VMWare host profiles question


Just a quick one as I haven't used them much

A customer has a VMWare cluster, where all of the hosts (qty 4) have recently been replaced.  During the build the consultant doing the work (who has since left) created a "Temp-profile".  They have subsequently left this applied to all of the new hosts and it is now failing on compliance checks.

In the short term I just want to remove the compliance issue

Would I be correct in my thinking that I have the following options which will have the following results

Option 1: - Remove the existing Temp HP from the cluster/hosts - no reboot will be required
Result 1: - The HP will be removed but the risk is if they do reboot they will have the default profile applied?

Option 2: - Remove the existing Temp HP and re-apply a known previous HP - reboot required on all hosts to apply the new profile
Result 2: - Known profile is for older server hardware so likely to cause compliance issues

Option 3: - Leave it as it is.  The customer signs off on applying a new profile.
Result 3: - New reference host profile will need to be built from one of these hosts and then applied to all new hosts.

Option 4: - Adjust the reference HP for the "temp" profile to correct the non-compliance parts and re-apply to correct issues
Result 4: - Would un-applying then editing and then re-applying the "Temp" HP require putting the hosts in maintenance mode or restarting?

Hmmm, not so short after all but there you go - any help appreciated

If you are now responsible for maintaining and supporting this VMware Infrastructure, if we were taking it over, we would scrap, and re-do from scratch.

So Option 3. Create a new Host Profile (although 4 hosts this is borderline, at the effort required!), and apply your supported, best practice host profile to the environment, that you can support and maintain.

Thanks Andrew, that was my preferred option

Out of interest, if an existing HP is removed and edited and then re-applied can that all be done while it is online?  I know removing and applying new profiles requires a reboot but wondered if simple changes required on a profile can be done and rolled out without too much fuss....

Yes, they can but I would not do this to a Production Host, which is hosting VMs.
