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 must be backed up and replaced.
Formatting the disk does not improve the availability of spare sectors.
You can run this task directly from the AIX command line. See the following command syntax:
diag -c -d
deviceName
-T chkspares
