1. 5 5 Processing Time For cluster config Might Take Longer On A Head Node With Improved Availability The cluster config utility processing time can take approximately ten minutes longer if it is run on a head node that is configured for improved availability with Serviceguard when the remaining nodes of the cluster are up and running After the entire system has been imaged and booted you might need to re run the cluster config procedure to modify the node configuration If the other node in the availability set with the head node is up and running the Serviceguard daemons attempt to establish Serviceguard related communication with the node when they are restarted Because the other node in the availability set is not actively participating in a Serviceguard cluster it will not respond to the Serviceguard communication The Serviceguard software on the head node retries this communication until the communication times out On a system running with the default Serviceguard availability configuration the timeout is approximately ten minutes 5 6 Notes That Apply To Imaging The notes in this section apply to propagating the golden image to all nodes which is accomplished when you invoke the startsys command 5 6 1 HP Proliant DL140 G3 and DL145 G3 Node Imaging Fails When Graphics Cards Are Present As described in Discovery of HP ProLiant DL140 G3 and DL145 G3 Nodes Fails When Graphics Cards Are Present page 26 the discovery and im2.
