A parity group is a disk configuration in which multiple disks
work together to provide redundancy. Synonymous with "array
group."
Dividing a specific physical disk into two or more areas as if
there are two or more physical disks.
Paths are created by associating a port, a target, and a LUN
ID with one or more LDEVs.
Power control interface or peripheral component interconnect.
A physical connection that allows data to pass between a
host and the disk array. The number of ports on an XP disk
array depends on the number of supported I/O slots and the
number of ports available per I/O adapter. The XP family of
disk arrays supports Fibre Channel (FC) ports as well as other
port types. Ports are named by port group and port letter, such
as CL1-A. CL1 is the group, and A is the port letter.
