then configure the creator server to run verification on the remote computer, setting the verification server’s Global Verification
window to 24 hours.
You can run remote verification operations manually, you can schedule them individually, or you can schedule them as part of a
Global Verification task.
Remote Host Checksum Verification and Soft Recovery in a HIT Group
If you want to run Checksum Verification and Soft Recovery on a remote host and your configuration consists of a HIT Group
with two or more hosts, Dell recommends the following:
● If your HIT Group is a DAG, then each node has a unique backup document directory. As a result, each node requires a
remote host for Checksum Verification and Soft Recovery.
● The cluster node and its remote host share the same backup document directory. For example, if your HIT Group comprises
a 4-node DAG, then you must allocate four separate hosts for remote host Checksum Verification and Soft Recovery (1 host
per node).
NOTE: This allocation is used only once when verification is set to complete simultaneously on all four hosts.
Prerequisites for Configuring a Verification Server
● Install the same release of Host Integration Tools on both the verification server and on the Smart Copy creator servers.
● Install the Exchange management tools for the same release of Exchange Server as is installed on the Smart Copy creator
servers.
● Maintain version parity on creator and verification servers, including the latest available Microsoft hotfixes.
● Ensure that:
○ The verification server and any servers that created the Smart Copies are part of the same Windows domain.
○ The verification server and any servers that created the Smart Copies are able to access a shared location for Smart
Copies.
○ Network access and bandwidth are available to process the Global Verification tasks of client computers.
○ A UNC or shared location exists.
Configure a Verification Server
You must ensure that the Exchange utility that performs the Checksum Verification and Soft Recovery tasks is installed on
whatever host you are configuring as a verification server. If you installed Exchange on the server, then this installation is taken
care of for you. However, a full Exchange installation is not needed for a host to be a verification server.
NOTE:
Dell recommends that the verification server not be an Exchange Server so as to not affect mail services. If the
servers are the same, you must manually copy the eseutil.exe and ese.dll files to the verification server.
1. Start the Remote Setup Wizard to enable the verification server to access the PS Series group.
2. Find the location of the shared Smart Copy folder on the creator server.
3. Launch ASM/ME and click Settings in the navigation area.
a. Click General Settings.
b. Find the path specified for the Auto-Snapshot Manager Document Directory.
In a DAG path, this is the UNC path.
c. Copy the path to a text file or write it down.
4. Configure the volume access control records on the PS Series group as follows:
● For snapshot Smart Copies, the host must have access to the volume and its snapshots.
● For clone Smart Copies, the host must have access to the volume.
● For replica Smart Copies, the host must have access to the replication partner, where the replica sets are stored. Also
make sure that the original volume (on the primary group) is not accessible by the verifier host.
For more detailed information, see the Creating Access Control Records procedure in the Group Manager GUI online help.
