parted partition gives empty uuid
Can anyone brief the difference between 'fdisk' partitioning and 'parted' partitioning. Let me explain the problem.
I am using RHEL5.7. My host is configured with Native MPIO. I have created 2 LUNs. I partitioned the first LUN with fdisk (fdisk /dev/mapper/<32bit uuid>), and the second one using parted (parted /dev/mapper/<32bit uuid>). To create parted partition, I executed mklabel gpt; unit s; mkpart primary 64 100%; commands.
Then I executed the kpartx -a /dev/mapper/<32bit uuid> command for both devices, and verified the partition is created with suffix 'p1'. Now if I execute the "dmsetup info -c <32bit uuid>p1", the UUID for the parted partition is returns empty string. But the same is returning a value in fdisk partitioned device.
Any thoughts would be appreciated..
