The first thing administrators notice when they setup their EqualLogic box for the first time is the high level of automation that is built in. The box literally initializes itself and quickly recommends that “I’m ready, now go use the GUI to set up your volumes”. Taking the machine’s recommendation, most administrators fire up a browser, enter the GroupIP and presto – start creating volumes using the Group Manager.

EqualLogic GUI

Over time, however, administrators will dig deeper into the features of the box and will inevitably begin asking “how can I do X in my environment”?  Knowing that most GUIs are merely a front-end for calling system commands, administrators quickly discover the Command Line Interface (CLI).

2 Ways to Access the CLI

There are 2 ways to access the CLI: Network or Serial Connection

  • Network connection. Use telnet or SSH to connect to the group IP address. 

  • Serial connection. If you do not have network access to the group, use the serial cable (or cables) shipped with the array. See the Hardware Maintenance manual shipped with your array for more information.

Note: When managing an individual array, you must use a serial connection to the array or use telnet or SSH to connect to an IP address assigned to a network interface on the specific array. Do not connect to the group IP address.

Commands on page 3-2 for details. Once connected to the group (or an array), press the <Enter> key and log in to a group administration account (for example, grpadmin). You can then enter CLI commands at the command prompt.

The following example shows how to use telnet to log in to a group.

That’s it. You are now connected and can issue any number of administrative commands. In future posts we will look at command categories as well as how to use host based scripting to control the EqualLogic group and members.
