Step 1: Select host for a volume

In the first step, you can select a specific host or host cluster for the volume, or you can choose to assign the host later.

Make sure that:
  • Valid hosts or host clusters have been defined (go to Provisioning > Configure Hosts).
  • Host port identifiers have been defined for the host.
  • The host connection must support Data Assurance (DA) if you plan to create DA-enabled volumes. If any of the host connections on the controllers in your storage array do not support DA, the associated hosts cannot access data on DA-enabled volumes.

Keep these guidelines in mind when you assign volumes:

  • A host's operating system can have specific limits on how many volumes the host can access. Keep this limitation in mind when you create volumes for use by a particular host.
  • You can define one assignment for each volume in the storage array.
  • Assigned volumes are shared between controllers in the storage array.
  • The same logical unit number (LUN) cannot be used twice by a host or a host cluster to access a volume. You must use a unique LUN.
  • If you want to speed the process for creating volumes, you can skip the host assignment step so that newly created volumes are initialized offline.
Note
Assigning a volume to a host will fail if you try to assign a volume to a host cluster that conflicts with an established assignment for a host in the host clusters.
  1. From the Manage page, select the storage array.
  2. Select Provisioning > Manage Volumes.
  3. Select Create > Volumes.
    The Select Host dialog box appears.
  4. From the drop-down list, select a specific host or host cluster to which you want to assign volumes, or choose to assign the host or host cluster at a later time.
  5. To continue the volume creation sequence for the selected host or host cluster, click Next, and go to Step 2: Select a workload for a volume.
    The Select Workload dialog box appears.
