HP 2920 Switch – Reboot issue on firmware ver 15.18.0006 #vDM30in30

Updated 25.11.15

Firmware WB.15.18.0007 resolves the issue, see below


A colleague of mine found an issue with the latest HP 2920 switch firmware.
If you create VLANs using the CLI Menu, the switch reboots and the configuration is not saved.

We have reported this to HP, but is currently being treated as a non critical issue as when creating a VLAN via the web interface or native CLI, the issue doesn’t happen.

We have also noticed on this firmware the switch seems to be less responsive. Luckily we had a few units in stock that we could replicate this issue on, and can confirm downgrading to the previous firmware version removes the issue.

A quick cheers to my colleague Marco for finding and researching this issue.

The issue

Switch: HP 2920-48G-POE+

  1.        Go to the Main Menu
  2.        Select (2) Switch Configuration…
  3.        Select (8) VLAN Menu…
  4.        Select (3) VLAN Port Assignment

  7.        Select Save
  8.        Switch reboots and doesn’t save configuration

Hopefully HP will release a fix for this firmware soon, as mentioned we have recreated this issue in production and test.

HP Virtual Connect – Upgrade from version 3.30 to 4.41

Hi,

Only a quick post, but after my last bashing of HP virtual connect. I’ve had to endevour another upgrade for a different customer. This time with two HP chassis that are connected together.

For this customer they are on version 3.30 and need to upgrade to the latest version 4.41.

After speaking with HP support, the suggested upgrade path is;

3.60 / 3.70 / 4.10 / 4.20 / 4.31 / 4.41

For me the each firmware took around 35 to 45 minutes to complete. And you need “Virtual Connect Support Utility 1.11.0” to upgrade to 4.31 and above.

Note: that if you use the vcsu.exe tool and have mutliple flex-10 modules connected together in a domain, the firmware will update all the modules at once, you cannot upgrade just 2 modules of 4, for example.

How to update the Virtual Connect Manager

Note: Please plan downtime for this, as in my case it took everything offline whilst updating both modules.

So to update the Virtual Connect Manager, leave the web interface, as you don’t do it there, you need to download the “Virtual Connect Support Utility”, you can find the latest version here.

To do this, you open up the command interface,

2014-08-13_09-37-45

2014-08-13_09-39-43

As you can see this launches a command prompt in the install area of the utility.

1. Type vcsu.exe and enter

2. Type update and enter

3. Enter the IP address of the Onboard Administrator, username and password.

4. Drag your firmware file from its location into the CMD prompt window and this will automatically out the file location in for you.

4. Click through the options until it says “Initializing, please wait… [Step 1 of 2]”

5. When prompted it will tell you its discovered the Virtual Connect domain, enter the username and password for the Virtual Connect Manager

6. Enter yes after confirming the version you are on and version you are going to.

7. Once done it will tell you its completed and where the log files are loaded.

Here is a full screenshot of the process, with the steps highlighted in yellow with green marks for easy identification.

Things to know about the Virtual Connect Support Utility

it saves everything in your temp location, so where it tells you it’s saved the log, copy the location and open it up

2014-08-13_09-55-181

So it doesn’t just output a file which is the copy of your update session, which in this case is called “vcsu-15044.log”

It saves a copy of your Virtual Connect Manager settings before the upgrade, of which mine was called “vcConfig-8895406-BLE01_vc_domain-201408130822

And finally there is the Support Info output which can be used by HP support to determine the status of your hardware before and after the firmware update “vcSupportInfo-8895406-BLE01_vc_domain-201408130823

If you run the “collect” command, then it produces an output to the temp location for the following files

– Session output

– ShowAll of OA

– ShowAll of Virtual Connect Manager

Deploy a Cisco UCS system – Part 4 – Upgrading the Firmware

My previous posts in the series covered getting the Cisco UCS up and running and into production, and it seems that adding how to upgrade the Firmware on the UCS at the end of the series is best, as you will find yourself needing to do this once the system is in production as well.

Note: Many thanks to Rene again for this simple post helping me through the steps.

Note2: It’s also worth looking through this short article on the do’s and don’t of UCS Firmware updates, from a session held at Cisco Live 2014.

Covered in this post;

  • Pre-reqs
  • Getting the Firmware
  • Upload firmware into UCS Manager
  • Upgrading UCS Manager
  • Upgrading the Fabric Interconnects
  • Upgrading the Blade Servers

HP Chassis and Virtual Connect Firmware Upgrades – Don’t bother

So last night was a busy one thanks to the HP Chassis and “fantastic” Virtual Connect system.

Bare with this article, as its part what happens blah blah, and part, how to install firmware on Virtual Connect

The environment

So the environment consists of;

HP C7000 Chassis

6 x HP BL460c Blade Servers

2 x HP VC Flex-10 Enet Module

These VC Flex modules are connected by 2 x 10GB links in a LACP trunk to Cisco 3750X stack.

The plan of work
