How to setup this DELL SAN storage to be joined to the existing group?

I was given a task to setup and then configure to join this DELL EqualLogic PS6100E to existing group for storage disk space. This is a 4u 24 hard disk slot enclosure, with dual controller. Now, with serial port connect, and I was presented with the setup procedure as shown in attached doc. The dilemma is, shall I continue with setup to key in the following:
    - member name
    - network interface and IP
    - default gateway
    - Existing Group Name and IP
    - or create a new group

I wasn't given any information about the existing Group name/ip, admin/password; and also, the existing group is located at different site.  Should I continue the setup and then join to the existing group when this SAN is moved to the destination site?
Or any best practice?

Thanks in advance.

All members of a group needs to be on the same network and subnet. What is the purpose of this array, and how does it relate to the other array?

Upon further reading, it looks like it will be moved to the other site. You can't do the setup until you get it onto the same network as the other site. You will need the existing group name and the password to join the group, as well as the IP addresses that you will be using for your interfaces.

Hi Kevinhsieh,

Okay. Any other thing to look for for joining to the existing group. A last question is does joining the existing group need any downtime?
No downtime to add a group member. Firmware between the arrays ideally should be the same. I would talk with Dell support before doing this. There are so many ways to do something stupid when dealing with storage that I cant think of them all. EqualLogic isn't particularly hard, but it isn't idiot proof either.
