Runecast 2.7.0 with ESXi Upgrade Simulator

If you’ve ever had the task to upgrade a number of ESXi servers, you’ll know that it’s a hell lot of work to be done even before you can upgrade the first host. Is the host still on the VMware Hardware Compatibility List (HCL)? Are my PCIe cards (NIC, HBA, SCSI-controller) still supported? Does the current firmware match the future driver?

Finding answers all of these questions might take hours of research. Especially if you have non-uniform clusters.

Runecast got you covered

We have good news for those of you who already use Runecast-Analyzer to scan their cluster against KB issues. The latest beta (2.7.0) of the HW compatibility tool can now simulate host upgrades. Wow cool is that!

Runecast (beta) with Hardware Compatibility Checks

Fully automated VMware HCL checks in Runecast Analyzer

Runecast opened a beta testing program for early adopters to try their latest feature. In a future release of Runecast Analyzer users will not only be able to scan their environment against VMware KB issues, but also to check their hardware against VMware hardware compatibility list (HCL).

I’ve been talking a lot with the Runecast team about this ‘missing’ feature. Now I’m lucky to be one of the beta testers and can get a glimpse to the future. 🙂

The challenge

Getting information about software and configuration issues in your vSphere cluster is priceless. But what about hardware?

Look how a future release of Runecast Analyzer can help. It will check your current hardware configuration against VMware HCL. Continue reading “Runecast (beta) with Hardware Compatibility Checks”

Problem with Emulex OneConnect OCe14000 NIC LoM

Troubleshooting driver, firmware and ESXi version combinations

Hardware failures in vSphere clusters normally aren’t a big issue. Almost every component is redundant in one or the other way. If one component fails, another one will jump in and take over its function. Malfunction is a different thing and more serious than failure. Such a Zombie can become a real problem because as long as there are signs of life, a replacement will not jump in and there will be no failover.

I witnessed such a situation after a scheduled reboot of a Top-of-Rack (ToR) switch. An ESXi host that was connected to the switch with a 10 Gbit uplink became malfunctioning but didn’t fail.

As you can see in the picture, the link indicator and activity LEDs are active although the cable has been disconnected. A true sign that there is something wrong.
