How to detach mirror disks in Solaris? Assuming we us SVM, we normally do this like this, manually:<\/p>\n

metastat -c d0 (verify disk components)
\neeprom bood-device (further verify the boot disk)
\nsynch;
\nmetadetach rootdev detachdevice<\/p>\n

or put it a script for repetitive use and to avoice typo mistakes:<\/p>\n
