HP-UX Virtual Partitions Administrator Guide (includes A.05.07) (5900-1229, September 2010)

NOTE: Regarding syntax and how vPars commands interpret what is specified on the command
line, see “I/O: Allocation Notes” (page 221). Even if there are shortcuts in assigning LBAs, vPars
assigns per LBA.
In the example below, each LBA (shown in brackets) can be assigned to a different virtual partition.

A system has multiple SBAs, but assignments remain at the LBA levels.

With the addition of cells (an nPartitionable server), there are more SBAs, but I/O assignments
remain at the LBA level:
