new at 11i original release
Although the HP-UX 11i install kernel does not include a /stand/system entry for the new 11i driver, hd_fabric, an entry is added to the system file as part of the
installation process on nPartition systems. When the /usr/sbin/mk_kernel command builds a kernel, the hd_fabric driver is then built into the HP-UX kernel.
This only affects nPartition systems. HP-UX kernels built
with hd_fabric present in the system file will not cause compatibility
issues on non-nPartition systems.
Although it is not required for booting HP-UX on hard partitions,
the hd_fabric driver supports partition configuration commands (/usr/sbin/parstatus and others) and related functionality in the Partition
Manager.
