HP StorageWorks 9100 Extreme Data Storage System administration guide V1.0.2 (AN540-96018, February 2010)

3. Start the HP ExDS9100 CLI by entering the exdsmgr command
Running exdsmgr commands
In exdsmgr commands where it is appropriate, you can use either the singular or the plural form of
the component to which the command applies. For example, you can enter the show lun command
in either of the following formats:
ExDS> show lun
ExDS> show luns
All of the commands, except for the help command, can be abbreviated. For example, you can
abbreviate the exds> show lun command as follows:
ExDS>show lu
You must enter enough letters to make the abbreviated command unique; otherwise, the command
will not work (the usage for the command will be displayed). For example, in show commands, you
cannot abbreviate the word show to sh, as this could be confused with the shutdown command;
you can, however, abbreviate it to sho. In interactive mode, command completion is enabled. For
example, you can type show file and press the Tab key. The command is completed, and show
filesystem is displayed.
Running exdsmgr commands at the command line
You can run many of the exdsmgr commands at the command line, as shown in the following
example. Commands that are suitable for running at the command line include the show commands.
This method of entering the commands allows you to pipe the output to less or more so that the
output does not scroll off the screen. This is useful where the output of the command is expected to
be lengthy; for example, when running the show server <server_number> and the show lun
<lun_number> commands:
# exdsmgr show server |less
Backend commands
Some exdsmgr commands are executed by a backend command processor. These include the boot
server, shutdown server, and install server commands. The exdsmgr command dispatches
the command to a background process that is responsible for running the actual command. The
exdsmgr command shows output from these commands but does not actually execute the commands.
You can tell when this is happening because exdsmgr prints a command ID as shown in the following
example:
[root@glory1 ~]# exdsmgr boot server 2–4 Command id 2724
Sending the command to the background
Press Ctrl-C to return to the ExDS> prompt while the command continues to run in the background.
