SHOW CLUSTER
• Number of votes (if any) provided by the node
• Its state
8
• Its status
The cluster block display includes information recorded in the cluster block
(CLUB), including a list of activated flags, a summary of quorum and vote
information, and other data that applies to the cluster from the perspective of the
node for which SDA is being run.
The cluster failover control block display provides detailed information
concerning the cluster failover control block (CLUFCB), and the cluster quorum
disk control block display provides detailed information from the cluster
quorum disk control block (CLUDCB).
Subsequent displays provide information for each CSB listed previously in the
CSB list display. Each display shows the state and flags of a CSB, as well as
other specific node information. (See the Show Cluster utility section of the
OpenVMS System Management Utilities Reference Manual for information about
the flags for VAXcluster nodes.)
VAXcluster as Seen by the Port Driver
The SHOW CLUSTER/SCS command provides a series of displays.
The SCS listening process directory lists those processes that are listening for
incoming SCS connect requests. For each of these processes, this display records
the following information:
• Address of its directory entry
• Connection ID
• Name
• Explanatory information, if available
The SCS systems summary display provides the system block (SB) address,
node name, system type, system ID, and the number of connection paths for each
SCS system. An SCS system can be a VAXcluster member, HSC, UDA, or other
such device.
Subsequent displays provide detailed information for each of the system blocks
and the associated path blocks. The system block displays include the maximum
message and datagram sizes, local hardware and software data, and SCS
poller information. Path block displays include information that describes the
connection, including remote functions and other path-related data.
