How to replace the mirror disk on Solaris 10
Take backup first:
# metastat –p >/var/tmp/metastat-p-b4repalcement
# metastat –t >/var/tmp/metastat-t-b4replacement
# metadb –i >/var/tmp/metadb-i-b4replacement
# echo | format >/var/tmp/format-b4replacement
# iostat –en >/var/tmp/iostat-en-b4repalcement
# ifconfig –a >/var/tmp/ifconfig-a-b4repalcement
# echo | format
