One reply asking for more information and about 20 or so OOO messages.
Those MUAs must be a bear to configure.
The system does not see SUNWmdu or SUNWmdr as installed. I copied the
files for those packages from patch 113073-13 to /sbin and /usr/sbin and
was able to re-initialize the md database and recreate the metadevices.
Now all the commands work. Not a great solution -- I have no idea why
those packages are not showing installed.
We also found that /etc/lvm/mddb.cf was empty as of the date of the prior
reboot (when the recommended patch cluster was last installed). The
/kernel/drv/md.conf file also had an empty "MDD database info" segment. I
was not able to recover the data on the metadevices, but I could recreated
them. The next test will be to see if they survive a reboot.
