NOTE: SAS HBAs have two ports. The World Wide Port Name (WWPN) for port 0 ends in zero and the WWPN for
port 1 ends in one.
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.
2. Access the Host Setup wizard by doing one of the following:
• From the Welcome screen, click Host Setup.
• From the Home topic, click Action > Host Setup.
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
volumes. Click
Next.
NOTE:
Dell EMC recommends that you update the volume name with the hostname to better identify the volumes.
8. On the Summary page, review the changes, then click Configure Host.
• Click Yes to return to the Select Host page of the wizard, or choose No to close the wizard.
• Click Previous to go back and change the settings.
Enable multipathing on SAS volumes
Perform the following steps to enable multipathing on SAS volumes:
1. Log in to the VMware vCenter Server, then click the ESXi host.
2. On the Configure tab, select Storage > Storage Adapters.
3. Select the SAS HBA and click Rescan Storage.
The Rescan Storage dialog box opens.
4. Click OK.
5. Select the Dell EMC disk that was added to the ESXi host in Register the host and create and map volumes.
6. Click the Properties tab that is located below the selected disk.
7. Click Edit Multipathing.
The Edit Multpathing Policies dialog box opens.
8. Select a multipathing policy for the volume from the Path selection policy drop-down list and click OK.
NOTE:
The VMware multipathing policy defaults to Most Recently Used (VMware). Use the default policy for a host
with one SAS HBA that has a single path to both controllers. If the host has two SAS HBAs (for example, the host
has two paths to each controller), Dell EMC recommends that you change the multipathing policy to Round Robin
(VMware).
9. Repeat steps 5–8 for each SAS volume that is attached to the ESXi host.
VMware volume rescan and datastore creation
Perform the following steps to rescan volumes and create datastores:
