A major number refers to a type of device, and a minor number specifies a particular device of that type or sometimes the operation mode of that device type.
Example:
# lsdev -Cc tape rmt0 Available 3F-08-02 IBM 3580 Ultrium Tape Drive (FCP) rmt1 Available 3F-08-02 IBM 3592 Tape Drive (FCP) smc0 Available 3F-08-02 IBM 3576 Library Medium Changer (FCP)
The alt_rootvg_op command can be used to determine which disk is the boot disk for a specific volume group. Use the -q flag to determine the boot disk. This can be useful when a volume group is comprised of multiple disks and a change in the bootlist is necessary.
to clear the Disk pvid and regenerate it:
#chdev -l hdisk2 -a pv=clear #chdev -l hdisk2 -a pv=yes
The following limits are the LVM architectural limits. If LVM Bad Block Relocation is required, then PV sizes cannot be larger than 128 GB. For size limitations of specific storage devices, refer to the storage device documentation.
