8-8 Sun MediaCenter Server Administrator’s Guide • December 1997
Following this command, use the mfs repair commands described above to
replace the failed disk.
Use of mfs repair is appropriate only for single disk failures. Two, overlapping
disk failures cause the server to panic. If you experience the failure of more than one
disk, you must use smc_copy or ftp, in conjunction with the Sun MediaCenter FTP
daemon, to restore your original data from backup storage.
For a given disk, you might receive a number of “soft errors,” such as SCSI read
errors that were corrected upon retry. As specified in the preceding section, these
errors do not, in themselves, constitute a disk failure. If you are concerned about
recurring soft errors for a particular disk, you can use a command such as the one
below, to explicitly fail the disk.
Following completion of this command, you can then replace the now-failed disk,
following the procedure described in Section 8.3, “Replacing a Failed Disk.”
8.2.4 mkmfs
The mkmfs utility creates an MFS. This command is automatically invoked by the
pkgadd installation process. You only need to invoke this utility if you reconfigure
the data and parity disks used by the MFS. The mkmfs utility is analogous to the
Unix mkfs (1M) utility.
mkmfs usage is as follows:
server# mfs repair -F -d /dev/rdsk/c1t3d0s2 -v
/opt/SUNWsms/mfs/bin/mkmfs [ -f <config file> ]
Caution – mkmfs disables access to all MFS files in existence prior to your
running the command. After running mkmfs, you must re-run mfs record to
re-create any media files that had previously existed.
