About group network configuration
The group network configuration, which appears in the Group Summary window, includes the group name and
group IP address, which you set when creating a group:
• Group name – Identifies the group on the network. For example, when you configure a replication partner, you
use the name to identify the group.
•
Group IP address – Network address for the group. Yo
u use the group IP address as the iSCSI discovery
address when connecting initiators to iSCSI targets in the group.
You also use the group IP address to access the group for management purpos
es, unless you configured a
dedicated management network.
Impact of modifying the group network configuration
Before modifying the group name or group IP address, make sure you understand the impact of the modification.
You might need to make adjustments to your SAN environment because of the modification.
Consider the following:
• You identify replication partners by group name and use the group IP addres
s to perform
replication. If you
modify the group name or IP address, make sure replication partner administrators make the change to their
partner configuration. Replication fails if the partner information is incorrect. See Replication partner
requirements for information.
• You use the group IP address as the iSCSI disc
overy address when connecting initiators to iSCSI targets in the
group. If you modify the group IP address, you might need to change your initiator configuration to use the
new discovery address.
• You use the group IP address to access the group for managemen
t
purposes, unless you configured 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 conn
ections to the group and any administrators logged
in to the group through the group IP address.
• If you change the IP address of a grou
p for which you are running the GUI locally, or configure 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 addres
s to access the group for monitoring purposes.
If you modify the group IP address, you must modify the SAN HeadQuarters configuration to use the new
group IP address.
Modifying the group IP address or group name
Before changing the group name or group IP address, see Impact of modifying the group network configuration on
page 5-5.
Requirement: Group n
ames must be unique in your network environment. A group name can consist of one to 54
letters, numbers, or hyphens. The first character must be a letter or number.
IPv6 Note: If you ar
e using IPv6 addresses exclusively in the group, you must use the CLI to change the group IP
address. See the CLI Reference manual for more information.
