information returned by the drive. The possible address formats are as
follows:
Format Description

Logical block address
msf

The syntax of a command that uses the address-format parameter is as
follows:
scu>
[ command][address-format{ lba| msf}]
The nexus-information parameter lets users specify values to override
the bus, target, and LUN values normally taken from the selected SCSI
device. The
nexus-information keywords are as follows:
Parameter Description
bus (pid) R:0-3
SCSI bus number (path ID)
target (tid) R:0-7
SCSI target number (target ID)
lun R:0-7
SCSI Logical Unit Number (LUN)
You use the test-parameter variables to specify the physical limits of the
media on which the command can operate. For example, these may be the
starting and ending logical block numbers on a disk. The test parameters
for a command use the following syntax:
scu> command
[ media-limits][test-control]
The media-limits parameter, which controls the media tested, has the
following syntax:
{lbn } { length n }
scu> command [{ starting n }] [{ endingn }] [size n]
