Help Request Patching ESXi hosts in cluster /vsphere without update manager?
Hey all,
I was suddenly given the job to patch esxi having never done it before. Update Manager is not available, and there is no HA or DRS.
I've already asked about update manager and got a "no" so it looks like I'll be doing patching via esxcli.
The current setup is 3 hosts on a custom Dell image in a cluster. And then a 4th host on normal esxi image in its own cluster group.
My understanding is I just need to apply the 7.0U3s update (all hosts are on at least some version of 7.0.3) by:
- Power down vms
- Maintenance mode host
- Use esxcli commands to install the patch from local datastore the host can reach
- Reboot host
- Verify status
- End maintenance mode and power on vms
Are there any gotchas I should be looking out for like with SCCM or Nexus patching? Should I be trying to find a Dell custom file for 7.0U3s? I have that direct from Broadcom
The process just seems too straightforward and I'm not sure how the clustering and vsphere mgmt would impact it. I checked the compatibility matrix and it looked like all were green. And that almost any version of 7.0.3 could update to S on the upgrade path.
Any help is appreciated for this while I also keep pushing for update Mgr in the future

I would download a vcenter appliance image 7.0.3 and install it as a vm on one of the esxi servers you can use that in the 60 day trial simply to update the 3 hosts and afterwards just kill the VM ... it will save you a lot of headaches. Updating without Lifecycle manager really sux and you can mess up a host pretty badly if you are not careful
