While listing the size of RDM LUNs for a MSCS/WFCS database VM, noticed one LUN's size that i got using a PowerCLI script is different (180GB) than what is listed on vSphere Client devices screen (300GB)....then checked using esxcfg-scsidevs -c |grep naa.id and this shows its size same as vSphere client (300GB)
now checked the associated vm_name-rdmp.vmdk file size and it was same as what i got initially from powercli (180GB)....rvtools is also showing the same.
Note: From inside VM, this is a 300GB RDM Disk
If I understand correctly, in datastore browser RDM pointer file's size (vm_name-rdmp.vmdk) would be listed same as RDM's actual size then why its different here.....Can someone help me here to understand why the same RDM's LUN size is showing differently?
