Options

--array-name | -a <array>

Uses <array>.

--array-file | -A <filename>

Reads array information from<filename>. The default looks first for $HOME/.array.xml, then for /etc/ifs/array.xml.

--directory | -d <directory>

Runs commands from the specified directory on remote computers. The current working directory is the default directory. An empty <directory> results in commands being run in the user's home directory on the remote computer.

--diskless | -D

Runs commands from diskless nodes.

--ignore-errors | -I

Suppresses the printing of error messages for nodes that return non-zero exit status. Returns the maximum exit status from all nodes.

--user | -u | -l <user>

Logs in as <user> instead of as the default root user.

--nodes | -n <nodes>

Runs commands on the specified nodes, which can be specified multiple times. Must be a list of either node names or ranges of logical node numbers (LNNs); for example, 1,3-5,neal8,10. If no nodes are explicitly listed, the whole array is used.

--pre-command | -P <command>

Runs the specified command before any other commands. This is useful for setting up the environment and it can be specified multiple times. You can specify - to reset the list of pre-commands.

--quiet | -Q

Suppresses printing of the host prefix for each output line.

--rpc-timeout<seconds>

The maximum period in secionds before the RPC channel times out. To disable, use the value 0.

--serial | -s

Runs commands in serial instead of parallel.

--storage | -S

Run commands from storage nodes.

--throttle | -T <count>

Adjusts throttling. To disable throttling, specify 0. The default value is 80 for multitasking and 35 for forking.

--exclude-nodes | -x <nodes>

Excludes specified nodes from the command. This argument is specified in the same manner as the -n option.

--exclude-down-nodes | -X

Excludes offline nodes from the command. This command is limited to cluster local use only.

Example

In SmartLock compliance mode, to run isi_for_array for a command that requires root privileges, you must specify sudo twice. For example, the following command runs isi statistics client list on each node in a compliance cluster.

sudo isi_for_array -u compadmin sudo isi statistics client list
