Using the Group Manager Command Line Interface

The Group Manager CLI enables you to enter commands on a command line (or in a host-based script) to manage a group or a specific array.

To access the group to run CLI commands, you can do one of the following:

• Use a network connection. From a host, use telnet or SSH to connect to the group IP address or—if you are running array management commands on a specific array—connect to an IP address assigned to a network interface on the array.
• Use a serial connection. Set up a serial connection to the array, as appropriate for the control module model. Make the connection to serial port 0 on the active control module (the ACT LED will be green). Use the serial cable that shipped with the array. The serial connection must have the following characteristics:
• 9600 baud
• One STOP bit
• No parity
• 8 data bits
• No hardware flow control
• Once connected to the group, log in to a group administration account, such as grpadmin. You can then enter commands at the CLI prompt.

There are three types of CLI commands:

• Group management commands. These commands manage the group, members, and volumes. They use a tree structure and generally require subcommands, parameters, or variables.
• Array management commands. These commands perform tasks only on a specific array. To run, you must use a telnet or ssh connection to an IP address assigned to a network interface on the array, not to the group IP address. Alternately, you can use a serial connection to the array.
• Global commands. These commands provide access to common command options and can be executed anywhere in the CLI tree structure.

By default, telnet and SSH access to the group is enabled. For information about enabling and disabling access, see Controlling GUI and CLI Management Access.

For detailed information about using the CLI to manage a group and individual arrays, see the PS Series CLI Reference manual.
