5 Deselect the Temporarily Disable NPIV for this virtual machine check box.
6 Select Generate new WWNs.
7 Specify the number of WWNNs and WWPNs.
A minimum of 2 WWPNs are needed to support failover with NPIV. Typically only 1 WWNN is created
for each virtual machine.
The host creates WWN assignments for the virtual machine.
What to do next
Register newly created WWNs in the fabric so that the virtual machine is able to log in to the switch, and
assign storage LUNs to the WWNs.
Modify WWN Assignments
You can modify WWN assignments for a virtual machine with an RDM.
Typically, you do not need to change existing WWN assignments on your virtual machine. In certain
circumstances, for example, when manually assigned WWNs are causing conicts on the SAN, you might
need to change or remove WWNs.
Prerequisites
Make sure to power o the virtual machine if you want to edit the existing WWNs.
Before you begin, ensure that your SAN administrator has provisioned the storage LUN ACL to allow the
virtual machine’s ESXi host to access it.
Procedure
1 Open the Virtual Machine Properties dialog box by clicking the Edit link for the selected
virtual machine.
2 Click the Options tab and select Fibre Channel NPIV.
The Virtual Machine Properties dialog box opens.
3 Edit the WWN assignments by selecting one of the following options:
Option Description
Temporarily disable NPIV for this
virtual machine
Disable the WWN assignments for the virtual machine.
Leave unchanged
The existing WWN assignments are retained. The read-only WWN
Assignments section of this dialog box displays the node and port values
of any existing WWN assignments.
Generate new WWNs
New WWNs are generated and assigned to the virtual machine,
overwriting any existing WWNs (those of the HBA itself are unaected).
Remove WWN assignment
The WWNs assigned to the virtual machine are removed and it uses the
HBA WWNs to access the storage LUN. This option is not available if you
are creating a new virtual machine.
4 Click OK to save your changes.
