a. These times are accurate to ± 20 seconds.
On the last (20th) pass, the cleaning process completes and the cleaning
media is rewound, but the cleaning cartridge is not ejected. You must
manually eject the cartridge.
If the cleaning cartridge is loaded again after the 20th pass, it winds all
the way to the end of the cartridge and back again without performing
the cleaning sequence, and the cleaning cartridge does not eject. You
must manually eject the cartridge.
Many factors contribute to tape drive performance. Host system
considerations include processor speed, block size, host adapter
performance, host bus configurations, and software.
If you are concerned about the performance of the tape drive, check the
following:
• Ensure that the tape drive is properly defined for the host system.
If the tape drive is not defined within the system, the host adapter
does not interact well with the tape drive.
• Ensure that the host bus adapter card and the SCSI bus are operating
in Ultra320 mode.
