AUDIT VOLUME (Verify database information for a storage pool volume)
Use this command to check for inconsistencies between database information and a storage pool volume. Processing information generated during an audit is sent to the activity log and server console.
You cannot audit a volume if it is being deleted from a primary or copy storage pool.
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.
If IBM Spectrum Protect does not detect errors for a file that was marked as damaged, the state of the file is reset so that it can be used.
The server will not delete archive files that are on deletion hold. If archive retention protection is enabled, the server will not delete archive files whose retention period has not expired.
To display information about the contents of a storage pool volume, use the QUERY CONTENT command.
To audit multiple volumes, you can use the FROMDATE and TODATE parameters. Use the STGPOOL parameter to audit all volumes in a storage pool. When you use the parameters FROMDATE, TODATE, or both, the server limits the audit to only the sequential media volumes that meet the date criteria, and automatically includes all online disk volumes in storage. To limit the number of volumes that may include disk volumes, use the FROMDATE, TODATE, and STGPOOL parameters.
If you are running a server with archive retention protection enabled, and you have data stored in storage pools which are defined with the parameter RECLAMATIONTYPE=SNAPLOCK, the Last Access Date on the NetApp SnapLock Filer for a volume should be equal to the End Reclaim Period date that you see when you issue a QUERY VOLUME F=D command on that volume. During AUDIT VOLUME processing, these dates are compared. If they do not match and the AUDIT VOLUME command is being run with the FIX=NO parameter, a message will be issued to you indicating that the command should be run with the FIX=YES parameter to resolve the inconsistency. If they do not match and the AUDIT VOLUME command is being run with the FIX=YES parameter, the inconsistencies will be resolved.
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.
Syntax
Parameters
- volume_name
- Specifies the name of the storage pool volume you want to audit. This parameter is required if you do not specify a storage pool. You cannot specify a volume name together with the FROMDATE and TODATE parameters.
- Fix
- Specifies how the server resolves inconsistencies between the
database inventory and the specified storage pool volume. This parameter
is optional. The default is NO.
The actions the server 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, IBM Spectrum Protect 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
- IBM
Spectrum Protect reports,
but does not delete, database records that refer to files with inconsistencies:
- IBM Spectrum Protect 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
- The server fixes any inconsistencies as they are detected:
- If the physical file is a cached copy, the server 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.
- If archive retention protection is enabled by using the SET ARCHIVERETENTIONPROTECTION command, a cached copy of data can be deleted if needed. Data in primary and copy storage pools can only be marked damaged and never deleted.
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
- The server reports the error and marks the physical file copy as damaged in the database.
- Fix=Yes
- The server deletes any references to the physical file and any database records that point to a physical file that does not exist.
- SKIPPartial
- Specifies whether IBM
Spectrum Protect ignores partial 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 partial files. Possible values
are:
- No
- IBM
Spectrum Protect audits files that span multiple
volumes. Unless you specify SKIPPARTIAL=YES, IBM Spectrum Protect 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
- IBM Spectrum Protect audits only files that are stored on the volume to be audited. The status of any partial files is unknown.
- Quiet
- Specifies whether IBM
Spectrum Protect 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 IBM Spectrum Protect sends detailed informational messages and a summary. Each message contains the node, file space, and client name for the file.
- Yes
- Specifies that IBM Spectrum Protect sends only a summary report.
- FROMDate
- Specifies the beginning date of the range to audit volumes. The
default is the current date. All sequential media volumes meeting
the time range criteria that were written to after this date are audited.
The server includes all online disk volumes in storage. The server
starts one audit process for each volume and runs the process serially.
You cannot use this parameter if you have specified a volume. This
parameter is optional. To limit the number of volumes that may include
disk volumes, use the FROMDATE, TODATE, and STGPOOL parameters. You can specify the date by using one of the following values:
Value Description Example MM/DD/YYYY A specific date 10/15/2001 If a date is entered, all candidate volumes written on that day (starting at 12:00:01 am) will be evaluated.
TODAY The current date TODAY TODAY-days or -days The current date minus days specified. The maximum number of days you can specify is 9999. TODAY –7 or –7. To display information beginning with volumes written a week ago, you can specify FROMDATE=TODAY-7 or FROMDATE= -7.
EOLM (End Of Last Month) The last day of the previous month. EOLM EOLM-days The last day of the previous month minus days specified. EOLM-1 To include files that were active a day before the last day of the previous month.
BOTM (Beginning Of This Month) The first day of the current month. BOTM BOTM+days The first day of the current month, plus days specified. BOTM+9 To include files that were active on the 10th day of the current month.
- TODate
- Specifies the ending date of the range for volumes to audit. All
sequential media volumes meeting the time range criteria that were
written to before this date are audited. The server includes all
online disk volumes in storage. If you do not specify a value, the
server defaults to the current date. You cannot use this parameter
if you have specified a volume. This parameter is optional. To limit
the number of volumes that may include disk volumes, use the FROMDATE,
TODATE, and STGPOOL parameters. You can specify the date by using one of the following values:
Value Description Example MM/DD/YYYY A specific date 10/15/2001 If a date is entered, all candidate volumes written on that day (ending at 11:59:59 pm) will be evaluated.
TODAY The current date TODAY TODAY-days or -days The current date minus days specified. The maximum number of days you can specify is 9999. TODAY–1 or –1. To display information created up to yesterday, you can specify TODATE=TODAY-1 or simply TODATE= -1.
EOLM (End Of Last Month) The last day of the previous month. EOLM EOLM-days The last day of the previous month minus days specified. EOLM-1 To include files that were active a day before the last day of the previous month.
BOTM (Beginning Of This Month) The first day of the current month. BOTM BOTM+days The first day of the current month, plus days specified. BOTM+9 To include files that were active on the 10th day of the current month.
- STGPool
- This parameter specifies that the server only audits the volumes from the specified storage pool. This parameter is optional. You cannot use this parameter if you have specified a volume.
Example: Verify database information for a specific storage pool volume
Verify that the database information for storage pool volume PROG2 is consistent with the data stored on the volume. IBM Spectrum Protect fixes any inconsistencies.audit volume prog2 fix=yes
Example: Verify database information for all volumes written to during a specific date range
Verify that the database information for all eligible volumes written to from 3/20/2002 to 3/22/2002 is consistent with data stored on the volume.audit volume fromdate=03/20/2002 todate=03/22/2002
Example: Verify database information for all volumes in a specific storage pool
Verify that the database information for all volumes in storage pool STPOOL3 is consistent with data stored on the volume for today.audit volume stgpool=STPOOL3
Example: Verify database information for all volumes in a specific storage pool written to in the last two days
Verify that the database information for all volumes in storage pool STPOOL3 is consistent with data stored on the volume for the last two days.audit volume stgpool=STPOOL3 fromdate=-1
