8. Terminate all other metadevice activity on the disk.
Check
metastat
output for other slices of the disk used by metadevices that
cannot be detached (stripes not in mirrors, etc.). These metadevices must be
unmounted if they contain file systems, or they must otherwise be taken off line.
Refer to the
prtvtoc(1M)
man page for more information.
9. Unmount any file systems on the disk.
Note -
If the file system(s) are on a disk that is failing or has failed, the
umount
operation may not complete. A large number of error messages may be displayed
in the system console and in the
/var
directory during the
umount
operation. If
the
umount
operation does not complete, you may have to restart the system.
For each file system returned, type:
# umount
filesystem
where filesystem is the first field for each line returned in Step 1 on page 17.
For example:
# umount /export/home
# umount /export/home2
Removing and Replacing the Disk Drive
Refer to the Sun Ultra 450 Workstation Owner’s Guide or Ultra Enterprise 450
Server Owner’s Guide for instructions on how to remove and replace disk drives.
Restoring the Solstice DiskSuite Diskset Files
Use the following procedure to configure a slice on a disk to be used with the
Solstice DiskSuite system.
1. Restore the disk partitioning.
If you have saved the disk partitioning to a file, you may restore it with
fmthard
. For example:
# fmthard -s /etc/c1t2d0s0.vtoc
/dev/rdsk/c1t2d0s0
If you have not saved the disk partitioning, use the
format
(
1M
) or
fmthard
(
1M
)
commands to repartition the disk.
