Dismount the volume (see Section 3.9, “Dismounting a Traditional Volume,” on page 21 ), then use
the Vrepair utility to correct volume problems or to remove name space entries from File Allocation
Tables (FATs) and Directory Entry Tables (DETs).
You can run the Vrepair utility (
vrepair
) on a damaged volume while other volumes are mounted.
For details about using the Vrepair utility, see “ VREPAIR ” in the OES 2: Utilities Reference .
Following are typical instances when the Vrepair utility can help:
Š
A hardware failure either prevented a volume from mounting or caused a disk read error.
NOTE: Although the Vrepair utility cannot fix hardware problems, it can sometimes fix
related volume damage.
Š A power failure caused a corrupted volume.
Š
The server console displays a mirroring error when the server boots.
This mirroring refers to the two copies of FATs and DETs that the operating system keeps (if
disks are mirrored, NetWare keeps four copies).
If a volume fails to mount as the server is booting, the Vrepair utility loads automatically and
attempts to repair the volume.
When the Vrepair utility autoloads, it uses the default options. If you want to use an alternate option,
load the Vrepair utility manually and set the alternate option before running the Vrepair utility.
NOTE: If you do not want the Vrepair utility to automatically repair a volume that fails to mount,
use the “ SET ” parameter named Automatically Repair Bad Volumes to change the default value of
On to Off.
3.18.1 Prerequisites
‰ The volume you want to repair must be dismounted. For instructions, see Section 3.9,
“Dismounting a Traditional Volume,” on page 21 .
‰
If the volume to be repaired has name space support, the corresponding Vrepair name space
module (
v_ namespace .nlm
) must be located in either the
sys:\system
directory or in a
search path directory.
Example modules include
v_mac.nlm
and
v_long.nlm
.
3.18.2 Procedure
1 At the server console prompt, enter
vrepair [ volume_name ] [ logfile_name ]
Replace
volume_name
with the name of the volume to repair. If there is only one volume that
is dismounted, you don’t need to specify this parameter, because the Vrepair utility attempts to
repair that volume.
If you want to save the error log, replace the logfile_name with the name of the file you
want the Vrepair utility to create. The Vrepair utility creates a log of errors it finds. It displays
the errors on screen and writes them to a file if you specify a filename.
