190 Sun StorageTek SAM Archive Configuration and Administration Guide • Version 4, Update 6, 04/07

The directives shown in CODE EXAMPLE 7-17 do the following:

■ The -recycle_hwm directive sets the library’s high-water mark for the archive

set. When the utilization of the VSNs exceeds this percentage, recycling of the

archive set begins.

■ The -recycle_ignore directive is inserted only temporarily. This directive

prevents recycling from occurring until you have configured and tested your

environment. You can remove this directive in a later step.

■ The -recycle_mingain directive is set high to ensure efficiency by limiting the

amount of work needed to regain space.

■ The -recycle_vsncount 1 directive specifies that the recycler drain one VSN at

a time. When the first VSN is drained, a second is selected to begin draining. At

any given moment, there is one VSN in the queue to be relabeled and one VSN in

the queue to be drained. As a result, recycling does not overwhelm the system.

3. Edit the recycler.cmd file on the client and specify a log file to receive recycling

log output.

CODE EXAMPLE 7-18 shows the recycler.cmd file on client zeke, which has been

edited to specify a recycler log file.

# Remote directives.

# Start with mingain high to reduce workload.

# If you need more recycling, reduce mingain.

# If too much recycling, increase High-Water Mark.
