N/A

Fix Information

A software version that conmtains this fix needs to be installed and running on the vCMP host. The vCMP guest software version doesn't matter in the context of this issue. The changes below will need to be carried out on vCMP host only, and the final step is service affecting, restarting the vCMP guests. To set the rsync connection limit to highest number of guests that blade supports, and so avoid issue of this bug: tmsh modify sys db vcmp.dynamic_rsync_conn_allowed value true (from bash shell) To change back to original default rsync connection limit of four: tmsh modify sys db vcmp.dynamic_rsync_conn_allowed value false The next step is service affecting, and will restart the vCMP guests. If possible failover guests to peers on another vCMP host before carrying out this step. clsh should be used on multi-blade chassis. Restart vcmpd by running 'clsh bigstart restart vcmpd'
