Disk or LUN not visible in VM or VMware

The issue and the resolution applies to a scenario where the VM is seeing the C or the primary drive but not the secondary or any other drive.
If you go to VM>edit settings and there is only one disk/boot_disk/primary_disk is present but the other disk(s) is missing and its a windows based VM.
resolution: go to disk management and right click on the disks which are offline and make then online.
background:- After upgrading their Left Hand Network (LHN) from version 8 to 9 one of the windows based VM was not seeing the D partition. The host was ESX 3.5 build 153875 update 4, VI : 2.5 build 227637.
