Chapter 2 Using Automated Libraries and Manually Loaded Drives 23

To invoke the legacy Sun StorageTek SAM auto-cleaning feature, which relies on

sense data only for drive cleaning status, insert the following line in the

defaults.conf file:

Note – When using the auto-cleaning feature with a library with more than two

drives, it is recommended that you have at least two cleaning cartridges per Sun

StorageTek SAM catalog. If there are drives that need to be cleaned, and not enough

cleaning cartridges, those drives will be put into a DOWN state.

▼ To Clear Media Errors

When a hardware or software error is encountered on a cartridge, the Sun

StorageTek SAM system sets the media error flag in the VSN catalog. On any

given cartridge that generates a media error signal, you can use the chmed(1M)

command to clear the error, and you can then attempt to use the cartridge. The

media error flag is displayed in the samu(1M) utility’s v display and in File System

Manager.

Note – Removing the error flag can cause problems. If you are not confident that

you know what caused the error and that the flag can safely be removed, contact

Sun Technical Support first.

1. Use the chmed(1M) command to clear the media error flag.

2. Issue the auditslot(1M) command to update the space remaining information.
