Setting assignment mode
Virtual disks can be assigned from one server slot to another by mapping the virtual adapter. For the
example used in this guide, the assignment mode should be set to Multiple Assignment. By default,
virtual disks are set to Single Assignment.
1. Select Storage on the left pane.
2. Select Setup from the top menu.
3. After the page populates, scroll to the bottom of the page and select the Multiple Assignment
radio button.
4. Click Apply.
IMPORTANT!: Multiple assignments should only be used with Microsoft
Failover Clustering scenarios. Do not use this mode unless the servers
have Cluster Services installed on them. Use of this mode without Cluster
Services may lead to corrupted or lost data. Verify the disks are offline on
all servers before beginning the cluster installation procedure.
