multiple GUP scenario, SEPM update

This issue has been solved. See solution.

Hello community,

while testing a 12.1 RU1 multiple GUP scenario I noticed that clients without a GUP provided in their subnet are waiting the time defined in the "Maximum time that clients try to download updates from a Group Update Provider before trying the default management server" and then use the SEPM for updates. Seems like if you enable multiple GUP functionality, clients they always wait if for some reason they can't use a GUP.

I thought the "maximum time" is about the client trying to connect to a non-responding GUP but not when there is no GUP provided in the subnet. When there is [EDIT] no [/EDIT] GUP in the subnet the client should use the SEPM immediately.

Question: Is the behaviour intended?

Sylink-log says "[Content] <LuThreadProc---->GUP is in startup wait. Exiting." while waiting.

If you set the max time to say 4 hours, the client will try within that time frame to get updates from the GUP. If it can't after 4 hours, it will get updates from the SEPM. If this is what you're asking than yes this should be intended.

Which GUP do you mean by "the GUP"? There is no GUP on the subnet.

So with this, the client tries to connect to a GUP (even though it's not on the same subnet) and only after the time specified is up, it goes to the SEPM??

No it does not try to connect. Just waits.
Here the Sylink log snippet from client.

Hi,

it is not expected that you assign a LU policy to use the GUP and the GUP is missing for a subnet.

In reality, the clients do not get the list of GUPs you typed in the policy but a dynamic list with the effective GUPs only, hence there's no difference if a GUP is in the list but off or not in the list.

In the SEPM console, create a dedicated group for that subnet and set for it a LU policy to use the SEPM only, this the right way to use the product.

Regards,

Giuseppe

Thanks for clarification :)
Different groups is not an option, but I can activate a GUP in almost every subnet since i got a small server in every one.
