Redundent license Server ?

Can someone please explain the operation of redundant servers with ADLM. I
understand that if the master server is rebooted that one of the subservers
(chosen via IP address) will promote to master. What happens to the clients
connected in this scenario? Should they get the 6-4-2 countdown to shutdown
or should they automatically be picked up by the new master?

Please advise, any info is appreciated.

Thanks,
John A Frampton.

John,

It is common for workstations to see the countdown when the master is
brought down as it takes time for the two remaining servers to promote a new
master and the master to sort things out. During this time, you will see
lots of "Zombie" activity in your AdLM log file if it is set to a high
enough verbosity. Once a master is promoted and the zombies are sorted out,
licenses should be reissued and the countdown stops. Now, where you can run
into problems is if one of your servers is having communication problems it
will remain undetected until the master goes down in which case the pool
will fail and the countdown will go to zero and disconnect the workstation
sessions. This is a very common problem when redundant servers span
multiple network segments (routed or bridged), thus this type of
configuration is not recommended or supported.
