Use Live Upgrade, is much easier...

With SVM still you can offline a leg of the mirror and then mount it as RO. So you wont be able to patch it. It is generally used to perform backups on live systems with minimal impact on the performance. then you have to sync the mirrors back again.

What you could do is split the mirror , fsck the slices from the inactive metadevices and verify that everything is ok. Patch the OS and if something goes wrong just boot from the leg you detached earlier... pretty much the same thing you could do with Live Upgrade but manually... hence... do it with Live Upgrade.

Live upgrade has many many options for different scenarios... just look the one fits better to you. You can find the full documentation with examples at Oracle site under the reference manual section.

Cheers

what if i cannot do live update or use any graphical interface tool ?

my server cannot connect to outside internet, all patching must be done internally. Smilie
