sys_attrs_cnx(5)
NAME
sys_attrs_cnx - cnx subsystem attributes
DESCRIPTION
This reference page lists and describes attributes for the connection
manager (cnx) kernel subsystem. Refer to the sys_attrs(5) reference page
for an introduction to the topic of kernel subsystem attributes.
Caution
You should not direct reconfigure the values of these attributes using
the sysconfig utility. Because a healthy cluster requires that there
be a fixed relationship between the attributes and the "on-disk"
values across the cluster, you should use the appropriate tool, such
as the clu_quorum to manage votes, the quorum disk, and quorum.
name
String representing the susbystem name (Connection Manager).
Supported operations: Query
version
Integer representing the connection manager version. A value of 1 is
used for TruCluster Server Version 5.1.
Supported operations: Query
Default value: 1
Minimum value: 0
Maximum value: 2147483647
cluster_name
Name of the cluster.
Supported operations: Query; Configure at boot time
cluster_founder_csid
Cluster system ID (CSID) of the member that formed the cluster.
Supported operations: Query
Minimum value: 0
Maximum value: 2147483647
node_cnt
Number of allocated cluster system blocks (CSBs) known to the
connection manager. The actual number of cluster members will never
exceed this value.
Supported operations: Query
Minimum value: 0
Maximum value: 2147483647
has_quorum
When set to 1, indicates that the local node can see enough votes for
quorum; 0 (zero) otherwise.
Supported operations: Query
Minimum value: 0
qdisk_trusted
When set to 1, indicates that the quorum disk's vote can be counted by
the local member towards quorum. For a member to count a quorum disk's
vote, the member must have a direct connection to the disk, be able to
read and write it, and either claim ownership of it or be a member of
the same cluster as a member that claims ownership.
Supported operations: Query
Minimum value: 0
Maximum value: 2147483647
member_cnt
Number of nodes that are currently cluster members.
Supported operations: Query
Minimum value: 0
Maximum value: 2147483647
current_votes
Number of votes contributed by current cluster members, plus the quorum
disk if it is accessible to the local node and currently claimed by
this cluster.
Supported operations: Query
Minimum value: 0
Maximum value: 2147483647
expected_votes
Number of votes the cluster expects to be present if all configured
nodes and any quorum disk are available, as computed from the
experience of current cluster members.
Supported operations: Query; Reconfigure at run time
Minimum value: 0
Maximum value: 2147483647
quorum_votes
Minimum number of votes required in the cluster for the cluster member
to run.
Supported operations: Query
Minimum value: 0
Maximum value: 2147483647
qdisk_major
Major device number of the h partition on the quorum disk.
Supported operations: Query; Reconfigure at run time
Minimum value: 0
Maximum value: 2147483647
qdisk_minor
Minor device number of the h partition on the quorum disk.
Supported operations: Query; Reconfigure at run time
Minimum value: 0
Maximum value: 2147483647
qdisk_votes
Number of votes the quorum disk contributes towards quorum. The
connection manager uses this value to determine cluster expected votes
and cluster quorum votes.
Supported operations: Query; Reconfigure at run time
Minimum value: 0
Maximum value: 2147483647
mem_seq
Membership change sequence number, or the number of membership
transitions that have occurred since the cluster was formed (including
formation).
Supported operations: Query
Minimum value: 0
Maximum value: 2147483647
add_seq
Member addition sequence number, or the number of membership
transitions caused by nodes joining the cluster (including formation).
Supported operations: Query
Minimum value: 0
Maximum value: 2147483647
rem_seq
Member removal sequence number, or the number of membership transitions
caused by nodes leaving the cluster.
Supported operations: Query
Minimum value: 0
Maximum value: 2147483647
node_id
Member ID.
Supported operations: Query
Minimum value: 0
Maximum value: 2147483647
node_name
Member name.
Supported operations: Query
node_csid
Member cluster system ID (CSID), the unique identifier (re)assigned
each time a node becomes a member of the cluster.
Supported operations: Query
Minimum value: 0
Maximum value: 2147483647
node_votes
Number of votes that this node contributes toward quorum.
Supported operations: Query
Minimum value: 0
Maximum value: 2147483647
node_expected_votes
Number of votes that this node currently expects to be available if all
votes are present. Initially set from /etc/sysconfigtab.
Supported operations: Query
Minimum value: 0
Maximum value: 2147483647
msg_level
CNX message level. A 0 (zero) results in very few CNX messages being
displayed. A 2 gives the most CNX messages. The default is 1.
Supported operations: Query; Configure at boot time; Reconfigure at run
time
Default value: 1
Minimum value: 0
Maximum value: 2147483647
