For more information about the chmed(1M) command, see the chmed(1M) man

page.

▼ To Reset the Number of Cleaning Cycles

Cleaning tapes are useful only for a limited number of cleaning cycles. You can view

the number of remaining cycles with the samu(1M) utility’s :v display or by using

File System Manager.

The Sun StorageTek SAM system tracks the number of cleaning cycles used for each

cleaning tape and ejects the tape when the number of remaining cycles equals zero.

For example, a DLT cleaning tape has 20 cycles, and an Exabyte cleaning tape has 10

cycles. Each time a cleaning tape is imported, the cleaning cycle is reset to the

highest number of cycles for that type of tape.

If automatic cleaning is available on your system but all cleaning tapes in the

automated library have a count of zero, the drive is set to off and a message is issued

in the Sun StorageTek SAM log.

● Use the chmed(1M) command to reset a cleaning tape with a count of zero.

▼ To Limit the Number of Cleaning Cycles

Certain drive errors can result in the repeated loading of cleaning cartridges until all

cleaning cycles are consumed.

● Use the chmed(1M) command to limit the number of cleaning cycles on cleaning

cartridges.

For eq, specify the equipment ordinal of the automated library. For slot, specify the

slot in which the cleaning cartridge has been loaded.
