Hello, 

 That is extremely old firmware by the way.  

 This is a copy of the CLI guide

http://people.stern.nyu.edu/nwhite/scrc/ps4000e/110-6028-EN-R1_CLI_REFERENCE_V5.0.pdf

 It's also online 

http://psonlinehelp.equallogic.com/v4.0/Content/GABook/CLI_preface.htm

 This is for Firmware v6.x but the CLI commands are pretty much the same. There are some new commands post 5.x firmware 

http://psonlinehelp.equallogic.com/en/V6.0/groupmanager.htm

But once you log in you can do  "?" for available commands. 

 GrpName>show 

 That will give you a quick overview of the configuration.

 GrpName>show member 

 That will display the current array members in that group. 

 When you want to look at a specific physical member you use 'member select' 

 GrpName>member select MEMBERNAME show 

  E.g.  Grpname>member select PS6210 show 

  To see the IP addresses of that member

Grpname>member select PS6210 show eths

 

 The "?" can be use to show you the current option.
