Options

{--array-name | -a} <array>

{--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.

{--known-hosts-file | -k} <filename>

Uses <filename> for SSH known hosts file instead of the default /dev/null directory.

{--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 node IDs; for example, 1,3-5,neal8,10. If no nodes are explicitly listed, the whole array is used.

{--password | -p | --pw} <password>

Uses the specified password instead of the default password.

{--pre-command | -P} <command>

{--quiet | -Q}

Suppresses printing of the host prefix for each output line.

{--serial | -s}

Runs commands in serial instead of parallel.

{--storage | -S}

{--transport | -t} <transport-type>

Specifies the network transport type. The default value is rpc. Valid transports values are rpc or ssh.

{--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
