Disaster Recovery backup auto-starting VMs (but shouldn't)
-
Can you do a
xe vm-param-list uuid=<UUID>on any on the replicated VM that is auto-booting? (the VM on destination, the copy) -
@olivierlambert Here ya go:

Oh okay, you are using disaster recovery and not continuous replication
Sorry I missed that, despite it's in the title 
So there's no blocked operations in DR, at least it seems.
-
@bazzacad The replicated VM has its start operation blocked which means that it cannot automatically power-on.
But, if you force started this replicated VM via XO, it removed the blockage and now the VM will automatically power-on.
-
I just confirmed with tests that Disaster Recovery jobs do indeed set the
blocked-operationsparameter for backed up VMs. As Julien said, did you ever force-start this VM? That would have removedstartfrom theblocked-operationsfield, which is why we don't see it in your param-list, and why it's now being allowed to autostart. -
@fohdeesha
Thanks for the help everyone. I'm 100% sure I did not force start this VM. In fact all of the DR VMs were running. I know my screen shot it only shows 1 running, but I killed the others ASAP before taking the screen shot.
What I think happened is the secondary host crashed, so I rebooted it.
And I see this parameter is set: actions-after-crash ( RW): Restart.
Is it possible that when the host recovers from a crash it sends the signal to the VMs to force restart? I sent you the parameter of the DR VM that did start up date 2021-07-18 (above), but if I list the parameter from the DR VM for the next day 2021-07-19 the block parameter is set:[07:48 VULCAN ~]# xe vm-param-list uuid=e327b268-887d-395a-9665-2509c341df21 uuid ( RO) : e327b268-887d-395a-9665-2509c341df21 name-label ( RW): rivieraVM2 - Daily Disaster Recovery - (20210719T165550Z) name-description ( RW): Windows Server 2016 License Manager & Print Server user-version ( RW): 2 is-a-template ( RW): false is-default-template ( RW): false is-a-snapshot ( RO): false snapshot-of ( RO): <not in database> snapshots ( RO): snapshot-time ( RO): 19700101T00:00:00Z snapshot-info ( RO): disk-snapshot-type: crash_consistent;

No, a crash wouldn't trigger that. The only way to have this happen is:
- to force start the VM in XO
- or remove the
startfromblocked_operationselsewhere, eg via axe
But the first one seems more plausible
action-after-crashdoesn't have a related meaning (it's just that if your VM crashes, it will be restarted by Xen automatically). It's not host related. -
@olivierlambert
Well I just rebooted my secondary host again via iDrac & these DR VMs started up again.
Note, it started 2 of the same one. And I'm 110% sure I didn't force start any of these, just rebooted the host.
-
And those two got any blocked operations in their record?
-
@olivierlambert
No, the 2 DR VMs that auto-started, don't have the blocked-operations set, the other DR VMs from other days do have it set. -
That's the issue. Why they don't have it is the problem/mystery.
Try to check if new replicated VMs got it. If not, I would check if you are correctly up to date.
