For example, the following command sets the cleaning cycle count to 20 for the

cleaning cartridge in slot 77 of the automated library with the equipment ordinal of

50.

▼ To Clean a Tape Drive

When automatic cleaning is not available and the system uses barcodes, perform the

following procedure to request manually that a drive be cleaned:

● Use the cleandrive(1M) command.

For eq, specify the equipment ordinal of the automated library as defined in the mcf

file. This is the drive to be loaded with the cleaning cartridge.

Tape Drive Auto-Cleaning

Beginning with Sun StorageTek SAM 4U4, the default setting for software-initiated

tape drive cleaning is off, which forces the user to choose between a hardware-

initiated or software-initiated tape drive cleaning strategy.

A hardware-initiated cleaning strategy uses the media changer’s built-in auto-

cleaning feature.

■ In order to use this feature, you may need to put cleaning cartridges in special

slots.

■ See the manufacturer's documentation for directions.

A software-initiated cleaning strategy uses the Sun StorageTek SAM auto-cleaning

feature.

■ The logsense option is an enhancement to this feature that prevents a drive

from using expired cleaning media.

■ For the Sun StorageTek SAM auto-cleaning feature to be enabled, the hardware-

initiated cleaning should be disabled and the following line should appear in the

defaults.conf file:

# chmed -count 20 50:77

cleandrive eq

tapeclean = all autoclean on logsense on

1 2 ... 41 42 43 44 45 46 47 48 49 50 51 ... 287 288
