NPIV enabled on vm but not seen in the guest

[santosh42]

Hi,

I have a esxi 5.0 with a qlogic hba. i created a VM and installed rhel on it.

Then, i enabled the npiv on this vm and saw that it generated node WWN and port WWN.

However, when i logged in into the guest, i am not able to see the port names in

/sys/class/scsi_host/host{n}/device/fc_host:host{n}/port_name

Is there any additional configuration on the VM side to enable the WWNs inside the guest?

Thanks in advance.

Hi,

here's a really detailed description of all tasks required to use NPIV with VMware.
