VCSA sees same disk when adding second host and errors out

Hi, if you create a thread on the VMware side, they may be able to help in more detail. But I've done some research and I'd like to help as much as I can. I came across this thread on spiceworks. Here the user mentioned "found that the vpxa.cfg file had the wrong IP address for my vCenter server... Because the vpxa.cfg file was corrupted, it caused the service to repeatedly crash..."[SOLVED] VCSA 6.7 - unable to add hosts - VMware Forum (https://dell.to/3UA77Co) and pointed here as a reference. Solved: "A general system error has occurred: Timed out wa... - VMware Technology Network VMTN

Hope that helps!

Thanks for the help. The error I'm getting is the following:

I tried the resolution in the article but it did not help.

sorry to hear that. If it's belong a cluster, Could you check ESXi version same the other hosts in cluster? or some same reason the ESXi has different configuration or settings than other hosts. I believe you already checked the host firewall and network have an issue or not. I would check there is a duplicate datastores might be cause some conflicts. and rescanning the storage on the hosts.

The hosts see each other's datastores is that the issue? Are the host only supposed to see one datastore?

I can add each host to the VCSA but only if they are in separate data centers. It's only when I try to add them both to a cluster under one data center that I get this error.

It’s normal for hosts within the same vCenter Server and datacenter to see each other’s datastores, especially if the datastores are shared among the hosts. However, the issue you’re encountering might be related to the UUID of the datastore being duplicated in the vCenter Server database when you try to add both hosts to a cluster under the same datacenter. You can check and to ensure that multiple hosts do not access the same virtual machine at the same time, VMFS provides on-disk locking. This means that you need to mount the datastore on each host that requires access to it, and use the same LUN ID and signature for the datastore on each host.
