How to tell which HBA's are connected via the EFI

We have a RX8640 that was moved from one rack to another to be re-purposed.

It has 16 HBA ports.

Only 4 cables were plugged in.

We only have EFI access.

Is there a way to tell which HBA ports by WWN that are connected?

 

Example:

 

drvcfg -s <slot number> <connect_n)> provide a menu... in this menu there is an option for info
this info only giving me WWN / WWPN
but there is no information about connection

Enter a Selection: 8

 Adapter Path:  Acpi(PNP0002,02)/Pci(01|00)/Pci(04|00)

 Adapter WWPN:   500143800110AE44

 Adapter WWNN:   500143800110AE45

Do you want to select the correct boot device?

Best practice: save an "ioscan -fne" including the EFI path.

So you can compare the "EFI> map" output.

Hope this helps!

No, we want to provide the storage team with the WWN's so they can assign luns to the server.

There is no OS currently installed.

IIRC we used to boot into recovery shell and run fcmsutil to get this information.


Hope this helps!
