Diagnostic and Maintenance Functions
The drive can:
v Run diagnostics
v Test write and read functions
v Test a suspect tape cartridge
v Update its own firmware
v Perform other diagnostic and maintenance functions
The drive must be in maintenance mode to perform these functions.
Attention: Maintenance functions cannot be performed concurrently with read or
write operations. While in maintenance mode, the tape drive does not accept SCSI
commands from the server. The tape drive does accept LDI or RS-422 commands.
Table D-10 describes each diagnostic and maintenance function that the drive can
perform, gives the function code which appears on the Single-character Display
(SCD), and directs you to the instructions for performing the function. It is
recommended that you use a customer-supplied scratch (blank) data cartridge for
diagnostic testing.
