replace disk (submirror)

[kilafish]

Hi All,

Coming from the HP-UX world I was wondering how to replace a faulty disk on a system using disk suite, which are mirrored. Am I in the right ball park with the following steps?

Identify disk is faulty and replace
re-format new disk with exact slices
re-create metadevices on mirrored disk (metainit)
re-establish mirror (metattach)

Are there any other steps involved?

Also, are the different steps when the primary disk of the mirror fails?

Thanks
Achille

You can detach either submirror without problem unless the "/ " partitian is the one you have problems with. In this case you will need to run the metaroot command to change the boot device ie. metaroot /dev/dsk/c1t0d0s0
Then you will be able to clear the mirror that is faulty and replace. If the faulty disk is the boot disk you will have to change the boot device in the EEPROM settings so you can boot the system again. Download the DiskSuit manual from "docs.sun.com" for more details.
