Scenario: I needed to add another Equallogic to our existing group but couldn’t remember the group membership password (or to be more accurate , the password I had stored didn’t work!)
This is extremely easy and has no affect on the running/settings of the current group.
Firstly telnet or SSH to your device (make sure it is the group manager IP address)
# telnet 192.168.1.1
Then issue the following commands
# <enter new password>
Now you can add your (hopefully) new and shiny Equallogic to your existing group.
