The procedure to replace and restore a parity disk is the same as for a data disk. A
parity disk failure would be discovered while loading content. At the point of disk
failure, the loading operation ceases. As with a data disk, you use the

-r

option to

mfs repair

to restore the parity disk.

Note –

The status of a disk as failed does not persist across a reboot. If you

experience a disk failure, then reboot, you must explicitly fail the disk, with a
command such as:

Following this command, follow the procedure specified above to replace the failed
disk.

If you experience multiple, overlapping disk failures, you must restore the entire
contents of the MFS from a backup source, using

smc_tar

;

smc_copy

; or

ftp

, in

conjunction with the Sun MediaCenter FTP daemon. You might need to use the

smc_tar

’s

w

option, which allows you to overwrite existing content.

Note –

Two overlapping disk failures result in a system panic.

If you have to remake the MFS, use the following command:

The

mkmfs

command is described in the Sun MediaCenter Server Service Manual.

server# mfs repair -F -d /dev/rdsk/c1t4d0s2 -v

# mkmfs -f /etc/opt/SUNWsms/mfs.file
