Chapter 6 Recycling 151

Before configuring the recycler, note the following:

■ Directives in the archiver.cmd file control recycling by archive set. Directives in

the recycler.cmd file control recycling by library. In addition, the

recycler.cmd file controls general recycler behavior. For information on

recycler directives, see “Using Recycling Directives” on page 152.

■ Do not recycle volumes that contain removable media files. You create removable

media files by using the request(1) command. A volume with removable media

files can never be drained.

■ Do not run the recycler while performing maintenance on a Sun StorageTek SAM

file system. The recycler uses the .inodes file and the mcf file to help identify

files that are current or expired and the devices associated with a file system.

Absence of proper information in the .inodes and mcf files can cause current

archived data to appear as expired and be recycled.

■ All Sun StorageTek SAM file systems must be mounted when the recycler is run.

If you are recycling from online disk, the file system that contains the disk

volumes must be mounted and the host system must be accessible.

Caution – Extreme care must be taken when configuring the recycler if you are

using disk archiving in an environment with multiple SAM-QFS servers. The

diskvols.conf file for each SAM-QFS server must point to a unique set of disk

volume resource specifications (disk archiving target directories). If any of these are

shared between different SAM-QFS servers, then running the recycler from one

SAM-QFS server will destroy the disk archive data that is being managed by the

other SAM-QFS server.

The recycler is not enabled by default. You must initiate recycling by entering the

sam-recycler(1M) command.
