what tape library are you emulating, did you also try another aux port ?

listed Online in "vtl initiator show" on DD. That does look odd that everything is listed as OFFLINE, so server_3 is you active datamover right now ?

Yup... that was one of the first things i did... :-\

did you try to shut/no shut the port on the switch itself ?

I have not tried another AUX port on the data mover.

I'm emulating a L180.  The VTL works perfectly on the other Data Mover & this worked fine in the past.

The only alteration is I moved the Fibre Channel connection to a different switch.  I'm just worried that there's some form of a reboot that might be required to have the Data Mover register itself with the new switch so it can talk to the switch happily.

I'm hoping there's a command that will simulate taking that port down & having it register without rebooting the Data Mover... similar to the the FCP reset command i've already ran but that didn't work....

how hard would it be for you to swap SFP/cable with server_2 (assuming that guy works) and trying in your aux0 , if nothing in aux1 on server_3 ?

Yeah... i'm putting that off & dreading that.... but you're right.

I'll try swapping the GBICs first then i'll try changing the ports completely.

Data Mover 3 is 1 of 2 active DMs, correct.

Here's the output of the initiator show:

So yes, everything looks perfect on the Data Domain side.  I agree that this is Odd... very odd.

darn, since support is not providing you with anything helpful, how about brute force and failover/failback ?

Yeah... that's where I'm at... its just a major outage to do either. (same 5-minute window, so i would bounce).

My other fear... what if the reboot doesn't fix it?

Thanks for the help guys!

If you have recent code than a failover / failback is a lot less than 5 minutes

Typical these days is 1 minute for medium sized systems – 30 seconds for small and at most 2min for large

Failover / failback is twice an interruption but its typically 20 seconds less than a warm reboot on medium/large configs

No problem – just send a PO ☺

Swapped the GBICs, no luck

Swapped the auxiliary ports, no luck

I feel like a daemon is not running or something got locked up on these puppies...

At that point you can tell support you have exhausted all of the possible scenarios, give me a new datamover
