Hello all guys,
I encountered a very interesting problem here ,I should let u all know , to see if you can help investigate ,
I was upgrade Esxi host from 5.1 U1 to 5.1 U2 build 174xxx .
I attached baseline group to cluster .(20 more hosts).
then scan whole cluster while all cluster were running well .
I found it's was quite slow while scanning . so , I canceled scanning .
now I got some tasks on vsphere client.
1. scanning cluster ....cancelling..
2. cancel scanning ....xx% ,
3.host 01xx upgraded complete .
to see event of host 01xx, I saw a vm on this host was restarted on other host by HA, also have a HA event.
this happened on 3 hosts , and 4 vms were restarted by HA , so I disable HA immediately , then nothing happened.
I want to know , if scan and cancel scan can cause host HA ?
AND WHY THIS HAPPENED.?
Scan should be a very safe action. why it caused VM restarted.
VMware support can't give me a suitable reason.
my cluster enabled HA, admission control , DRS , but no vm monitoring ..
Did anyone of you encounter this ? I need to know WHY!
