Register the host and create and map volumes
Perform the following steps to register a host, create volumes, and map volumes:
1. Log in to the ME Storage Manager.

3. Confirm that you have met the listed prerequisites, then click Next .
4. Enter a hostname.
5. Select the SAS initiators for the host you are configuring, then click
Next .
Use the information from step 5 of the Attach SAS hosts to the storage system procedure to identify the correct SAS initiators.
6. Group hosts together with other hosts.
a) For cluster configurations, use the “Host groups” setting to group hosts in a cluster.
• If this host is the first host in the cluster, select Create a new host group , then provide a name and click Next .
• If this host is being added to a host group that exists, select Add to existing host group . Select the group from the drop-
down list, then click Next .
b) For stand-alone hosts, select the Do not group this host option, then click Next .
7. On the Attach volumes page, use the options to change the volume name and size, select the pool for the volume, and add or delete
