Verifying, diagnosing, and maintaining the system 6–16
The syntax of the command is as follows:
all_ost_raw_lun_check.bash [-h] | [-v] [-r path] [-f filesystem] -s|-p
Where:
-r --raw_lun_check path
Specifies a path other than the default path for the
raw_lun_check.bash
command.
-f --filesystem filesystem
Specifies that only the OST LUNs in the specified file
system are to be tested. If no file system is specified, all
OST LUNs used in file systems are tested.
-s --serial
Specifies that the test is to be run on each LUN serially
across all appropriate Object Storage Servers.
-p --parallel
Specifies that the test is to be run on each LUN in parallel
across all appropriate Object Storage Servers.
-h --help
Displays help on the command.
-v --verbose
Provides verbose output.
The default mode of operation is to run the test in parallel on each appropriate Object Storage Server.
Before you run the command, you must stop any file systems that are using the LUNs that are to be tested.
The command only tests LUNs that are not being actively used as part of a running file system.
Compare the results of the test with the expected performance details provided in Appendix B.
Example 6-1 shows a test of the performance of the LUNs being used in the
data
file system.
