Hi there,

I added a M6720 cage (HP,DCS1) to an 7400-2 Node today. The online add of the cage was no big deal an went smooth.

This is a showcage after the addition of the cage.

Code: Select all

As you can see, showcage showed to an old firmware. So I did an upgradecage to update the firmware.

Code: Select all

7400-1 cli% upgradecage cage9
Upgrading cage cage9 cpuA from rev 320c to revision in file /opt/tpd/fw/cage/ebod/hp_e6ebd_local_combined_v3.2.0.15.gff.

g b Beginning test after upgrade for cage9
cage9 passed test after upgrade

Now it went wrong... This is a showcage AFTER the firmware update:

One loop is dead, the other IO modules looks spooky. I opened a case at HP and they told me, that there is a known issue with firmware updates, if 2 TB LFF NL SAS drives are installed. Can anyone confirm that or does anyone had the same issue? I have a virtual room meeting tomorrow with a 2nd level engineer to fix this. A soft- and hard reset of the IO modules didn't helped. Cage 4 is also a M6720 (DCS1) with 12x 2 TB 2 TB LFF NL SAS drives running firmware 320f on both IO modules. This cage hadn't any problems, but it was part of the initial setup, so I don't know if a firmware update was made on this cage.

Thanks for advice.

Best regards,
Patrick

I personally haven't seen this in the field, trying to remember whether the last one I did had the 2tb drives or not.

I didn't run the upgradecage command, I thinking ran the admithw command which invokes the firmware upgrade or downgrade depending on what the other shelves are running. I can't imagine the command run would matter.

I'm sure the hp engineer will be able to fix it, if not it sounds like they'll be sending you out some new io modules as failed firmware updates normally end up in useless parts.

There was definitely an issue with 2TB and 3TB drives resolved in a hotfix for either 3.1.2 MU2 or 3, it's been a few weeks since I went through all the release notes. I definitely remember it was supposed to be a hard requirement before adding any NL shelves and was highly recommended if you had NL shelves due to the fact that replacement drives could trigger the issue in existing shelves.

Hello David,

thanks for your reply. That's interesting, because HP states in their Troubleshooting Guide to run upgradecage if an old firmware is on the I/O modules.

@ afidel

Regarding the hotfix: Good information! If I remind correctly, the Customer is running 3.1.2 MU3, so he's maybe affected.

Lets see what HP can do today.

Best regards,
Patrick

Hello,

2nd level solved the problem without replacing the HW. Root login to the StoreServ was necessary. 2nd level ussed a tcli command to reboot the IFC1 (card1). After the reboot, the "dead" IFC0 (card0) came back. Everything looks shiny now.

I guess this highlights the value of getting hp involved with hardware upgrades as the upgrade plan should have highlighted this and the relevant patches installed ahead of time?

I never just add the hardware with first getting hp involved. Not worth the risk on live sans when hp will provide the upgrade plan for you.

Glad it's sorted though.
