vCenter I/O filters upgrade

Post by mohkhalifa »

Dear Guys,
I have a small lab with 2 hosts in a Cluster. Just trying to uninstall the filters and re-install as I added a new host to my cluster. The host which needed to be in maintenance mood is the host which includes the VCSA and Veaam B&R. So, If I put the host in a maintenance mood, all connections will be lost. Also, I can't migrate the VMs to another host for a hardware compatibility issue.
So, How can I upgrade the CDP I/O filters with this scenario ? as I'm getting an error Host can't entered Maintenance mood

Thanks

Hi, Mohammed. Unfortunately, Veeam has no control over I/O filter management operations, as everything is handled by vSphere exclusively. And if vSphere determines that the ESXi host needs to be put into a maintenance mode, then there's no way around this.

I assume you have maintenance windows periodically, these would be a good time to perform Veeam upgrades too. Just treat it the same way as you treat ESXi host upgrades.

Thanks!

Dear Gostev,

Thanks for your reply. But How will I perform the upgrade as the Veeam B&R is a part of the ESXi which means If I put the ESXi in a maintenance mood, then I won't be able to reach the Veeam B&R VM as it's turned-off

Please Advise!

Thanks

Well, I have a much better question for you then: how are you going to restore your backups in case your ESXi host dies? This should be a much bigger concern for you, no?

Basically, the point I am trying to make here is that you've just ran into one of many reasons why deploying Veeam as a virtual machine has always been considered a bad practice. As a rule of thumb, a backup system must never rely in any way on the production system it is designed to protect. While in your case, this production system is literally THE ONLY place backup server can run on!

So, I would highly recommend that you start by moving your backup server to a standalone physical server or workstation. Really, for your environment size even any desktop should do well.

Dear Gostev,

Thanks for your reply and thanks for your recommendations but you must understand from my point of view that everything now is virtual and working with VM is much easier and more controllable than physical machine problems. So, I prefer to use Veeam B&R as a VM which makes me comfortable.

After working-out for my issue, I want your recommendation for this below solution

1- Switching-off all the ESXi VMs
2- Put the desired host into maintenance mode
3- Using ESXi shell commands for:
- esxcli software vib list (to select Veeam CDP filter name)
- esxcli software vib remove -n veecdp (to remove the filters)
4- Putting the host out of maintenance mode
5- Re-check with Veaam B&R filters status and re-install.


What do you think ?

awaiting your kind feedback.

Thanks

Hi Mohamed,

Please refer to the KB4151 for the correct VAIO filter removal procedure.

Thanks

Dear All,

Problem solved by putting the hosts into maintenance mood then installing the VIB veecdp manually to the ESXi with esxcli commands. then putting the host out of the maintenance mood then update the cluster I/O filters from Veeam B&R CDP wizard.

Thanks
