Spare Sector Availability
This selection checks the number of spare sectors available on the optical disk. The
spare sectors are used to reassign when defective sectors are encountered during
normal usage or during a format and certify operation. Low availability of spare sectors
indicates that the disk needs to be backed up and replaced. Formatting the disk does
not improve the availability of spare sectors.
This task can be run directly from the AIX command line. The syntax of the command is
as follows:
diag -c -d deviceName -T chkspares
SSA Service Aid
This service aid provides tools for diagnosing and resolving problems on SSA-attached
devices. The following tools are provided:
v Set Service Mode
v Link Verification
v Configuration Verification

System Fault Indicator
This task is used to display or reset the system fault indicator on systems that support
this function. This task is also used to set the system fault indicator for testing
purposes, but the system fault indicator is set back to Normal when you exit this task.
The system fault indicator is used to identify a fault with the system. This indicator is set
automatically by hardware firmware, or diagnostics when a fault is detected in the
system.
The system fault indicator is turned off when a Log Repair Action is performed. After a
serviceable event is complete, do a System Verification to verify the fix. At this time,
also do a Log Repair Action if the test on the resource was good and that resource had
an entry in the error log.
Display a usage statement and/or return code. If the -c flag is present, only the
return code displays to indicate the service aid did not run. If the -c is not
used, a usage statement displays and the service aid exits.
Display or copy log sense information.
Display time since drive was last cleaned.
Copy trace table.
Verbose mode. If the -c flag is present, the information displays on the screen.
If the -n flag is present, the information about tape-head cleaning is printed.
