Several
customers have reported receiving the following error after
installing their 6.2 RTE-A
update:
IO Device error on
LU 1
Reason is: Illegal
request
Request has been flushed
This
error does not occur with 6.1,
nor does it cause any ill
effect on 6.2.
The message occurs on 12040D
muxes which have 5.02 or older firmware
installed. The solution
is to replace the 12040D mux firmware to the latest 5.22 revision, part
number 5181-8682.
How
can I determine exact size
of new SCSI Disks?
The
Hewlett Packard Response Center can give you information regarding the
exact size of many HP supported SCSI drives. However, HP and OEM
SCSI drives are introduced every year, and the information is not
always immediately available. Beginning at RTE-A revision 6.0, you can
use the VSCSI utility on RTE-A to request the total volume size. The VSCSI
command UNITSIZE reports the total number of blocks on a disk unit. In
order to use the VSCSI program on line, you must have at least one LU generated
for the 12016A SCSI interface connected to the SCSI drive in question.
If your system does not currently include any LU’s for the SCSI card, you
can use the memory based system !VSCSI on the RTE-A 6.0 or later Bootables
tape.

How
can I determine what revision level firmware I have on my HP A990 Processor?
The
easiest way to determine the revision is by visually inspecting the part
number of the EPROM in U1913 on the A990 processor and checking it against
the following table:
Octal
Rev. |
Decimal
Revision |
P/N EPROM
U1913 |
| 10 |
8 |
12990-80106 |
| Original Release
of A990 EPROM |
| 11 |
9 |
12290-80111 |
Fixed SR# 4701103903.
All customers
should have been updated
to this rev. |

VCP
fixed to boot from C1701C MO Disk.
See document MF9312300800
for list of other fixes. |
If it is not possible to
physically inspect the processor board, the following procedure will work.
On power up, or after a processor reset, the X-register displays the revision
of the firmware. Use the T command from VCP to display the X-register value:
VCP > %T
The following is a sample
of the registers listed:
P 000000 M 000000 T 000000
RW 000000
A 000012 B 004025 X 000014
Y 000000
Then just compare the value
of the contents of the X-register with the octal value listed in the firmware
revision table above.
