The configuration of the Dell SRDF Adapter is performed through the Array Managers wizard in the VMware SRM plug-in. The wizard should be invoked only after the connection between the VMware SRM servers at the protected site and recovery site has been established.
SRM is accessed through the vSphere Client or directly via FQDN or IP. The image in Figure 27 demonstrates how to access SRM from the vCenter.
Before protection groups or recovery plans can be configured, an array manager must be configured for each instance of the SRDF SRA to provide connectivity information for device discovery. The Add Array Manager wizard for configuring the array managers is invoked by highlighting the Array Based Replication menu and then selecting Add Array Manager as seen in Figure 28.
The array manager wizard allows both managers to be entered together as a pair. The wizard has five steps. First, select the appropriate SRA in Figure 29.
Next, in steps 2 and 3, add the local and remote array managers in Figure 30. The configuration of the storage arrays connected to the protected site can be determined by entering the hostname or IP address of the local and remote servers providing the Dell Solutions Enabler API services. If the local VMware SRM host has direct access to Gatekeepers and there is no remote Solutions Enabler server configured, enter in the hostname of IP address of the Windows SRM server(s). For the SRM Appliance, the IPs will always be the remote Solutions Enabler servers.
Note: If the Solutions Enabler API service is configured to listen on a non-default TCP port, a non-default port number can be optionally specified by appending the port number after a colon following the hostname/IP address of the Solutions Enabler server. For instance if the Solutions Enabler server is configured to listen at a non-default port such as 2739 the entry would be similar to this: symapiserver1.emc.com:2739
Once the array manager has been configured on the first site, a reciprocal array manager must be configured on the remote site. In the second array manager, the Solutions Enabler servers should be reversed from the first (the local Solutions Enabler server address is now the remote address and vice versa).
After initial setup of the array managers the SRA queries for active RDF groups from the discovered arrays on the local Solutions Enabler server. The SRDF SRA log will report messages, such as the one below, if an RDF group is successfully discovered.
[DiscoverArraysCommand::Run] Found a remote VMAX [000192603603] connected through director [RF-8H], remote director [RF-8H] and RA group [30], remote RA group [30]
After both array managers have been configured the array pairs can be enabled within the wizard in Figure 31.
The wizard will automatically check the box for the appropriate pair arrays (one or more). Once a pair has been successfully enabled for one array manager that pair will be enabled on the other respective array manager.
It is important to note that these array pairs must be enabled in order to discover devices from them. Therefore, for 2-site replication environments the array pair including the source and target array must be enabled. For 3-site solutions only the array pair including the workload site and the chosen target site must be enabled. Any pair including the third “bunker” site does not need to be (and typically can’t be) enabled. Figure 32 shows the enabled pairs for one of the recently added array managers.
Finally, in step 5 in Figure 33, complete the wizard.

If no array pairs show up in step 4, this usually indicates a configuration problem. Refer to the SRDF SRA logs for detailed information, but typically it is one of the following reasons:
If one or more array pairs fail to enable, it means that the remote SRM server does not have an array manager that has discovered the same pairs. Ensure that the remote Solutions Enabler server has the proper access to the correct arrays.
Note that if there is more than one array configured as local on the protected or recovery site (or both), the user will be able to enable more than one array pair as shown in Figure 34
