Global VSANs
You can define global VSANs in the domain group root, or a domain group below the root. Global VSANs are fabric-interconnect specific and can be created for either Fabric A or Fabric B. A global VSAN cannot be a common VSAN.
Resolution of global VSANs takes place prior to the deployment of global service profiles. If a global service profile references a global VSAN, and that VSAN does not exist, deployment of the global service profile fails due to insufficient resources. All global VSANs created in a Cisco UCS Central account must be resolved before deploying the global service profile.
A global VSAN is not deleted when you delete a global service profile that references it. Delete the global VSAN from the Cisco UCS Central account.
A global VSAN is visible to a Cisco UCS Manager account only if you deploy a global service profile that references the VSANs. Once a VSAN that is deployed with a global service profile becomes available in a Cisco UCS Manager account, you can include it in a local service profile and policy. You cannot turn a global VSAN into a local VSAN.
Creating a Global VSAN
You can create a global VSAN with IDs from 1 to 4093, except for those in the following reserved ranges:
-
If you plan to use FC switch mode in a Cisco UCS domain, do not configure VSANs with an ID in the range from 3040 to 4078.
-
If you plan to use FC end-host mode in a Cisco UCS domain, do not configure VSANs with an ID in the range from 3840 to 4079.
Note |
FCoE VLANs in the SAN cloud and VLANs in the LAN cloud must have different IDs. Using the same ID for an FCoE VLAN in a VSAN and for a VLAN results in a critical fault and traffic disruption for all vNICs and uplink ports using that VLAN. Ethernet traffic is dropped on any VLAN which has an ID that overlaps with an FCoE VLAN ID. |
