134 Sun StorageTek SAM Archive Configuration and Administration Guide Version 4, Update 6, 04/07
The rest of this section describes the stager directives. For additional information on
stager directives, see the stager.cmd(4) man page.
The “Example stager.cmd File” on page 139 shows the completed stager.cmd
file after all possible directives have been set.
Note If you are using the File System Manager software, you can control staging
from the File System Summary or File System Details page. You can browse the file
system and see the status of individual files, use filters to view certain files, and
select specific files to stage. You can select which copy to stage from or let the system
choose the copy.
To set stager directives, you use vi(1) or another editor to edit the
/etc/opt/SUNWsamfs/stager.cmd file. You then use the samd(1M) command
with its config option to propagate the file changes and restart the system:
For information on the directives you can include in this file, see the following
subsections:
“The drives Directive: Specifying the Number of Drives” on page 134
“Setting the Stage Buffer Size” on page 135
“Specifying a Log File” on page 136
“Specifying the Number of Stage Requests” on page 139
The drives Directive: Specifying the Number of
Drives
By default, the stager uses all available drives when staging files. If the stager keeps
all the drives busy, this can interfere with the archiver’s activities. The drives
directive specifies the number of drives available to the stager. This directive has the
following format:
# samd config
drives = library count
