To convert the byte order of a file system
1
Determine the disk layout version of the file system that you will migrate:
# fstyp -v /dev/vx/rdsk/diskgroup/volume | grep version
magic a501fcf5 version 7 ctime Thu Jun 1 16:16:53 2006
Only file systems with Version 6 or later disk layout can be converted. If the
file system has an earlier disk layout version, convert the file system to
Version 6 or Version 7 disk layout before proceeding.
See the vxfsconvert(1M) manual page.
See the vxupgrade(1M) manual page.
2
Perform a full file system back up. Failure to do so could result in data loss
or data corruption under some failure scenarios in which restoring from the
backup is required.
3
Designate a file system with free space where fscdsconv may create a file
that will contain recovery information for usage in the event of a failed
conversion.
Depending on the nature of the file system to be converted, for example if it
is mirrored, you may wish to designate the recovery file to reside in a file
system with the same level of failure tolerance. Having the same level of
failure tolerance reduces the number of failure scenarios that would require
restoration from the backup.
4
Unmount the file system to be converted:
# umount mount_point
