Assigning Virtual Adapters To Slots Using CMC Web
Interface
Using the Virtual Adapter feature, you can share the installed storage with the four servers. You can map a
virtual disk to a server slot by first mapping a virtual disk to a virtual adapter (VA), and then mapping a
Virtual Adapter (VA) to a server slot.
• Before assigning a VA to a server slot, make sure that:
– The server slot is empty or the server in the slot is turned off.
– The VA is unmapped from a server or a slot.
– All affected servers are powered off.
