Displays contents of a Common Bitmask Block.
SHOW CBB address
address
The address of the Common Bitmask Block. This is required.
None.
The contents of the specified common bitmask block are displayed: the number of valid bits, the interlock state, the unit size and count, and the current settings for the bits in the bitmask.

This example shows the active-CPU common bitmask block for a single-CPU system.
Displays information about Common Event flag Blocks, also known as Common Event flag clusters.
SHOW CEB [address|/ALL]
address
The address of a common event flag block. Detailed information is displayed for the specified common event flag block.
/ALL
Specifies that detailed information is to be displayed for each common event flag block. By default, a one-line summary is output for each common event flag block.
The contents of one or all common event flag blocks is displayed. In one-line summary format, the address, name, creator process, reference count, current settings for the 32 event flags in the cluster, and the UIC of the cluster are displayed. In detailed format, the address of the cluster's Object Rights Block (ORB) and the count of waiting threads are also displayed, with lists of all associated processes and waiting threads.You cannot specify both an address and /ALL; they are mutually exclusive.
SHOW COMMON_EVENT_BLOCK is a synonym for SHOW CEB.

Displays connection manager and system communications services (SCS) information for all nodes in a cluster.
SHOW CLUSTER {[{/ADDRESS=n|/CSID=csid|/NODE=name}]|/SCS}
None.
/ADDRESS=n
Displays only the OpenVMS Cluster system information for a specific OpenVMS Cluster member node, given the address of the cluster system block (CSB) for the node. This is mutually exclusive with the /CSID=csid and /NODE=name qualifiers./CSID=csid
Displays only the OpenVMS Cluster system information for a specific OpenVMS Cluster member node. The value csid is the cluster system identification number (CSID) of the node to be displayed. You can find the CSID for a specific node in a cluster by examining the CSB list display of the SHOW CLUSTER command. Other SDA displays refer to a system's CSID. For instance, the SHOW LOCKS command indicates where a lock is mastered or held by CSID. This is mutually exclusive with the /ADDRESS=n and /NODE=name qualifiers./NODE=name
Displays only the OpenVMS Cluster system information for a specific OpenVMS Cluster member node, given its SCS node name. This is mutually exclusive with the /ADDRESS=n and /CSID=csid qualifiers./SCS
Displays a view of the cluster as seen by SCS.
The SHOW CLUSTER command provides a view of the OpenVMS Cluster system from either the perspective of the connection manager (the default behavior), or from the perspective of the port driver or drivers (if the /SCS qualifier is used).OpenVMS Cluster as Seen by the Connection Manager
The SHOW CLUSTER command provides a series of displays.
The OpenVMS Cluster summary display supplies the following information:
- Number of votes required for a quorum
- Number of votes currently available
- Number of votes allocated to the quorum disk
- Status summary indicating whether or not a quorum is present
The CSB list displays information about the OpenVMS Cluster system blocks (CSBs) currently in operation; one CSB is assigned to each node of the cluster. For each CSB, the CSB list displays the following information:
- Address of the CSB
- Name of the OpenVMS Cluster node it describes
- CSID associated with the node
- Number of votes (if any) provided by the node
- State of the CSB
- Status of the CSB
For information about the state and status of nodes, see the description of the ADD CLUSTER command of the SHOW CLUSTER utility in the HP OpenVMS System Management Utilities Reference Manual.
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 the SDA is being run.
The cluster failover control block display provides detailed information concerning the cluster failover control block (CLUFCB). 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 ADD MEMBER command of the SHOW CLUSTER utility in the HP OpenVMS System Management Utilities Reference Manual for information about the flags for OpenVMS Cluster nodes.)
If any of the qualifiers /ADDRESS=n, /CSID=csid, or /NODE=name are specified, then the SHOW CLUSTER command displays only the information from the CSB of the specified node.
OpenVMS Cluster 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 OpenVMS Cluster member, storage controller, 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.

This example illustrates the output of the SHOW CLUSTER /SCS command.
Displays information about all active connections between System Communications Services (SCS) processes or a single connection.
SHOW CONNECTIONS [{/ADDRESS=cdt-address |/NODE=name |/SYSAP=name }]
None.
/ADDRESS=cdt-address
Displays information contained in the connection descriptor table (CDT) for a specific connection. You can find the cdt-address for any active connection on the system in the CDT summary page display of the SHOW CONNECTIONS command. In addition, CDT addresses are stored in many individual data structures related to SCS connections. These data structures include class driver request packets (CDRPs) and unit control blocks (UCBs) for class drivers that use SCS, and cluster system blocks (CSBs) for the connection manager./NODE=name
Displays all CDTs associated with the specified remote SCS node name./SYSAP=name
Displays all CDTs associated with the specified local SYSAP.
The SHOW CONNECTIONS command provides a series of displays.The CDT summary page lists information regarding each connection on the local system, including the following:
- CDT address
- Name of the local process with which the CDT is associated
- Connection ID
- Current state
- Name of the remote node (if any) to which it is currently connected
The CDT summary page concludes with a count of CDTs that are free and available to the system.
SHOW CONNECTIONS next displays a page of detailed information for each active CDT listed previously.
