metadevices unavailable after reboot

Sun V880, Solaris 9, 112233_04 in uname but 112233_12 is installed.

We had a small problem with a critical process that made us reboot the system.

After coming back up the system complained that the metadevices (/dev/md/dsk/d10,/dev/md/dsk/d11)
were not valid devices (no such device). All the commands that we usually use (metastat, metadb, metainit) fail with various errors depending on which one is run.

The programs in /sbin seem to run, but they fail thus:

# metastat
metastat : artemis : invalid argument
# metadb
metadb : artemis : invalid address

The programs in /usr/sbin fail totally:

# metastat
Bus Error(coredump)
# metadb
Bus Error(coredump)

The only indication I could get that anything is being seen at all was with /sbin/metastat:

# metastat -t d10
metastat : artemis : d10: invalid interlace

I thought that perhaps sometime in the past few weeks a patch had been partially installed, so I got the latest recommended set for Solaris 9 (which has updates to DiskSuite) and installed. No change at all.

I really need some help here. I have backup of the volumes but I need to get them back online to restore if necessary. It's been six hours and I am getting nowhere.

Thanks for any advice or tips you might have.
