ABSTRACT:
SCSI commands are used over IP (iSCSI) to trigger digest calculations of block span ranges. The parameters of the digest-calculation command include the command itself a block range, and the digest-calculation method to be used. A related combined command compares the digest-calculation result with a preexisting digest-calculation result. The parameters of the combined command include the parameters of the digest-calculation command, and the preexisting digest calculation result. Another command initializes a block range.
