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

Beginning with version 4U6 of the software, disk archiving can also be carried out

on the Sun StorageTek 5800 system. The Sun StorageTek 5800 is an online storage

appliance with an integrated hardware and software architecture in which the disk-

based storage nodes are arranged in a symmetric cluster.The media abbreviation for

Sun StorageTek 5800 disk archives in the vsns directives is cb.

■ The clients and endclients directives. If you archive files from a client host

to a server host, the server system must have a diskvols.conf file that contains

the name of the client system. The format for these directives is shown in

CODE EXAMPLE 3-35.

For client-system, specify the host name of the client system that contains the

source files.

■ The -recycle_minobs percent recycler directive. This option is used to set a

threshold, 50 percent by default, for the recycler’s rearchiving process for disk

archives. When the percentage of obsolete files within an archived tar file on the

disk reaches this threshold, the recycler begins moving the valid files from the

archive into a new tar file. When all of the valid files have been moved, the

original tar file is marked as a candidate for removal from the disk archive. This

option is ignored for removable media recycling.

■ The following recycling directives are ignored for disk archive recycling:

■ recycle_hwm

■ recycle_vsncount
