To add a member to a group, you need the group membership password that is initially established when you create
the group.

Shutting down a group
Before shutting down a group, see Impact of modifying the group network configuration on page 5-5.
To perform maintenance, you might need to shut down a PS Series g
roup. While the group is shut down, group
volumes are not available.
1. Stop applications using the group volumes.
2. Disconnect iSCSI initiators from the group volumes.
3.
Shut down each group member. See Shutting down a member on
page 6-14.
Note: Do not turn of
f power to a group member until you cleanly shut down the member.
To start the group, power on all group members.
Enabling or disabling performance load balancing (advanced)
Note: Dell recommends that you enable performance load balancing. Disabling load balancing degrades SAN
performance.
By default, the group tries to store volume data on pool members with a RAID configurat
ion optimal for volume
performance, based on metrics collected from each group member. You can enable or disable automatic
performance load balancing. Other load balancing methods continue to apply.
1. Click
Group, then Group Configuration, and then the Advanced tab.
2. In the Load Balancing panel, select or deselect
Enable performance load balancing in pools
(Alt+E).
3. Click Save all changes (Control+S).
