You create initiator groups (igroups) to specify which hosts can access a given LUN on the storage system. You can use SnapCenter to create, rename, modify, or delete an igroup on a Windows host.

Create an igroup

You can use SnapCenter to create an igroup on a Windows host. The igroup will be available in the Create Disk or Connect Disk wizard when you map the igroup to a LUN.

Steps

  1. In the left navigation pane, click Hosts.

  2. In the Hosts page, click Igroup.

  3. In the Initiator Groups page, click New.

  4. In the Create Igroup dialog box, define the igroup:
