
and now instead of c3t1d0s2 being used, the disk needing maintenance shows
as c4t1d0s2.
What can I do to resync my logical volumes? Here's an example of one of
them:
# metastat d2
d2: Mirror
Submirror 0: d21
State: Needs maintenance
Submirror 1: d22
State: Needs maintenance
Pass: 1
Read option: roundrobin (default)
Write option: parallel (default)
Size: 141435392 blocks
d21: Submirror of d2
State: Needs maintenance
Invoke: metareplace d2 c4t5d0s2 <new device>
Size: 141435392 blocks
Stripe 0: (interlace: 32 blocks)
Device Start Block Dbase State Reloc Hot Spare
c4t3d0s2 9424 No Okay Yes
c4t4d0s2 9424 No Okay Yes
c4t5d0s2 9424 No Maintenance Yes
c4t6d0s2 9424 No Maintenance Yes
d22: Submirror of d2
State: Needs maintenance
Invoke: after replacing "Maintenance" components:
metareplace d2 c0t21d0s2 <new device>
Size: 141435392 blocks
Stripe 0: (interlace: 32 blocks)
