We have only 2 esxi hosts and they are almost identical, a Dell Poweredge T630 and a Poweredge R730. on Sunday I updated both from esxi6.7 to 6.7U3. I first updated vcenter appliance to 6.7U3, then each remediated each host using the Dell esxi image VMware-VMvisor-Installer-6.7.0.update03-14320388.x86_64-DellEMC_Customized-A00.iso.
After the update, the T630 seems to be working almost normally (with just a few delays) but the R730 host has much bigger communication delays. Thankfully the VMs appear to be running and working properly. Our issues show up with managing the hosts and backups. The symptoms we’ve seen so far are:
- Our backup server (Veeam backup) is USUALLY UNABLE to successfully scan the R730 host for VMs and disks – it times out. About 5% of the time I try, it succeeds
- Our backup server is USUALLY ABLE to successfully scan the T630 host for VMs and disks. about 5% of the time I test, it fails.
- If I bring up the web based management console to connect directly with the host (not through vCenter server), the first logon attempt always fails (times out), the second attempt always works for the T630 and usually works for the R730 but takes a long time.
- sometimes after the web management interface comes up for R730, it does not correctly disply the hostname in the browser tab.
- Before the update to 6.7 U3 both hosts would successfully login on the first attempt.
- Most of the time the vCenter server appliance (which is currently running on the R730 host) connects to the R730 host.
- SOMETIMES in the web management interface for vCenter Server, It displays the VMs for the T730 host but I cannot shutdown or reboot VMs from the interface. If I connect to the VM via Windows Remote Desktop and shutdown the VM that way, then I can usually see in the vCenter interface that the VM has shutdown, but sometimes it will not even show me the updated state of the VMs
I don’t know where to start with looking in logs. If someone has suggestion I will post logs here
