261.0. "boot_reset again" by TOPTEN::KELLER () Wed Apr 30 1997 17:34

                                                                             
            We have a 4 node FDDI cluster with 2 AS2100a's and 2 3000
        mod 300LX's, all running VMS ver7.1.  Everything is working as
        expected except the fact that if we shutdown with an autoreboot
        on the 300LX's, shortly after the VMS banner, the system hangs.
        This occurs on either of the 300LX's.  (The 2100's work fine)
        The "boot_reset" parameter is set to off. If we set that pa-
        rameter to on, meaning "do an init before booting", the system
        comes up fine.  We have been told to change both system boards
        because they are old rev's (they were, I did, but only one, it
        was a rev n, I went to an R, no change).We were at the level of
        microcode requested when we installed VMS 7.1, but have since
        upgraded to a later version (7 I think).  We took a crash dump.
        apparently the Restart Parameter Block is being corrupted but
        no one knows why.
           I just discovered other notes in this conferance regarding
        this issue but one of the reasons we want to leave the parameter
        set to off is the difference in time it takes in booting re-
        sults in a shadow copy as opposed to a merge.  So, do I just
        leave it on and induce a "shadowcopy" each time.

  Enable boot_reset.  (If "off" hurts, don't do it!)

  As for the shadowing, log the IPMT.  (I've seen references to having
  BOOT_RESET OFF in the shadowing-related documentation, but that set
  of documentation is ambiguous...  The display of the OFF value for
  the parameter is in a wildcarded *BOOT* display, and there are no
  other statements around the setting of the value.)
