Chapter 2 Using Automated Libraries and Manually Loaded Drives 13

If removable media operations are already running when the preceding command is

entered, the following message is generated:

For more information about the samd(1M) command, see the samd(1M) man page.

▼ To Stop Removable Media Operations

It is possible to stop removable media operations and leave the Sun StorageTek SAM

system mounted. You might do this, for example, if you want to manually

manipulate cartridges in a library. When operations are restarted, pending stages are

reissued and archiving is resumed.

● Use the samcmd(1M) idle and samd(1M) stop commands.

For eq, enter the equipment ordinal of the drive being stopped as defined in the mcf

file. To idle multiple drives, enter a samcmd idle eq command for each drive

configured in your mcf file.

You can also idle drives by using the samu(1M) operator utility or by using File

System Manager.

Note – Idle the drives in your Sun StorageTek SAM environment before issuing the

samd(1M) stop command. This enables the archiver, stager, and other processes to

complete current tasks. Failure to issue the samd(1M) stop command can cause

unexpected results when archiving, staging, and other activities are resumed.

▼ To Turn On an Automated Library

When a library is in the on state, it is under the control of the Sun StorageTek SAM

system and can proceed with general operations. When you turn on a library, the

Sun StorageTek SAM software performs the following actions:

■ Queries the device regarding its internal state. It discovers where tapes are,

whether or not barcodes are used, and so on.

■ Updates the catalog and other internal structures.
