Configuring MSDP data integrity checking behavior

NetBackup performs several data integrity checks. You can configure the behavior of the integrity checks.

Two methods exist to configure MSDP data integrity checking behavior, as follows:

Warning:

Veritas recommends that you do not disable the data integrity checking. If you do so, NetBackup cannot find and repair or report data corruption.

To configure data integrity checking behavior by using a command

To configure behavior, specify a value for each of the data integrity checks, as follows:

Data consistency checking. Use the following commands to configure behavior:

Enable

UNIX: /usr/openv/pdde/pdcr/bin/pddecfg - a enabledataintegritycheck

Windows: install_path\Veritas\pdde\pddecfg - a enabledataintegritycheck

Disable

UNIX: /usr/openv/pdde/pdcr/bin/pddecfg - a disabledataintegritycheck

Windows: install_path\Veritas\pdde\pddecfg - a disabledataintegritycheck

Get the status

UNIX: /usr/openv/pdde/pdcr/bin/pddecfg - a getdataintegritycheck

Windows: install_path\Veritas\pdde\pddecfg - a getdataintegritycheck

Cyclic redundancy checking. Use the following commands to configure behavior:

Enable	CRC does not run if queue processing is active or during disk read or write operations. UNIX: `/usr/openv/pdde/pdcr/bin/crcontrol --crccheckon` Windows: `install_path\Veritas\pdde\Crcontrol.exe --crccheckon`
Disable	UNIX: `/usr/openv/pdde/pdcr/bin/crcontrol --crccheckoff` Windows: `install_path\Veritas\pdde\Crcontrol.exe --crccheckoff`
Enable fast checking	Fast check CRC mode begins the check from container 64 and does not sleep between checking containers. When the fast CRC ends, CRC behavior reverts to the behavior before fast checking was invoked. UNIX: `/usr/openv/pdde/pdcr/bin/crcontrol --crccheckrestart` Windows: `install_path\Veritas\pdde\Crcontrol.exe --crccheckrestart`
Get the status	UNIX: `/usr/openv/pdde/pdcr/bin/crcontrol --crccheckstate` Windows: `install_path\Veritas\pdde\Crcontrol.exe --crccheckstate`

To configure data integrity checking behavior by editing the configuration files

Use a text editor to open the contentrouter.cfg file or the spa.cfg file, which control the data integrity checking behavior.
The files reside in the following directories:
- UNIX: storage_path/etc/puredisk
- Windows: storage_path\etc\puredisk
To change a parameter, specify a new value.
Save and close the file.
Restart the NetBackup Deduplication Engine and the NetBackup Deduplication Manager.
You can do this from the Daemons tab in the Activity Monitor.
