attempted by shutting down all virtual circuits and connections and
reinitializing the port.
|
|
NUM_ERRORS
|
Number of errors that have been logged on the port since the system was
booted. This number includes errors encountered in reinitialization
attempts as well as recoverable errors, such as virtual circuit
failure. This is the same error count as that displayed by the DCL
command SHOW DEVICE.
|
LOCAL_PORTS Class
The LOCAL_PORTS class displays information about the local system
interface to the cluster, such as the name, number, and status of each
port, and the number of entries in the queues associated with each port.

change when the system reboots.
|
|
DIR_WT
|
Lock manager distributed directory weight.
|
|
EXPECTED_VOTES
|
Maximum number of votes that an individual node can encounter. Used as
an initial estimate for computing CL_EXPECTED_VOTES. The cluster
manager sets this number using the EXPECTED_VOTES system parameter. It
is possible for this field to display a number smaller than the
EXPECTED_VOTES parameter setting if the REMOVE_NODE option was used to
shut down a cluster member or the SET CLUSTER/EXPECTED_VOTES DCL
command was used since this node was last rebooted. The dynamic value
for EXPECTED_VOTES used clusterwide is the CL_EXPECTED_VOTES field,
which is described in the CLUSTER class category of ADD (Field).
|
|
PROTOCOL
|
Protocol version number and ECO level of the connection management
software.
|
|
QDVOTES
|
Number of votes the remote system recommends be contributed by the
quorum disk. Normally, the cluster manager sets this number using the
system parameter QDSKVOTES.

|
QF_ACTIVE
|
Indicates whether the remote system's quorum file is accessible.
|
|
QF_SAME
|
Indicates whether the local and remote systems agree about which disk
is the quorum disk.

|
QF_WATCHER
|
Remote system has an active connection to the quorum disk and can
verify its connection for members unable to access the disk directly.
|
|
QUORUM
|
Derived from EXPECTED_VOTES and calculated by the connection manager.
It represents an initial value for the minimum number of votes that
must be present for this node to function. The dynamic QUORUM value is
the CL_QUORUM field, which is described in the CLUSTER class category
of ADD (Field).
|
|
RCVD_SQ
|
Sequence number of the last message received over the OpenVMS Cluster
connection.
|
|
RECNXINTERVAL
|
Displays the time (in seconds) that the connection manager will wait
before timing out the corresponding connection. It is the maximum of
the value contained in the system parameter RECNXINTERVAL on the local
node and the amount of time it would take for the connection manager on
the remote node to discover that the connection is broken.
|
|
SEND_SQ
|
Sequence number of the next message to be sent over the OpenVMS Cluster
connection.
|
|

|
MEMBER
|
System is participating in the cluster.
|
|
NEW

system would normally be a member of the cluster and is displaying NEW
in this field, you can expect that the display will eventually change
to MEMBER.
|
|
NON
|
System is not a member of the cluster.
|
|
REMOVED
|
System has been removed from the cluster.
|
|
|
SW_VERS
|
Indicator of the software version running on the node.
|
|
TRANSITION_TIME
|
Time of the system's last change in membership status. (See the STATUS
field.)
|
|
UNACKED
|
Number of unacknowledged OpenVMS Cluster messages received by the
remote system.
|
|
VOTES
|
Number of votes the remote node contributes toward quorum. Normally,
the cluster manager sets this number with the system parameter VOTES.

|
|
SOFTWARE
|
Name and version of the operating system currently running on the
remote system.

