Logical volume "/dev/vg01/logvolmir" has been
successfully extended.
The -m option specifies that the system maintains one mirror of the
data in logical volume /dev/vg01/logvolmir. The /dev/rz2g
argument specifies that the system maintain the mirror using physical
extents on the /dev/rz2g physical device.
5. Create a file system on the logvolmir volume by using the newfs
command:
# newfs /dev/vg01/logvolmir rz56
6. Mount the ULTRIX file system on the LVM mirrored logical device and
restore the file system from tape:
# mount /dev/vg01/logvolmir /fs
# cd /fs
# restore -r
The mount command mounts the /dev/vg01/logvolmir logical
volume on the /fs directory. The cd command changes the current
directory to /fs, and the restore -r command restores the ULTRIX
data from tape to the current working directory.
The /fs file system is now converted to DIGITAL UNIX LVM disk
mirroring.
5.3 Using the tar and pxtar Commands
The ULTRIX system supports two commands for maintaining tape
archives: pxtar and tar. The pxtar command is POSIX-compliant; the
tar command is not.
The DIGITAL UNIX system has one tape archive command, tar. The
DIGITAL UNIX tar command is POSIX-compliant.
If you use the ULTRIX pxtar command to create a tape archive, you can
read that tape archive by using the DIGITAL UNIX tar command. In
addition, if you use the ULTRIX tar command to create archives that fit
on a single volume, you can read those single-volume archives with the
DIGITAL UNIX tar command.
However, the ULTRIX tar command allows you to create and read an
archive that can span multiple tapes. The ULTRIX tar command writes a
file header at the start of each continuation tape. By default, the DIGITAL
UNIX tar command does not expect the ULTRIX header information. The
header information is treated as data, resulting in an incorrectly extracted
