• If you are running SAN Headquarters, you must update the group IP address in the application to the dedicated management
address. For more information, see the SAN Headquarters documentation.
• If you are using an NTP server, Dell recommends that the NTP server be on the same subnet as the dedicated management
network.
Display Management Network Information
1. Click Group → Group Conguration.
2. Click the Advanced tab.
3. Click Congure management network to display details.
The management network address is shown in the Management IP address eld. (This eld is not shown if the system does not
have a management network.)
The General Settings panel also shows the group IP address, which you use for all iSCSI trac, including trac between replication
partners.
Uncongure a Management Network
You can uncongure a dedicated management network and reenable the group IP address to be used for group management.
This operation is in two parts. First, you disable and stop using the current management network address, and then you change the
management network interfaces on all the group members so that they again support all trac.
Disable and Stop Using the Management Network Address
1. Click Group → Group Conguration.
2. Click the Advanced tab.
3. Click Congure management network.
4. Clear Enable dedicated management network in the Congure Dedicated Management Network dialog box.
5. Click OK. The Group Manager GUI automatically restarts, using the group IP address.
6. Log in to the group.
Recongure the Member Management Network Interfaces
For each member in the group, prepare the physical connections:
1. Click Group.
2. Expand Members and then select the member name.
3. Click the Network tab.
4. Select the former management interface and then click Modify IP settings.
5. If you do not want to use the interface, delete the IP address and click OK in the Modify IP Settings dialog box.
If you want to use the interface:
a. Change the IP address and subnet mask to the iSCSI network.
b. Clear Restrict to management access.
NOTE: On some arrays, you cannot select Restrict to management access. In such cases, this option is not
bold.
c. Select Enable this interface, then click OK.
To log in to and manage the group, connect to the group IP address.
Secure Erase
You can securely erase data so that it cannot be recovered. Secure erase zeroes the data on the disk when a volume is deleted or
moved o of the array. However, compressed data residing on the disk is not zeroed out on deletion. This feature supports member
vacate and page move operations.
When a secured volume is deleted, the following occurs:
