5.4 Testing DSSI Storage Devices
If the ISE is connected to its front panel, you must install a bus node ID plug
in the corresponding socket on the front panel. If the ISE is not connected to
its front panel, it reads the bus node ID from the three-switch DIP switch on
the side of the drive.
DSSI storage devices contain the following local programs:
DIRECT A directory, in DUP specified format, of available local programs
DRVTST A comprehensive drive functionality verification test
DRVEXR A utility that exercises the ISE
HISTRY A utility that saves information retained by the drive, including the
internal error log
ERASE A utility that erases all user data from the disk
VERIFY A utility that is used to determine the amount of ‘‘margin’’ remaining in
on-disk structures.
DKUTIL A utility that displays disk structures and disk data.
PARAMS A utility that allows you to look at or change drive status, history,
parameters, and the internal error log
Use the SET HOST/DUP command described in Section 5.4.1 to access the
local programs listed above. Example 5–17 provides an abbreviated example of
running DRVTST for an ISE (Bus node 2 on Bus 0).
Caution
When running internal drive tests, always use the default (0 = No)
in responding to the "Write/read anywhere on medium?" prompt.
Answering yes could destroy data.
Example 5–18 provides an abbreviated example of running DRVEXR for an
ISE (Bus node 2 on Bus 0).
Caution
When running internal drive tests, always use the default (0 = No)
in responding to the ‘‘Write/read anywere on medium?’’ prompt.
Answering yes could destroy data.
