Re: /dev/fcms2 when connected to fabric shows driver state dead

Hi,

What model server is this & what is the model number of the FC card?

If this is a D/R/K class & the card is a 3404 well then the problem would be that the card is not switched fabric capable - only link-loop.
That would match your symptoms 100%.

For those systems you'd need the A6685A card which is an HSC bus FC card that is switched fabric capable.

HTH,
Jeff

Thanks JEff, the machine is R class(9000/800/R390), the fc card - not sure about the model, pl let me know how can I check the fc card model( without opening the machine).

Re: /dev/fcms2 when connected to fabric shows driver state dead

I don't know if this works for your card, but try

fcmsutil /dev/ vpd

or run the STM info tool on it.

Hope this helps!
Regards
Torsten.

Re: /dev/fcms2 when connected to fabric shows driver state dead

Well, I don't know for sure (we don't have any more of them) if the model number is printed on the outward facing bracket of the 3404 card - but it *is* on the 6685. So check card from the outside of the server.

Re: /dev/fcms2 when connected to fabric shows driver state dead

Out of curiosity I poked around the datacenters & found an old K that's on it's way to decommissionville & it had A3404As in it & they are indeed labeled on the outer bracket as such. So just poke your head into the back of the rack & you'll have your answer.

Re: /dev/fcms2 when connected to fabric shows driver state dead

Jeff may be on the right track here. I had issues with a fibre card in a V-class that did not support the fibre setup I needed it to.
If at first you don't succeed, read the man page.

Hi Jeff,

The card model no is A3591B.

Pl let me know this supports fabric or will work only with "IN_LOOP"

Re: /dev/fcms2 when connected to fabric shows driver state dead

Use fcmsutil test

fcmsutil device_file test remote-N-Port-ID

To get n port id

fcmsutil /dev/td? devstat all | more

to get a /dev/td use ioscan

ioscan -funC fc

Here's the link to fcmsutil

Re: /dev/fcms2 when connected to fabric shows driver state dead

I checked partsurfer & although I can't definitively tell you that 3591 is *not* switched fabric capable I can tell you that when it resolves down to the "actual" device it comes out as 3395. Now with that part # being lower than 3404 I would bet $ to donuts that it is not switched fabric capable.
So I think a 6685 card is what you really need - period.
I'll also tell you that *every* EMC, Hitachi or HP XP quote I've ever seen has stated that the *only* HSC FC card they support is the 6685 so you better get a quote on 'em if you're really going switched fabric.

My $0.02,
Jeff