manager sets this number using the system parameters SCSSYSTEMID and
SCSSYSTEMIDH. This number should be the same as the DECnet node number.
|
Qualifiers
None.
Description
The ADD (Field) command enables and adds specific fields of information
to a SHOW CLUSTER display. When you add a field for a class that is not
currently being displayed, the class heading of that field is added to
the display. The qualifier /ALL on any ADD (Class) command adds all
fields in the class to the display.
To remove a field from the SHOW CLUSTER display, enter the REMOVE
(Field) command.
Examples
This command enables the CREDITS class field SEND and adds it to the
SHOW CLUSTER display.
| #2 |
COMMAND> ADD REM_STATE,REM_CONID,LOC_CONID
|
This command enables the CIRCUITS class field REM_STATE and the
CONNECTIONS class fields REM_CONID and LOC_CONID, and adds them to the
SHOW CLUSTER display.
ADD LOCAL_PORTS
Adds all currently enabled LOCAL_PORTS class fields to the SHOW CLUSTER
display.
Format
ADD LOCAL_PORTS
Parameters
None.
Qualifier
/ALL
Specifies that all fields in this class are added to the display.
Description
The ADD LOCAL_PORTS command adds LOCAL_PORTS class information to the
SHOW CLUSTER display. This information includes data for all currently
enabled fields in the LOCAL_PORTS class. By default, the NAME,
LP_STATUS (port status), PORT_NUM (port number), DGS_FREE (free
datagrams queued), MSGS_FREE (free messages queued), OPEN_CIRCS (open
circuits), and FORM_CIRCS (formative circuits) fields are enabled. For
a list of valid LOCAL_PORTS class fields, see the ADD (Field) command.
Use the ADD LOCAL_PORTS command with the REMOVE LOCAL_PORTS command to
turn the display of LOCAL_PORTS class information on and off. If you
remove the LOCAL_PORTS class from the display and add it again without
changing any fields, all of the same fields are displayed again. If,
however, you remove the LOCAL_PORTS class and add new LOCAL_PORTS class
fields, all previously enabled fields are disabled, and only the newly
added fields are displayed.
Examples
| #1 |
COMMAND> ADD LOCAL_PORTS
|
This command adds LOCAL_PORTS class information to the display. This
information includes all enabled LOCAL_PORTS class fields.
| #2 |
COMMAND> REMOVE LOCAL_PORTS
COMMAND> ADD LB_STATUS
COMMAND> REMOVE LOCAL_PORTS
.
.
.
COMMAND> ADD LOCAL_PORTS
|
The ADD LOCAL_PORTS command in this example sequence adds LOCAL_PORTS
class information to the SHOW CLUSTER display. The first command
removes the LOCAL_PORTS class from the display. The second command, ADD
LB_STATUS, adds the LOCAL_PORTS class field LB_STATUS to the display.
As a result, all other LOCAL_PORTS class fields are disabled. When the
LOCAL_PORTS class is removed and added again, only the LB_STATUS field
is displayed.
ADD MEMBERS
Adds all currently enabled MEMBERS class fields to the SHOW CLUSTER
display.
Format
ADD MEMBERS
Parameters
None.
Qualifier
/ALL
Specifies that all fields in this class are added to the display.
Description
The ADD MEMBERS command adds MEMBERS class information to the SHOW
CLUSTER display. This information includes data for all currently
enabled fields in the MEMBERS class. By default, the STATUS field is
enabled. For a list of valid MEMBERS class fields, see the ADD (Field)
command.
Use the ADD MEMBERS command with the REMOVE MEMBERS command to turn the
display of MEMBERS class information on and off. If you remove the
MEMBERS class from the display and add it again without changing any
fields, all of the same fields are displayed again. If, however, you
remove the MEMBERS class and add new MEMBERS class fields, all
previously enabled fields are disabled, and only the newly added fields
are displayed.
Examples
This command adds MEMBERS class information to the display. This
information includes all enabled MEMBERS class fields.
| #2 |
COMMAND> REMOVE MEMBERS
COMMAND> ADD VOTES
COMMAND> REMOVE MEMBERS
.
.
.
COMMAND> ADD MEMBERS
|
The ADD MEMBERS command in this example sequence adds MEMBERS class
information to the SHOW CLUSTER display. The first command removes the
MEMBERS class from the display. The second command, ADD VOTES, adds the
MEMBERS class field VOTES to the display. As a result, all other
MEMBERS class fields are disabled. When the MEMBERS class is removed
and added again, only the VOTES field is displayed.
