Question

Disk firmware update


Hello,
We just received some alerts from our PRISM about the disk firmware. Following the alerts we have to upgrade them.

Info : SATA DOM on host XXXXXX has old firmware version: SATADOM-SL 3IE3 firmware version is S560301N. Need to upgrade to the latest firmware version.

We know that the upgrade do an upgrade one disk at a time but i've some doubts about the process to use before to click to upgrade.

My question is, should we move our VM from the host before to upgrade the disks? should we add our hypervisor in maintenance mode in order to upgrade the disks?
Or the disk firmware update has no impact on VM hosted ?

Thanks in advance all!!!

So it really depends. If you're using AHV, it will evacuate the host before any upgrades occur, you just need to make sure that you've removed any affinity rules for hosts or at least make sure the rules aren't pinning a VM to one host.

If you're using ESXi and don't have DRS, then yes, you'll want to manually evacuate the host and perform a manual upgrade.

I would double check with support about the firmware version. We received a similar alert from NCC on a large number of hosts, and it ended up being a false positive for SATADOM-SL 3IE3. This was resolved with a new version of NCC. If there is a new version available then you can leverage LCM to upgrade.

Hope that helps some.

For more information around LCM you can reference the following:

Hello,

Thank you for your feedback and explanation.

We received these alerts following an upgrade of NCC Check so i supposed we are already in the latest version.

We are not in AHV but in vSphere with DRS Rules.

This is a SATADOM firmware upgrade. The reason you got the alert after upgrading the NCC is because in latest NCC we have introduced the check, to check the SATADOM firmware as well.

The SATADOM contains the Hypervisor, in your case ESXi and can be upgraded through LCM framework. LCM runs pre-checks to verify if DRS is enabled and some additional checks as well before starting the upgrade.

You can leverage LCM and it will upgrade the SATADOM firmware one by one on all nodes.
