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
