Diagnostic and Maintenance Functions
The drive can:
• Run diagnostics
• Test write and read functions
• Test a suspect tape cartridge
• Update firmware
• Perform other diagnostic and maintenance functions
The drive must be in maintenance mode to perform these functions.
Caution: Maintenance functions cannot be performed concurrently
with read or write operations. While in maintenance mode,
the tape drive does not accept host interface commands
from the server.
Table 5 on page 45 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.
