Hello Everyone, 1st time question. I have access to 2 systems (solaris 8 on an old netra 1125), one runs superb and the other has sub mirror problems. Not versed at mirroring disks, so just looking for some guidance.

1st difference during reboot:

One or more submirrors are not attached
Submirror d33 is not attached to mirror d73.

Tried metattach d73 d33, comes back d73: unit not setup

This suggests non existing meta devices, however via the format output and the metastat output, d73 seems well.

The only other output I currently have is from (bad site ):

extdsk1/d73: Mirror
Submirror 1: extdsk1/d43
State: Okay
Pass: 1
Read option: roundrobin (default)
Write option: parallel (default)
Size: 16496712 blocks

extdsk1/d43: Submirror of extdsk1/d73
State: Okay
Size: 16496712 blocks
Stripe 0:
Device Start Block Dbase State Hot Spare
c2t10d0s3 0 No Okay

The good site has the same as above with the addition at the bottom of:


extdsk1/d33: Submirror of extdsk1/d73
State: Okay
Size: 16496712 blocks
Stripe 0:
Device Start Block Dbase State Hot Spare
c1t2d0s3 0 No Okay



Any thoughts as I'm stumbling and learning from this? I was focusing on d73 itself, but maybe thoughts on d33?

Thanks,
Az1nick

Maybe you to give its fullname?

Well, thanks for the input. After several reboots, it finally mounted. No conclusive reason as to why.

Thanks for the update! even while no root cause is identified…
