All,
Customer who has 15K running Solaris 10 6/06 with 3510 array attached,
has a disk array failure
and ZFS was mirroring. The system panic and can't boot off either in
single user mode nor in multi-user mode.
The panic error shows:
IMPACT:panic[cpu512]/thread=2a1022a7cc0: ZFS: bad checksum (read on

Customer's main concern right now is to make the system bootable but it
seems couldn't do that since the bad disks is part
of the zfs filesystems. Is there a way to disable or clear out the bad
zfs filesystem so system can be booted?
Also i did search on the error "ZFS: bad checksum" error and i found
some bugs.
Any assistance on this issue is greatly appreciated. Customer's domain
is still down at this point.
TIA,
Arlina
