Before the creation of the MPEMXG9 and MPEMXH5 patches, the use of HAFO was
only supported for customers using the XP256 SCSI Disk Array. With these
patches, included in C.75.03, there are significant changes to the HAFO product
including the format of the HAFOCONF configuration file. If you are
updating from 6.5 OR, have not previously installed MPEMXG9 and MPEMXH5 (or
superseding patches), then you will lose your HAFO configuration unless you
follow the steps outlined below.
(The following text is extracted from the new "High Availability FailOver/iX
Manual" for 7.0 and 7.5 which can be found at:
http://docs.hp.com/en/mpeixall.html#MPE/iX%20High%20Availability).
The structure of the HAFOCONF file used by the 7.0 & 7.5 version
(now supporting a number of HP Fibre Channel storage arrays) has changed from
that used by the 6.5 version (for use with XP256 only). BEFORE UPDATING
to 7.0 or 7.5, you should dump the output of the SYSGEN ha> LISTCONF
to an ASCII file.
Then, edit the file down to just the lines that list your LDEVs along with
their primary and alternate paths. This list, with “AD” inserted, can then be
used as the core of an input file for SYSGEN on 7.0/7.5 to create a new
HAFOCONF
For example, a file containing the following commands, passed to SYSGEN as
input, would create a HAFOCONF file with Ldevs 450-453 using the HBA
pair at 0/6/2/0 and 0/6/2/1. These commands also perform the necessary "hold"
and "keep" commands to make this change permanent.

Any MPE/iX Customer using the HAFO product after installing C.75.03 must refer
to the 7.0 and 7.5 HAFO manual rather than the 6.5 version.
