Starting with MPE release 7.5, generic device ids have been
added to the IODFAULT file to help facilitate the configuration of I/O devices.
The generic IDs are particularly useful for configuring disks,
since they tend to change every few months and their respective
IDs tend to be quite cryptic. Now they need only be identified as
the disk type category.
For disk there are three different types: LVDDISK, HVDDISK, SEDISK.
LVDDISK
low-voltage differential disks
Used on A and
N class machines associated with the A5149A and A5150A adaptor cards
HVDDISK
high-voltage differential disks
Used primarily
on Hawk platforms, but are also available on A and N class machines using
an HVD card; e.g., A4800A or A5159A
SEDISK
single-ended disks
Used mainly by Hawk platforms,
but could be used on an A and N class machine using an LVD bus. However if
SE disks are used on an LVD bus and other LVD devices exist on the
same bus, the performance of the LVD devices is limited by the SE device(s)
For all disk arrays, use HPDARRAY. Products, such as, DVD, CDROM,
and UPS can be configured by simply using the appropriate generic name.
Tape devices fall into one of two categories; i.e., DDS or
DLT (non-DDS) tape products.
The following is the complete generic id list that is located
at the end of the IODFAULT file:
