Virtual Connect FC Modules - Blades NOT-LOGGED-IN

[Lee M]

I have 4 enclosures all with identical configurations and f/w levels. Connected to same Cisco Fabric switches. 3 are working fine the other has the VC FC uplinks logged in but all of the Blades show as NOT-LOGGED-IN ? I have logged a call with HP but thought someone may have had a similar problem.

[JKytsi]

Trivials first ...
You have FC HBA in blades ?
Is it in correct mezz slot ?

Go to FC HBA BIOS and scan for targets, see if there is any difference.

[Lee M]

Yep,

see attachment, this enclosure is configured exactly the same as the other 3, all have HBA Mezz in correct port.

I have hit ctrl-q and scanned fibre still not-logged-in?

[The Brit]

Lee,
Although you dont specify, I have to assume that your enclosure is a c7000.

And this might seem like a repeat request, can you confirm that you blade HBA's are on Mezz1! (you didnt actually confirm that)

Also can you confirm that you have NPIV enabled on the SAN Switch Ports.

Dave.

[Lee M]

Yes, they are in correct Mezz port 1 (the other 3 enclosures are all working ok) it is a c7000, NPIV is enabled on the switches and the other 3 enclosures are connected to the same switches.

I have power cycled fc modules, created a new server profile, changed from dynamic to static port mappping, changed from auto to set speed all with no joy? I don't think this is a simple mis-config as all 4 enclosures are config'd exactly the same with same f/w etc.

I have asked for NPIV to be disabled / re-enabled but as the other 3 enclosures are working ok, they are unwilling to do this at the moment.

I'm at a loss as to what step to take next? Don't really want to delete VC domain and start again as all zoning etc. would need re-doing plus we have people working on blades in the enclosure now too?

[Steven Clementi]

Will "they" disable / enable the ports those VCM's are plugged into?

I find it funny since... every time "they" say it is working properly on "their" end... it usually isn't. (at least that's been my experience).


Are all the port settings the same on the SAN Switch side? Can you get a print out to confirm?

[Lee M]

Hi,
got the ports disabled / enabled and checked with them and all settings appear to be the same as on the working ports?

[Johan Guldmyr]

Hi, are these servers booted?
I know that when you are using boot from SAN the servers are not "logged in" until the server has actually booted from SAN.

[Lee M]

Some of the servers are built and booted into O/S, i have been testing with one in Qlogic BIOS and rescanning fibre. no joy!

[kris rombauts]

Lee,

just a wild guess since the rest seems to be all OK.... the WWN's used by the server blades in this enclosure don't happen to exist already on the SAN (i.e. when using VC assigned WWN ranges).



just a thought

Guys,
thanks for all your replies, i decided to power cycle all of the vc modules , ethernet and fibre (after I informed all users that network would be down for a few mins), this has kicked things into life and the blades are now logging into the fabric. Phew !

[Johan Guldmyr]

Sweeet!

[JKytsi]

What FW You are running in VC modules ? Sounds like old.

[Lee M]

All updated to 2.32 about 6 weeks ago (before 2.33 came out).

[David McGaughey]

I'm having this same problem on a new C7000 with latest flashes on the VC, HBAs, and interconnect cards. NPIV is enabled on connecting switch ports. Did just rebooting the fiber VC cards really fix this issue?

All my servers are running HP's version of esxi 4.0 with all updates applied. You can see the port there in the VCEM assigned to the server, but it won't log in and when there's no balancing of I/O going on to the SANs because of it.

[Lee M]

not just the fc modules but the entire vc domain was power cycled ethernet modules too (as they run vcm), good luck!

[David McGaughey]

Booting the whole VC set of cards does force the ports back to "LOGGED-IN". I'm hoping that they stay that way. I've also got a ticket open with HP on the issue.

[Thomas Kaufmann]

Hi,

i´ve the same problem here. On your hint, i´ve resetted all of the VC switches (2xFlex-10, 2x 4GB VC-FC).
But the problem still persists.
How do you made the resets. Directly on the hardware or via Blade OBA?
I´ve done it via OBA--> Interconnect Bays--> virtual buttons-->reset

[David McGaughey]

I popped the cards out and replaced them. But this only fixed the problem for a short time. I've now flashed everything again. It was installed first of this August and flashed by HP, but already there are new firmware flashes for the Emulex HBAs. I'm currently testing those flashes.

[Thomas Kaufmann]

Hi guys,

Restarting of the VC Modules doesn´t solve the problem in my case.
After a while browsing the HP Knowledgebase i found
https://www13.itrc.hp.com/service/cki/docDisplay.do?docId=emr_na-c01965820&docLocale=en&admit=109447627+1283868799207+28353475

As i had the 1.30 on the VC-FC Modules i did the update to 1.40 and.... strike!
This solved the problem.

Same problem here, but with a couple of perhaps minor differences.

C3000
Firmware:
OA 3.11
VC 3.01/1.40
Server firmware set 9.10C

Have not physically removed interconnects, only powered down from OA.

Status is still "NOT-LOGGED-IN"

Any more ideas?

[David McGaughey]

I've now had a ticket open with HP on this issue for 30 days and haven't had a solution - though we've tried a lot of things.

I now have a working config, but I don't like it: I set all the ports on the VC to 4Gb and the ports they plug into on the switches to 4Gb. The blades immediately logged in and I've been pounding the heck out of them with no errors or problems. Fail-over works perfectly.

Appears to me the the new 8Gb VC's will only run at half their rated speed. I'm using HP resold Brocade switches. I've tried different, new out of the package HP patch cables - no help.

[Cajun Computer Geek]

I'm using 4GB VC-FC modules.

Where did you set the link speed in VCM? In the server profile? I hard coded the link speed on the server profile and the 2 ports on the Brocade 4GB switch to 4GB and still get "NOT-LOGGED-IN".

[Lee M]

You need to power off the ethernet modules as well as the fc modules, all 4 at the same time. Then power on the ethernet first. Hopefully will fix the NOT-LOGGED-IN issue.

[Cajun Computer Geek]

That's exactly what I did. There are 3 modules in this C3000 enclosure, 1-10 VC-Enet in bay 1, 4GB VC-FC in bay 3, and a Brocade 4GB module in bay 4.
