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.
● Virtual disks are created and they are assigned as Virtual Adapter 1, Virtual Adapter 2, Virtual Adapter 3, or Virtual
Adapter 4. For more information, see Applying Virtual Adapter Access Policy to Virtual Disks.
NOTE:
● You can map only one virtual adapter to one server at a time.
● Without an appropriate license, you can unmap a VA–server assignment, or map the VA to the default serve, only.
● The default mapping is VA1–Server Slot 1, VA2–Server Slot 2, VA3–Server Slot 3, and VA4–Server Slot 4.
● If full height server is inserted then the upper slot has the VA mapped to it while the bottom slot is still unmapped. For
example a full height in slot 1 has VA1 assigned to slot 1 and VA3 is still unmapped.
● If the system has an enterprise license then the you can assign any one of the four VAs to a server slot. However, you
can still map one virtual adapter to one server at a time.
● Virtual adapter rules are applied to the external and integrated shared storage adapters.
To map or unmap a virtual adapter from a server slot:
1. In the left pane, click Chassis Overview > Storage > Setup > Virtualization.
The Storage Virtualization page is displayed.
2. To select the required type of assignment, from the Assignment Mode: Virtual Disks to Virtual Adapters table, select:
● Single Assignment — Select to assign one virtual disk to one virtual adapter.
● Multiple Assignment — Select to assign a virtual disk to multiple virtual adapters. Read the on-screen instructions
before selecting this option.
NOTE:
Select the Multiple Assignment mode only when the servers have Cluster Services installed on them. Use of
this mode without Cluster Services may lead to corrupted or lost data.
3. In the Virtual Adapters Mapped table, from the Action drop-down menu, select one of the following options, and then
click Apply.
● <Slot #> — Select the slot to which the VA must be assigned.
● Unmap — Select to remove the VA assignment to a slot.
The VA is mapped or unmapped from the selected server slot, based on the selected action..
NOTE:
Consider a VA assigned to server in the lower slot ( 3 or 4) . When a half height server (slot 3 or 4) is replaced
with a full height server, the full height server does not access the VA assigned to lower slots. Inserting a half height
server again, provides access to the VA.
