Minimum Hardware and Software Requirements for Using DIV in SAM-QFS
The tpverify command uses the SCSI Verify command with the DIV/DADP feature of the StorageTek T10000C tape drive to verify media.
The tpverify command loads the specified volume into a tape drive and verifies it. If the device is not specified, then the volume is loaded into an available drive in the media changer. The SAM-QFS file system chooses the drive into which the volume is loaded. You can cancel a verify operation if the resource is needed. If the tpverify command is canceled, then the last verified position (LVPos) is saved in the catalog as the starting position for the next verify operation.
Note - A verify operation on a tape drive that is in the “on” state can be cancelled by the SAM-QFS archiver or stager if the resource is needed. Use a drive in the “unavail” state to avoid the verify operation cancellation by SAM-QFS.
The tpverify command can be used with a non-DIV tape drive as long as the tape drive supports the SCSI Verify command in fixed block with a block count of either 0x1000, 0x100, or 0xff. For example, the HP LTO-4 tape drives support the SCSI Verify command and a block count of 0xff. The SCSI Verify errors for the non-DIV tape drives are handled the same way as the DIV media errors, in that the tpverify command sets bad media and terminates the verify run. Check the /var/opt/SUNWsamfs/devlog/eqord file for failure details.
The following table shows the options that are available for the tpverify command.

For more information about the tape verify command, see the tpverify(1M) man page.

Example 13-4 Examples of Using the tpverify Command
The following examples show how to apply the tpverify command.
To load VSN CET050 into an available drive:
# tpverify ti.CET050
To load VSN CET048 into drive 31 and wait for the results:
# tpverify -w -a ti.CET048 31; echo $?
To cancel a verify run on VSN CET048 and wait for the results:
# tpverify -w -c ti.CET048 31; echo $?
