Table A–1 (Cont.) Adjustable Cluster System Parameters
Parameter Description
Cluster System Parameters
A.1 Values for Alpha and VAX Computers
NISCS_CONV_BOOT During booting as an OpenVMS Cluster satellite, specifies whether
conversational bootstraps are enabled on the computer. The default value of
0 specifies that conversational bootstraps are disabled. A value of 1 enables
conversational bootstraps.
NISCS_LAN_OVRHD Starting with OpenVMS Version 7.3, this parameter is obsolete. This
parameter was formerly provided to reserve space in a LAN packet for
encryption fields applied by external encryption devices. PEDRIVER now
automatically determines the maximum packet size a LAN path can deliver,
including any packet-size reductions required by external encryption devices.
NISCS_LOAD_PEA0 Specifies whether the port driver (PEDRIVER) is to be loaded to enable
cluster communications over the local area network (LAN). The default value
of 0 specifies that the driver is not loaded. A value of 1 specifies that that
driver is loaded.
Caution: If the NISCS_LOAD_PEA0 parameter is set to 1, the
VAXCLUSTER system parameter must be set to 2. This ensures coordinated
access to shared resources in the OpenVMS Cluster and prevents accidental
data corruption.
