We ran into this issue when rebuilding some hosts.  When trying to vMotion the guests to the newly rebuilt hosts, the vMotion would fail at 82% with the error ”Source detected that destination failed to resume.”

I came across the following article that gave me an idea:  KB: 1006052

The article mentions the following:

Adding a host by these three different methods produces three different UUIDs:

  • hostname
  • hostname.domainname
  • IP.address.of.host

 It appears that the hostname or hostname.domain is also case sensitive.  Mounting a datastore by “DATASTORE.domain.com” will generate a different UUID than “datastore.domain.com”.

Running esxcfg-nas –l on a host will show you the name of the NFS mounts.  ls -l from the /vmfs/volumes directory will show you the UUID of the datastores.

Compare these two hosts:

HOST1
~ # esxcfg-nas -l
<datastorename1> is <path1> from <nas.domain.com> mounted
<datastorename2> is <path2> from <Nas.domain.com> mounted
<datastorename3> is <path3> from <Nas.domain.com> mounted
<datastorename4> is <path4> from <Nas.domain.com> mounted
<datastorename5> is <path5> from <Nas.domain.com> mounted

UUID:  datastorename3 -> 3ba0562f-6ca841f9

HOST2
[root@tevp03187 root]# esxcfg-nas -l
<datastorename1> is <path1> from <nas.domain.com> mounted
<datastorename2> is <path2> from <nas.domain.com> mounted
<datastorename3> is <path3> from <nas.domain.com> mounted
<datastorename4> is <path4> from <nas.domain.com> mounted
<datastorename5> is <path5> from <nas.domain.com> mounted

UUID:  datastorename3 -> 961816a8-7064b2f7

TLDR Version:  Ensure that when mounting datastores you use the same case for the paths across all hosts.

While a nice purple color, not a good way to start a Monday:


Generated on a HP DL580 G7 running ESXi 4.1 U1
Install patch here: HP Sourcing Driver

If patch is already applied, then possible hardware issue. Make sure latest firmware and drivers are installed.

Nothing special, but might be handy.  Were having a few small issues with opening firewall ports and which ones today.  I threw together this doc to help a few other team members.  It is all the ports found in KB1012382 separated by product.

The problem stemmed from a developer adding “Everyone” into the “Guests” group on the server.  Since Windows 2000, Guests are not allowed to view these logs. The fix was simple- remove “Everyone” from [...]
