- Pinja_Sachi_736NimbostratusGetting Error - Issue is the node belongs to a different partition and the pool belongs to a different partion - but the script assumes the pool partition as the node partition... Script works if both pool and node are in the same partition PowerShellPoolMemberAvailability.ps1 -BIGIP 1x.1x.x.x -User xx -Pass xx -Pool bi.dd.com Exception calling "get_object_status" with "1" argument(s): "Exception caught in LocalLB::urn:iControl:LocalLB/PoolMember::get_object_status() Exception: Common::OperationFailed primary_error_code : 16908342 (0x01020036) secondary_error_code : 0 error_string : 01020036:3: The requested Pool Member (/App_Admins/bi.dd.com /App_Admins/1x.x.x.x 80) was not found."

- Pinja_Sachi_736NimbostratusAlso Noticed - Doesnt Work with v11 due to ==> LocalLBPoolMember.get_object_status the v11 supports ==> LocalLBPool.get_member_object_status
