Service Group Migration

Verify the service group can migrate to different hosts in the cluster by performing the following tests.

  To perform the service group migration test

1. Migrate the service group to a host attached to the same array:
   1. In the Service Groups tab of the Cluster Explorer configuration tree, right-click the service group.
   2. Click Switch To and click a system attached to the same array (hostb).

   The service group comes online on hostb and local volumes remain in the P-VOL/PAIR state.

2. Migrate the service group to a host attached to a different array:
   1. In the Service Groups tab of the Cluster Explorer configuration tree, right-click the service group.
   2. Click Switch To, and click Remote switch.
   3. Select a system attached to another array (hostc) and click OK.

   The service group comes online on hostc and volumes there transition to the P-VOL/PAIR state, changing the original P-VOLs to S-VOLs.

3. Migrate the service group back to its original host:
   1. In the Service Groups tab of the Cluster Explorer configuration tree, right-click the service group.
   2. Click Switch To, and click Remote switch.
   3. Select the system on which the service group was originally online (hosta) from the menu.

   The group comes online on hosta. The devices return to the original state in step 1.
