Disruptive v6.0.0b firmware upgrades (4100 and 48000)

I just did a firmware upgrade on my fabrics from 5.3.0 to 6.0.0b. It turns out that these were not non-disruptive upgrades - they're supposed to be "no loss of packets and no loss of light". Most if not all of my servers reported the event. About 10 servers reported SCSI errors on their disks and required recoveries (mostly reboots I think). There is no McData gear in the fabric so this should have been a simple upgrade...

In some cases, a host would see the issues on one fabric but not the other, and in other cases, the host would see it on both fabrics (and for the first host I checked that saw it on both fabrics, SCSI I/O errors resulted).

It seems to be upgrades on 4100 edge switches that cause the grief - the upgrades on the directors did appear to be non-disruptive.

Has anybody else done a 5.3.0 to 6.0.0b upgrade? Did you see any issues?

Thanks,

Re: Disruptive firmware upgrades on 4100 switches

I will now add that the firmware upgrades on the 48000 directors were also disruptive.

May 4 06:25:12 horus qla2300: http://ID 647389 kern.info hba1: Fibre Channel Loop is Down (8030)

May 4 06:25:13 horus qla2300: http://ID 726912 kern.info hba1: 2Gb Fibre Channel Loop is Up (8014)

These messages appeared right before the standy CP rebooted. Yes, the standby CP. Sigh...

Something went really wrong with this firmware upgrade...

Hi Ed,

where did they get this Release 6.0.0b ?

This release was replaced by Brocade two week later with the 6.0.0c , actually Release is 6.0.1 and/or 6.1.0a see attached Release Notes, total of 4.

Hi Antonio,

6.0.0b is the latest available from HP. Many customers do not have the option of running whatever Brocade releases - we're stuck with what our OEM supports.

Going from 5.3 to 6.1 wouldn't be an option anyway since Brocade now limits upgrades to a single release version delta instead of 2 releases like they used to - I'd still have to go from 5.3 to 6.0 before I could get to 6.1.

I'm looking at the release notes you included to see if what I ran into is fixed. I haven't found it yet but there's a few pages to read...

Thanks,

.../Ed

Hi Ed,

--->>> Many customers do not have the option of running whatever Brocade releases .....

i agree what you say, but....!

if you get a look in the HP Download, the Rel. 6.0.0b was available for Download of Februar 29, 2008 also more than 2 Week later after 6.0.0c ( GA of Februar 11, 2008 ) was Available by Brocade.

and sincerily, that is a old known problems with HP Guy's then Published for Download a Old Firmware.

It is a same story by HP with Cisco SAN-OS....

Many customers do not have.....

....correct and you hare right, but the customer that have the option to use / and / or runnig "b" can use the next rel. "c" ; "d" and so on, w/o problem, the Letter consist only of Closed Defect by the Actually release.

Re: Disruptive firmware upgrades on 4100 switches

I've gone through the release notes and see nothing to suggest that what I ran into has been fixed. I have no routing, no DCX, no 8Gbps ports.

I'm waiting to hear what HP Engineering has to say for themselves although I expect that they'll probably have to escalate to Brocade.

I am surprised that nobody has said whether they've done an upgrade and had it work as designed.

Upgraded 16 Brocade 4800 directors from 5.3 to 6.0.0c. Only one sw failed with a bad CP0.

Had to replaced CP0 and then install 6.0.0c.

Did HP finally find the problem ?

Re: Disruptive v6.0.0b firmware upgrades (4100 and 48000)

I recently went to 6.1.0c. The upgrade again was disruptive - the ISLs briefly dropped. The vendor is now suggesting it's a hardware problem. The ISLs appeared to work fine before the upgrade, dropped during the upgrade, and are working after the upgrade. That's an odd way for hardware to fail...

Ed,

Any resolution from HP?
