Ситуация в следующем: есть сервер на котором крутится solaris и настроен raid. Привожу вывод команды metastat

На сервере планируются работы, чтобы сохранить работоспособность системы в качестве плана отката планирую отстрелить зеркала и в случае неполадок загружаться с них. При помощи команды metadetach я буду отстреливать зеркала, НО КАК ЗАТЕМ ЗАГРУЖАТСЯ СНИХ? как дать системе понять что нужно грузится с тех зеркал?
нашел материал, но он для веритаса http://seer.entsupport.symantec.com/docs/275374.htm

я так понял что над отстрелянными зеркалами я дальше проделываю следующие шаги, по инструкции:
4. Edit the following files to make the root mirror disk bootable without VERITAS Volume Manager (tm):

# mount /dev/dsk/c1t1d0s0 /mnt
# cd /mnt/etc
# cp -p system system.orig
# cp -p vfstab vfstab.orig
# cp -p vfstab.prevm vfstab

Change the c#t#d# number in above file to ensure the correct partitions will be referenced in the vfstab file:

# touch /mnt/etc/vx/reconfig.d/state.d/install-db

Edit /mnt/etc/system and comment out following lines using the "*" character:

Before changes:
rootdev ..
set vxio ..

After changes:
* rootdev ..
* set vxio ..

5. Unmount the root mirror's / partition
# umount /mnt

и как я понял в случае неполадки мне придется лишь переставить жесткие диски местами в отсеках? и уже основной диск metattach как зеркало
