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:

    In this field…​ Do this…​

    Storage System

    Select the SVM for the LUN you will map to the igroup.

    Host

    Select the host on which you want to create the igroup.

    Igroup Name

    Enter the name of the igroup.

    Initiators

    Select the initiator.

    Type

    Select the initiator type, iSCSI, FCP, or mixed (FCP and iSCSI).

  5. When you are satisfied with your entries, click OK.

    SnapCenter creates the igroup on the storage system.

Rename an igroup

You can use SnapCenter to rename an existing igroup.

Steps

  1. In the left navigation pane, click Hosts.

  2. In the Hosts page, click Igroup.

  3. In the Initiator Groups page, click in the Storage Virtual Machine field to display a list of available SVMs, and then select the SVM for the igroup you want to rename.

  4. In the list of igroups for the SVM, select the igroup you want to rename and click Rename.

  5. In the Rename igroup dialog box, enter the new name for the igroup and click Rename.

Modify an igroup

You can use SnapCenter to add igroup initiators to an existing igroup. While creating an igroup you can add only one host. If you want to create an igroup for a cluster, you can modify the igroup to add other nodes to that igroup.

Steps

  1. In the left navigation pane, click Hosts.

  2. In the Hosts page, click Igroup.

  3. In the Initiator Groups page, click in the Storage Virtual Machine field to display a drop-down list of available SVMs, then select the SVM for the igroup you want to modify.

  4. In the list of igroups, select an igroup and click Add Initiator to igroup.

  5. Select a host.

  6. Select the initiators and click OK.

Delete an igroup

You can use SnapCenter to delete an igroup when you no longer need it.

Steps

  1. In the left navigation pane, click Hosts.

  2. In the Hosts page, click Igroup.

  3. In the Initiator Groups page, click in the Storage Virtual Machine field to display a drop-down list of available SVMs, then select the SVM for the igroup you want to delete.

  4. In the list of igroups for the SVM, select the igroup you want to delete and click Delete.

  5. In the Delete igroup dialog box, click OK.

    SnapCenter deletes the igroup.
