SAS 9.4 Grid : LSF license renewal

Hi,

 

Its time for software renewal on sas9.4 grid environment with 3 meta nodes 4 compute nodes, 2 management nodes and midtiers

 

when I renew license for LSF the follwoing tech note says I need to restart certain services.(jadmin , badmin , res ans lim) 

 

Tech note : http://support.sas.com/kb/18/638.html

 

can some body confirm on which machine I need to restart these services? is it on metadata server or on management server?.

 

S : $LSF_TOP (lsf instalaltion) directory is accessible from all machines

Re: SAS 9.4 Grid : LSF license renewal

The mentioned service-processes are LSF core processes. The must become aware of the new license and that implies a restart (at OS level) of those. Check your LSF admin docs.  Every node of LSF in the grid (Compute nodes) must be restarted as far I can see. they share the LSF config files. 

If you are uncertain whether the restart is needed. Check the processes are running and the LSf license file is there and changed  than restart. A better appraoch would be to do the restart before changing anything. As those LSF processes are running for a long time anything on the system may have changed making those not startable anymore. When the retart witouth change fails you know you have that trouble to solve. When the restart success and fails after your license change than the license is the troublemaker.

I'm not familiar with SAS GRID, but LSF would be running on all nodes where there is load sharing. That means it could be running on all multi-node tiers. From what you describe that could be ALL nodes.

 

I guess you are running Unix, so I would check for LSF processes running on all nodes (ps -ef?).

Hello @MG18,

 

did you already tried to update the license with RTM and restart every LSF/EGO service? The first service to be restarted should be LIM, which, for our purpose, is the license manager.
