The SASP GWM monitor generates the LB UID from the chassis serial number of the platform on which BIG-IP is running. All vCMP guests running on the platform attempt to use the same UID. The LB UID used to connect to the Server/Application State Protocol (SASP) Group Workload Manager (GWM) is required to be unique for each client connecting to the GWM. As a result, only one vCMP guest running on each BIG-IP appliance or VIPRION chassis is able to successfully use the SASP monitor. - The SASP monitor running on the first vCMP guest can successfully connect to the SASP GWM. - Subsequent SASP monitor instances running on other vCMP guests will fail to connect to the SASP GWM.
The SASP monitor is unable to monitor pool member availability on more than one vCMP guest running on a single BIG-IP appliance or VIPRION chassis.
This occurs when multiple vCMP guests are running on a single BIG-IP appliance or VIPRION chassis, each using a SASP monitor connecting to the same SASP GWM to monitor pool member availability.
The SASP monitor can be used to monitor pool member availability on multiple vCMP guests running on a single BIG-IP appliance or VIPRION chassis.
