Repair mirror

I am new to Solaris Volume Manager and need some help. I have a raid 1 and both submirrors have state "Needs maintenance", how can I repair the mirror? I have invoked "metasync", but it does not work.Thank you

Normally that indicates that a disk has hardware problems.

You should look in /var/adm/messages

to look for io operation errors

and do a

iostat -En | grep -i soft

to look for hard errors.

Assuming it is a failed disk you will need to replade it with this procedure

But if it is a spurious error then you can force it back to clean state with a

metareplace -e mirror submirror command
