Administrator Guide

Before modifying the group name or group IP address, make sure you understand how these changes will aect your environment:
• You identify replication partners by group name and use the group IP address to perform replication. If you modify the group
name or IP address, make sure replication partner administrators make the change to their partner conguration. Replication fails
if the partner information is incorrect.
• You use the group IP address as the iSCSI discovery address when connecting initiators to iSCSI targets in the group. If you
modify the group IP address, you might need to change your initiator conguration to use the new discovery address.
• You use the group IP address to access the group for management purposes, unless you congured a dedicated management
network. If you modify the group IP address, make sure administrators are aware of the change.
• Changing the group IP address disconnects any iSCSI connections to the group and any administrators logged in to the group
through the group IP address.
• If you change the IP address of a group for which you are running the GUI locally, or congure a management network for the
group, you must uninstall the standalone GUI application and then install it again.
• Applications such as SAN Headquarters use the group IP address to access the group for monitoring purposes. If you modify the
group IP address, you must modify the SAN Headquarters conguration to use the new group IP address.
• If you modify the group network conguration (for example, if you modify the group IP address), you might need to make a
reciprocal adjustment to the NAS cluster SAN network conguration.

Add a Member to an Existing Group
To add a member to an existing group, you can use either the Remote Setup Wizard for Windows or Linux, or the CLI setup
command to run the Group Manager setup utility.
The setup utility congures an array as either the rst member of a new group or as an additional member of an existing group.
During the conguration, the utility prompts you for information such as the name of the member, the name and IP address of the
group, and a password for managing group membership. The utility also provides information about what to do after the member has
been added. See the Dell EqualLogic Group Manager CLI Reference Guide for more information.
When you add a member to a group, keep the following considerations in mind:
• You need the group membership password that is initially established when you create the group. (Note that the group
membership password is not the same as the grpadmin password.)
• The new member and the existing group must use compatible rmware levels. Typically, being compatible means having the
same major rmware version, but not always. You might need to initially deploy the new member as its own group to have its
rmware version be compatible with the existing group.
• The new member must use the same protocol as the group. If the member is joining an IPv6 group, specify the ipv6 option with
the command.
• If you attempt to add a member that does not support IPsec to an existing group in which IPsec is used, setup will not be able to
add the member to the group.
• If you are adding a member to a group that uses data center bridging (DCB), you must specify the DCB VLAN ID for the new or
existing group.
After you add the member, perform the same post-setup tasks as when you initially congured the group. For example:
• Enable the other network ports (see the Installation and Setup Guide for your array)
