[HECnet] I broke CHIMPY, again...

You will need to set ALLOCLASS (in MODPARAMS.DAT) to non-zero, autogen, and reboot.   Do not use feedback unless the system had been up for at least 24 hours.

This time by adding volume shadowing:

I added the following to MODPARAMS.DAT:

! Volume Shadowing Parameters:
SHADOWING=2             ! Enables phase II shadowing

SHADOW_SYS_DISK=1       ! Enables system disk shadowing

SHADOW_SYS_UNIT=7       ! Specifies 7 as the virtual unit number
                          of the system disk

SHADOW_MAX_COPY=3       ! Specifies that 3 parallel copies can occur at one time

SHADOW_MBR_TMO=10       ! Allows 10 seconds for physical members to fail over
                        ! before removal from the shadow set


Then ran:
@SYS$UPDATE:AUTOGEN SAVPARAMS SETPARAMS FEEDBACK

Rebooted with save feedback, when it comes up, it fails:


**** OpenVMS Alpha Operating System V8.3       - BUGCHECK ****

** Bugcheck code = 00000B14: SHDWREQALLOC, Allocation class is required for shadow set members
** Crash CPU: 00000000      Primary CPU: 00000000      Node Name: CHIMPY
** Supported CPU count:    00000001

** Current PSB ID:            00000001
** Image Name:                  SYSINIT.EXE

Easiest way to fix?
