Tivoli Storage Manager for Windows: Administrator's Reference
Use this command to check for inconsistencies between database information
and a storage pool volume. |You can only audit volumes that belong to storage pools with
|DATAFORMAT=NATIVE. During the audit, the server sends processing information to the
activity log and the server console.
While an audit process is active, clients cannot restore data from the
specified volume or store new data to that volume.
If the server detects a file with errors, handling of the file will depend
on the type of storage pool to which the volume belongs, whether the FIX
option is specified on this command, and whether the file is also stored on a
volume assigned to other pools.
You cannot audit a volume if it is being deleted from a primary or copy
storage pool.
If TSM does not detect errors for a file that was marked as
damaged, the state of the file is reset so that the file can be
used.
To display information about the contents of a storage pool volume, use the
QUERY CONTENT command.
This command creates a background process that can be canceled with the
CANCEL PROCESS command. To display information on background processes,
use the QUERY PROCESS command.
Privilege Class
To issue this command, you must have system privilege, unrestricted storage
privilege, or restricted storage privilege for the storage pool to which the
volume is defined.

Parameters
- volume_name (Required)
- Specifies the name of the storage pool volume you want to audit.
- Fix
- Specifies how TSM resolves inconsistencies between the database inventory
and the specified storage pool volume. This parameter is
optional. The default is NO.
The actions TSM performs depend on whether the volume is assigned to a
primary or a copy storage pool.
Primary Storage Pool:
- Note:
- If the AUDIT VOLUME command does not detect an error in a file that was
previously marked as damaged, TSM resets the state of the file so that it can
be used. This provides a means for resetting the state of damaged files
if it is determined that the errors were caused by a correctable hardware
problem such as a dirty tape head.
- Fix=No
- TSM reports, but does not delete, database records that refer to files
with inconsistencies:
- TSM marks the file as damaged in the database. If a
backup copy is stored in a copy storage pool, you can restore the file using
the RESTORE VOLUME or RESTORE STGPOOL command.
- If the file is a cached copy, you must delete references to the file on
this volume by issuing the AUDIT VOLUME command and specifying FIX=YES.
If the physical file is not a cached copy, and a duplicate is stored in a copy
storage pool, it can be restored by using the RESTORE VOLUME or RESTORE
STGPOOL command.
- Fix=Yes
- TSM fixes any inconsistencies as they are detected:
- If the physical file is a cached copy, TSM deletes the database records
that refer to the cached file. The primary file is stored on another
volume.
- If the physical file is not a cached copy, and the file is also stored in
one or more copy storage pools, the error will be reported and the physical
file marked as damaged in the database. You can restore the physical
file by using the RESTORE VOLUME or RESTORE STGPOOL command.
- If the physical file is not a cached copy, and the physical file is not
stored in a copy storage pool, each logical file for which inconsistencies are
detected are deleted from the database.
- Note:
- Do not use the AUDIT VOLUME command with FIX=YES if a restore process
(RESTORE STGPOOL or RESTORE VOLUME) is running. The AUDIT VOLUME
command could cause the restore to be incomplete.
Copy Storage Pool:
- Fix=No
- TSM reports the error and marks the physical file copy as
damaged in the database.
- Fix=Yes
- TSM deletes any references to the physical file and any database records
that point to a physical file that does not exist.
- SKIPPartial
- Specifies whether TSM ignores skipped files, which are files that span
multiple storage pool volumes. This parameter is optional. The
default value is NO. When performing an audit operation on a sequential
access media volume, this parameter prevents additional sequential access
media mounts that may be necessary to audit any skipped
files. Possible values are:
- No
- TSM audits files that span multiple volumes.
Unless you specify SKIPPARTIAL=YES, TSM attempts to process each file
stored on the volume, including files that span into and out of other
volumes. To audit files that span multiple volumes, the following
conditions must be true:
- For sequential access volumes, the additional sequential access volumes
must have an access mode of read/write or
read-only.
- For random access volumes, the additional volumes must be online.
- Yes
- TSM audits only files that are stored on the volume to be audited.
The status of any skipped files is unknown.
- Quiet
- Specifies whether TSM sends detailed informational messages to the
activity log and the server console about irretrievable files on the
volume. This parameter is optional. The default is NO.
Possible values are:
- No
- Specifies that TSM sends detailed informational messages and a
summary. Each message contains the node, file space, and client name
for the file.
- Yes
- Specifies that TSM sends only a summary report.
Examples
Task
Verify that the database information for storage pool volume PROG2 is
consistent with the data stored on the volume. TSM fixes any
inconsistencies.
- Command:
- audit volume prog2 fix=yes
