Re: Having issues attaching to LUNs after Brocade mode change

Here is a Brocade procedure for changing interop mode: Solution Guide: Migrating from McData Fabric or Open Fabric Mode (IM2 or IM3) to Brocade Native Fabric Mode (IM0)

Having issues attaching to LUNs after Brocade mode change

We recently had a Brocade mode change and when the channel came back we were flooded with the following messages and have not been able to attach any LUNs to this channel (they attach and then timeout). Our zoning should only allow us to see/discover one port. Sep 19 20:58:45 edidb2prd1

Re: Having issues attaching to LUNs after Brocade mode change

Chris, Have you tried to force the zfcp channels to do a port login (i.e. plogi)? After changing the brocade interopmode, you must do this, otherwise your system is probably trying to use it's previous port id mappings, which the interopmode change changes. Peter -Original

Re: Having issues attaching to LUNs after Brocade mode change

on this list, there are many many different target WWPNS. Is it possible that these are what your linux guests can actually see at the moment? If that’s the case then your zonning does allow to see all of these despite of what you have said. Otherwise where linux would get these wwwpns from?

Re: Having issues attaching to LUNs after Brocade mode change

We have shutdown, deactivated the LPAR, activated and IPLd z/VM and are still having issues. Would it help to offline the FCP port on the HMC? It looks like it attaches and then timesout. Sep 20 23:13:12 omgdb2prd1 multipathd: 8:32: mark as failed Sep 20 23:13:12 omgdb2prd1 multipathd:

Unusable Path Messages from DM-MPIO on Sles11 SP4 Guest

Hi, I have been running IOZONE tests to 32 LVM volumes with ext2 filesystems on them. I am using a Sles11 SP4 guest on z/VM 6.3. I keep seeing unusable path messages in /var/log/messages from Multipathd. However I don't see any path faults or any other messages indicating

Re: Having issues attaching to LUNs after Brocade mode change

Will, I would try taking the fcp port offline. The physical port is what get's the initial port id and the config offline back online would be the only way, I think, to have the plogi sequence operate correctly. Regards, Peter -Original Message- From: Linux on 390 Port

Re: Having issues attaching to LUNs after Brocade mode change

Scott, Brocade FOS has had a configuration option called interopmode. This option (up until FOS 7.x) allowed you to define the brocade switch/director to operate in an interoperability mode with McData directors/switches. The difference between native brocade mode and mcdata mode meant that

Domino

We have been running Domino (legacy Notes and now Xpages) applications on SuSE successfully on zSeries. Now however am prompted to look at Red Hat on the same platform. Does anyone use Domino on zSeries Red Hat? If so, how satisfied are you with the compatibility, installs etc. Thanks.

NPIV is still in effect and we can get the servers going through another path but we cannot get the backup working. Chris Will Systems Software (313) 549-9729 Cell cw...@bcbsm.com -Original Message- From: Linux on 390 Port [mailto:LINUX-390@VM.MARIST.EDU] On Behalf Of Scott Rohling

Did things change from NPIV to non-NPIV (or vice-a-versa)? Scott Rohling On Mon, Sep 21, 2015 at 12:05 PM, Raymond Higgs wrote: > Hi Chris, > > Config off, on from the HMC will free up the resources that those messages > are talking about, but I don't think it will help.

Re: Having issues attaching to LUNs after Brocade mode change

Changing the interopmode on the brocades from mcdata to brocade (which is what it sounds like was done, to me), DOES change the portid that is assigned during the PLOGI sequence. If the system does not re-login to the fabric and obtain the new portid (port id changes due to the difference in

Ok - seems there is more to know (working path vs. non-working) - when you said brocade mode change -- it's not clear what that means... Scott Rohling On Mon, Sep 21, 2015 at 12:41 PM, Will, Chris wrote: > NPIV is still in effect and we can get the servers going through

Re: Having issues attaching to LUNs after Brocade mode change

Hi Chris, Config off, on from the HMC will free up the resources that those messages are talking about, but I don't think it will help. Based your original email, I think your zoning changed. It looks like everything is in a single, giant zone, and you're running out of resources because all

Is it possible that NPIV got turned on and/or discreet zoning is not set up? Thanks, Chris Burgess Phone: 1-800-445-2588 x42149    1-508-249-2149 Fax: 1-508-497-8027 Email: christopher.burg...@emc.com -Original Message- From: Linux on 390 Port [mailto:LINUX-390@VM.MARIST.EDU]
