Re: When will we create parition in a LUN ?

Unfortunately, the term 'LUN' is used for many different things. Some vendors even call a storage container _inside_ a storage array a 'LUN'. And if it is presented to a host, it is another 'LUN', even with a different number.

And stricly speaking, each path to such a container is a SCSI LUN. For example: vmhba1:0:1, vmhba1:1:1, vmhba2:0:1 and vmhba2:1:1 could be 4 different SCSI LUNs. VMware ESX server puts its own multipath handling on top of them, uses a canonical name of vmhba1:0:1 and call it a 'LUN', too.
