Szerintem kell.:
! PROTOCOL /value=6001 DEC Maintenance Operation Protocol Dump/Load Assistance
! PROTOCOL /value=6002 DEC Maintenance Operation Protocol Remote Console
! PROTOCOL /value=6007 DEC Local Area VAX Cluster (LAVC) SCA
+ a tobbi
( az elso ketto kozul, lehet hogy csak az egyik kell ??? )

Vagy sikerul vmit segiteni vagy nem. Hirtelen ezt talaltam bookreaderileg:
7.1.5 VAXcluster State Transitions
State transitions occur when a computer joins or leaves a
VAXcluster system. Connection Manager software con-
trols these events to ensure the preservation of data integrity
throughout the VAXcluster system. A state transition's du-
ration and effect on users (applications) are determined
by the reason for the transition, the configuration, and the
applications in use.
Every transition goes through one or more phases, depend-
ing on whether its cause is the addition of a new VAXcluster
member or the failure of a current member. If the transition
is caused by the addition of a new VAXcluster member, the
phases are as follows:
ˇ New member detection - Early in its boot sequence, a
computer seeking membership in the VAXcluster sys-
tem sends messages to current members asking to join
the system. The first VAXcluster member that receives
the membership request acts as the new computer's ad-
vocate and proposes reconfiguring the system to include
the computer. While the new computer is booting, no
applications are affected.
ˇ Reconfiguration - All current VAXcluster members must
establish communications with the new computer. Once
communications are established, the new computer is ad-
mitted to the VAXcluster system. In some cases, the lock
database may be partially rebuilt.
If the transition is caused by the failure of a current
VAXcluster member, the phases are as follows:
