Symptom
Message received:
Can not back up /dev/sdb partition since /dev/sda partition has the same identifier.
Cause
fdisk does not correctly write the partition ID when partitioning a disk.
 | Note CDP requires all partitions to have a unique ID even if the partition has not been selected for backup. |
Resolution
A unique partition ID must be created.
 | Warning This is a dangerous operation. Make sure all data has been backed up before changing any partition information on your disk. A failure in changing partition data can make the machine unbootable. |
| Note Some operating systems such as RHEL 5 and Centos use an older version of fdisk contained in the util-linux package, which does not include the ability to change the partition identifier. The util-linux package has been replaced in more updated operating systems with the util-linux-ng package. |
