Physical and logical volume errors

There are several common errors with physical and logical volumes that you can troubleshoot.

Hot spot problems
If you notice performance degradation when accessing logical volumes, you might have hot spots in your logical volumes that are experiencing too much disk I/O.
LVCB warnings
A warning results if the LVCB contains invalid information.
Physical partition limits
In the design of Logical Volume Manager (LVM), each logical partition maps to one physical partition (PP). And, each physical partition maps to a number of disk sectors. The design of LVM limits the number of physical partitions that LVM can track per disk to 1016. In most cases, not all of the 1016 tracking partitions are used by a disk.
Device configuration database synchronization
A system malfunction can cause the device configuration database to become inconsistent with the LVM. You can synchronize the device configuration database with the LVM information.
Fixing volume group errors
