metadb - md: cannot load driver ssd



I have a Solaris 8 system running on a mirror. Recently due to some
database operations, there are multiple disks appears to have some
errors on the metastat (see below 2). Also, I have seen some error in
the dmesg log (see below 1).

I believe these are soft error. Can someone give some advise of how
can this be resolved?

Thank you!!
