Description
Configures the node (MSM) to be online.
Syntax Description
Default
N/A.
Usage Guidelines
The node must be online to participate in leader election and to be selected the primary node.
If the primary node is online and the backup node is offline, the processes on the primary will stop
checkpointing because the backup node is unavailable.
The node priority is part of the selection criteria for the primary node. The lower the priority number,
the higher the priority. The following list describes the parameters used to determine the primary node:
• Node state—The node state must be ONLINE to participate in leader election and to be selected
primary. If the node is in the INIT, OFFLINE, or FAIL states, the node will not participate in leader
election.
• Configuration priority—User assigned priority. The configured priority is compared only after the
node meets the minimum thresholds in each category for it to be healthy.
• Control channel bandwidth—This is a function of the number of links available and the total
bandwidth of these links.
• Software health—Represents the percent of processes available.
• Software version—Represents the software version the node is running.
• Health of secondary hardware components—Represents the health of the power supplies, fans, etc.
• Slot ID—The number of the slot where the node is installed.
• MAC address—The MAC address is used to determine the primary node if all other parameters are
equal.
Example
The following command brings the backup MSM (node) in slot 10 online:
configure node slot 10 online
slot_id Specifies the slot of the node. Slots:
• 1-8 specify I/O modules
• 9-10 specify MSM modules (slot 9 is MSM-A, slot 10 is MSM-B)
node_pri Specifies the priority of the node. The default is 0. The range is 0 to 100.
