14.1.4 DEC 7000 console V3.2 and OpenVMS AXP V1.5

Depending on CI and disk numbers, OpenVMS AXP V1.5 may not boot after the console

has been upgraded to V3.2 or higher. The ﬁx is to install a patch to OpenVMS before

upgrading the console.

The patch is on the Alpha AXP System Firmware Update CD, and called [DEC7000]AXPAPB01_

015.A. Install it using VMSINSTAL.

14.1.5 HALT-RESTART problem in VAX V2.x and DEC V2.1 consoles

When the AUTO_ACTION environment variable is set to RESTART and the operating sys-

tems error-HALTs back to console, the console calls a restart routine stored in the HWRPB.

Unfortunately, the console mishandles the program stack and causes another HALT. The

second HALT, while a restart is in progress, causes a reboot. The reboot can result in the

loss of system crash dumps.

Fixed in VAX 7000 V3.0 and DEC 7000 V2.5 console.

14.1.6 Shadowset booting restrictions

There is a restriction with all VAX7000/10000 V2.* console ﬁrmware that when booting from

a controller-based shadow set the physical and virtual unit numbers must be unique. This

restriction is removed with V3.0.

V3.0 uses the mnemonic ’ds’ for controller-based shadow sets and ’du’ for physical drives.

Unfortunately it has another bug which prevents the use of ’ds’ in the BOOTDEF_DEV

string so you cannot setup a V3.0 console to automatically boot from a controller-based

shadow set. Boot nickname ﬁles work OK, but this means the system will not come up after

a crash until someone types >>>Boot "nickname". This is ﬁxed in V3.1.

Use of the boot ﬂags for booting controller-based shadowsets also changed between V2.4 and

V3.0. Up to V2.4 the ﬁrst boot ﬂag only contained the virtual unit number (in HEX) and

a bit to indicate shadow set booting. From V2.6 onwards the ﬁrst ﬂag also contains the

physical unit number. So...

boot -ﬂ 8DAC,2,0 etc. where DAC = virtual unit no. (3500 in DEC)

now becomes

boot -ﬂ 8DAC0000,2,0 etc. where DAC = virtual unit no. and 0000 = physical unit no.

14.1.7 HSC EDC Errors - VAX7000 Console V1.2 Interaction

HSCs which use K.ci1 (HSC70/40/50) can have data buffer descriptor corrupted by V1.2

console code. This results in EDC errors being detected by the HSCs. Temporary ﬁx is to

install following patch, best bet is to upgrade console to V3.0.

This procedure is ONLY for VAX 7000 Systems Console V1.2-1931[A14]

After initing the console, do the following commands:

>>>set mode advanced #following cmd is advanced

>>>set eeprom script powerup #open eeprom script buffer

Script> d 27021 49a2108a #enter deposit cmd

Script> d 271a3 49a2108a #enter deposit cmd
