Cycle times for cleaning cartridges are as follows.

 

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. 

Optimizing Tape Drive Performance

13

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.
