We have 3 esxi 6.5 build 6765664 host on HP DD580 Gen9 server with vcsa 6.5.
For 6 months we’ve got several time "Another task is already in progress" error on different vms and esxi gave no response to tasks like vmotion or restart managment agents.
There is not any bug on this version of esxi? or any ideas to solve this problem??
In my case, The VM did not have any tasks running. I looked for any background tasks in the command line using VMware KB and did not see any running tasks.
Surprisingly next day it allowed me to perform vmotion and did not give "Another task is in progress" Error.
Our environment is HP Synergy Gen 10 Blades.
I had similar issue. I needed to delete an obsolete VM but was getting this same message. Initially tried
1. several times to shutdown using vCenter : failed
2. logged directly to host and tried shutdown: failed
Since the last operation that I recalled was an attempt to update VMTools., on a hunch I did an eject of the media. Viola ! It completed successfully and the VM was shutdown. I was able to delete the VM thereafter.
My hardware gear was a HPE Synergy 12000 with Gen 10 node
