Greetings Community!
Hoping someone with the expertise would help me with the following:
I work in a medium-to-large environment of ESXi hosts managed from over 25 vCenters.
Discovered major time drifts on many hosts due to a number of reasons and corrected them.
To check time sync on a regular basis, did the usual Google thing and found a nice script (posted below) from LucD --Thanks Man--
It works great except that due to various reasons, we have a large number of hosts waiting to be decommissioned that are at the moment either in a Not Responding or Disconnected state.
These, of course, cause the "Unable to communicate with the remote host, since it is disconnected." error and I was wondering how I can make the script run ONLY against hosts "Connected" and in "Maintenance mode". (or ignore hosts NOT in these two connection states)
I could include here a list of things I have been trying for last week or two (without success) but that would make the post too long and risk not being read due to excessive length.
My PoweerCLI skills are not up to par yet hence my request for help.
Thanks a bunch for any and all suggestions!
