Overview
The 9 Gigabyte (GB) disk drive has been available since March 1997 as
an embedded disk and as of April 1997 in the mass storage enclosure on
the HP 3000 computer systems. Due to the performance of these disks,
there are special requirements for their use on MPE/iX HP 3000
computer systems. Before installing this disk drive, consider the
following:
1. While the 9 GB disks are supported as an embedded disk, they
cannot be used as LDEV 1 (the boot disk). Therefore, customers
ordering the 9 GB disk as an internal disk must also order a smaller
boot disk such as a 2 GB or 4 GB for the LDEV 1 disk. The 9 GB disk
can then be just another disk in the system domain.
2. Due to a number of differences in technology, the 9 GB disk drive is
only supported on MPE/iX 5.5 and later releases.
Documentation shipped with the disk to help with installation has
information which incorrectly implies that the 9 GB is supported on
MPE/iX 5.0. The patches referenced in the documentation are for
support of the EMC disk array which also uses 9 GB disk drives. The 9
GB disk drive documentation is being changed to state that the current
9 GB disk drive is only supported on MPE/iX 5.5 and later releases.
