shrink.cmd - Oracle HSM shrink command file
∕etc∕opt∕SUNWsamfs∕shrink.cmd
SUNWsamfs
Directives for controlling the shrink
can be read from the
∕etc∕opt∕SUNWsamfs∕shrink.cmd
file.
The directives must appear one per line.
Comment lines are permitted. Comment lines must begin with a
pound character (#
), and the comment can extend through the
rest of the line.
Directives that appear prior to any fs=
directive
are applied to all file systems.
Directives that appear after a fs=
directive are applied
to the specified file system only.
Directives that are specific to a file system override general
directives.
The miscellaneous directives control whether a log file is written, whether to stage back on-line files that were released, other aspects of shrinking.
The following miscellaneous directives can be specified in
the shrink.cmd
file:
block_size =
nSets the buffer size to read the .inodes file in units of megabytes. For n, specify an integer such that 1 ≤ n ≤ 16. The default n=1MB.
display_all_files
Writes the name for each file, as it is encountered, to the log file. This directive allows you to see the result of executing the remove or release command. By default, the file names are not displayed to the log file.
do_not_execute
Writes the name for each file, as it is encountered, to the log file. This directive allows you to judge the effects of executing the remove or release command, without actually executing the command. By default, the command is executed.
fs =
file_system_family_set_name Specifies to the shrink that the subsequent directives apply to the indicated file_system_family_set_name only.
logfile =
filename Sets the name of the shrink's log file to filename. By default, no log file is written.
stage_files
The files released are staged back on-line. By default, released files are not staged back on-line. See stage.
stage_partial
The partial size released for files is staged back on-line. By default, the partial size is not staged back on-line. See stage -p.
streams =
nSets the number of threads to be used to shrink the equipment. For n, specify an integer such that 1 ≤ n ≤ 128. The default n=8.
Example 1. This
example file sets the streams
directive for
the samfs1
file system. A shrink log is produced.
fs = samfs1 streams = 64 logfile = ∕var∕adm∕shrink.log
Example 2. This example specifies stage parameters and log files for each file system.
display_all_files logfile = ∕var∕adm∕default.shrink.log fs = samfs1 stage_files stage_partial logfile = ∕var∕adm∕samfs1.shrink.log fs = samfs2 stage_partial logfile = ∕var∕adm∕samfs2.shrink.log
