Thanks

I tried clearing the volume with metaclear –a , however I believe its only going to work on unmounted volumes.

Root is mount on d10 and var is mount on d30 as I cant take this file system offline , can you please suggest as what need to be done?

Please see the output of df

Solaris Volume Manager Administration Guide


this article is very clear and should take you down the right path. sun has some of the better documentation out there so use this to your advantage.

you will want to run metaroot on root slice, init 6, metaclear -r d10 and then metaclear d11. do the same for /var just not the metaroot.

make sure you check /etc/system and /etc/vfstab. you'll need to clean up vfstab.
