How do I find the WWN of AUX0 and AUX1

Jump to solution

I want to configure some FC zones for my VNX Datamovers to see my Tape Library.

The two interfaces AUX0 and AUX1 are not showing link LEDs.  I've tried setting the speed to 8Gb and Autonegotiation and rebooting the Datamover.

I haven't been able to find out either how to show the WWN of the ports?

Many thanks.

Should AUX0 and AUX1 automatically log into the FC switches when connected?

I don't have link LEDs.

yes they should, the other day i could not get it to login so had to "shut" and "no shut" the port on FC switch.

I've tried bouncing the ports on the switch but no change.

Not sure what else to do as EMC support don't want to help. They want to "engage professional services".

cables look good ? (transmit/receive are not reversed ?) . Let's try resetting the port on the datamover itself.

.server_config server_2 -v "fcp portreset=2"

notice the "dot" in front of server_config, this will reset this port (in bold), after that try "shut" "no shut" again.

It does appear to be a cable problem.

I ran a cable directly from server_3 AUX1 port to the switch, bypassing the patch panel and it came up immediately.

Am I correct in thinking server_2 is at the right hand side when looking from the back of the unit?

Ok problem sorted. Swapped the channels round on the cables.

The structured cabling must be reversed on my last four ports

Thanks for your help. I have the commands now for troubleshooting.

yes, server_2 is on the right hand side. I don't know what cables you use but on some you can take the housing off and swap rx/tx

Again, many thanks for your help.

Only after re-reading the whitepapers did the penny finally drop "direct attach tape library".

So yes as you mentioned, I swapped the rx/tx channels on the cables and the ports enabled immediately.

I was able to perform a backup of one of my CIFS shares, 189GB @ 7.9GB/min. Not too shoddy.

Would you indulge me one more question, in my backup software I can see the NAS share on the VNX. I cannot see any folders underneath though. I can backup fine and it shows me the individual files and folders within the restore window.

Would this be a common issue perhaps with VNX config or do you think this is entirely down to my backup software? (CA ARCserve)
