NVSRAM settings
SRM test failover requires a change to the default NVSRAM settings on the MD storage array. During test
failover, snapshots are created on the recovery site's storage array which is then mapped to the default
host group and the ESX or ESXi host group.
Before completing the following tasks, the RAID controllers must be rebooted. Dell recommends you to
complete the following tasks during maintenance or in a preproduction environment.
To change the NVSRAM settings:
1. Start MD Storage Manager on your storage array.
2. From the Enterprise Management Window (EMW), click Tools → Execute Script.
Figure 4. MD Storage Manager Execute Script
3. In the Script Editor window, to review your current NVSRAM settings, run the following command:
show controller[0] NVSRAMByte[0x3b];
NOTE: To test and run your command, on the Script Editor page, click Tools → Verify and
Execute .
Your current NVSRAM setting for the specified RAID controller [0] is displayed.
