unity vsa 5.0 5.2 5.3 and workstation 15 vs 16

Question

hello

the problem i describe now has been occurring for years since workstation version 14 and the latest vsa version.

i have so much unity vsa 5.0 5.2 which work perfectly on esx 6.7u3 and workstation 15.5.6

now i have install version workstation 16.0 and unity vsa stop working:

1) i have not changed the hardware of the vsa
2) i have not change virtual hardware of virtual esx 6.7 "rest hardware 15.5.6"

symptom:
Power on esx 6.7u3 on workstation 16 and vsa 5.2 start perfect.
Shutdown vsa with command service . Start vsa and working perfect. Stop vsa. Start vsa etc etc
but now after 3 4 sequences of stop and start
start vsa and = "Unable to determine serial number" and appear error:
ah01574: module authn_core_module is already loaded, skipping
so:warn pid:21369
now the vsa is lost and only solution is restore vmdk file

the vsa does not become corrupted if it continues to run on 15.5.6

I had the same problem to switch from workstation 14 to workstation 15. And without ever touching the virtual hardware to have as few problems as possible.
Even if I turn up the virtual hardware the problems are always the same.

the only solution that worked is to start vsa on pc1 with workstation 15.xx and esx 6.7u3 and then do the vmotion to esx 6.7u3 on pc2 with workstation 16.
When vsa is on pc2 with workstation 16 : I can shutdown the vsa on pc2 and from this moment it always works on workstation 16. working 100%
now I can also raise the virtual hardware to 16

having two computers the same the first with workstation 15 the second with workstation 16 and doing the vmotion of the vsa is an absurd solution.
And I've already been there. I have many labs with vsa and I can't do this for everything.

another solution is not to install workstation 16
everyone i know had the same problem as me when they went from version 14 to 15.

help me

Hello alvaro99, You will need to open a support case so that we can look into your issue.

hello

I'm doing other tests and other sequences, checking the logs at boot to understand both the serial number error and the ah01574 error. I am checking how emc writes uuid and if this can be altered or that maybe there is interference with the updates. If I have to generate the error ah01574 I can do it simply. I am using the comunity license I don't have "emc support"

HelloI finished doing the tests and I also found a way to make the vsa 5.0.2 5.0.3 go wrong. a) I found the sequence to go from workstation 15 to workstation 16 using only workstation 16 with single pc.This made me solve the problem of unverified serial serial and virtual hardware. so I could also turn up to virtual hardware 16 b) i found the problem of error ah01574:when esx exceeds the version 6.7.0, 15160138 and I do a lot of shutdown and poweron of vsa 5.0.2/5.0.3 the system creates a problem and vsa starts in 'service mode'.To understand this I had to see the starting logs both with error and without error. in this image you can see the correct start   in this image you can see the start with an error that leads to the service mode when you get to service mode: there is no way to recover the vsa, you can just reboot with the reboot gui and it starts working properly. so vsa 5.0.3 has problems with versions above 6.7.0, 15160138 question:is there any way to join the vsa in normal mode without doing it from inside the gui? Sometimes the gui doesn't work and there is no way out of service mode   thanks

ah01574 is an error generated after you modify the VM specs, the Unisphere OS supports on boot only 2 vCPU and 12GB of RAM for community edition.
