[Info-vax] delay in startup

While I was travelling, power went off for a few hours for 
maintenance.  (This is the first time I have ever experienced planned 
outage and only the second or third unplanned.)  I thought about logging 
in and shutting everything down cleanly, but decided to use it as a hard 
test instead.  Two of three nodes came back up; that was expected since 
the battery in one of the PWS is dead (now I know which one).  Can this 
be replaced by a standard off-the-shelf battery?  Everything else came 
up OK, but I am puzzled by this:

   13-MAR-2012 17:35:38.00 MINNIM 13-MAR-2012 17:38:31.84
   13-MAR-2012 14:46:40.00 JANDER 13-MAR-2012 17:38:59.19

These two lines are generated by the following code:

   $    OPEN/APPEND/SHARE BOOT_HISTORY CLUSTER_MANAGER:BOOT.HISTORY
   $    WRITE BOOT_HISTORY "''F$GETSYI("BOOTTIME")' ''NODENAME' ''F$TIME()"
   $    CLOSE BOOT_HISTORY

The three minutes for MINNIM between booting and writing to the file is
about what I expect.  JANDER waited for MINNIM to boot (quorum is 2), so 
that explains the almost three-hour wait between booting and writing for 
JANDER, but why did MINNIM boot almost three hours after JANDER?  All 
the nodes lost power at the same time.

Relevant system parameters seem to be:

   SHADOW_MBR_TMO                300
   MVTIMEOUT                    3600
   SHADOW_SYS_WAIT               480
   RECNXINTERVAL                  20

all of which are much shorter than three hours.
