14.1.10 VAX 7000 and HSJ40, Single Path Booting Problem

As described in Section 14.1.11, a VAX 7000 will not boot from an HSJ40 disk if one path

to the HSJ40 controller is disabled. Unfortunately, this conﬁguration is needed as a work-

around for the HSJ40 "dual receive crash" problem.

The following console patch allows the VAX 7000 to boot over a single path. It should only

be installed on systems that boot from an HSJ40 system disk and have console version V3.2-

4041[A6] .Itmust be removed when the console is upgraded. (Use >>> build eeprom, to

erase patch).

Execute the following commands to install the patch.

>>> set mode advanced

>>> set eeprom script powerup

Script> set mode advanced

Script> ka7aa_pwrup

Script> echo "Applying single path boot patch to V3.2-4041[A6]" > tt

Script> d -w 2DBA6 2811 -u

Script> d -l 2dbce 05B13511 -u

Script> d -l 2dbd2 B1471350 -u

Script> d -l 2dbda A0C401E0 -u

Script> d -l 2dbde CA11DA00 -u

Script> Set mode basic

Script> ^Z

>>> Set mode basic

On multi processor systems use this command to update the other CPUs:

P00>>> update ka7aa* -e

This message pops out at Initialise time to tell you the patch is being applied.

14.1.11 VAX 7000 fails to reboot from HSJ-40 devices

VAX 7000 V2.X and V3.0, V3.1 consoles don’t handle the virtual circuit with the HSC-40

properly when attempting to reboot. This causes the boot to fail like this:

P00>>>

Booting...

Connecting to boot device dua403.10.0.13.0

Created device: dua403.10.0.13.0

device dua403.10.0.13.0 not found

failed to open dua403.10.0.13.0

P00>>>

The ﬁx is to install VAX7000 Console V3.2. Note a problem still exists when attempting to

SHOW DEVICE or boot a drive with PATH A or B disconnected or disabled from an HSJ-

40. You must have both paths enabled and connected for the console code to work properly.

Alternatively, see Section 14.1.10.
