Logical chassis cluster mode discovery
3
• The State column in the Discover Setup - IP dialog shown in Figure 13 applies only to nodes
that are in logical chassis mode. Possible states are:
- Online—A node that is currently connected and operational.
- On discovery, only online members are considered active cluster members. The
Management application server collects the device, port, and LAG information of active
cluster members. The the Management application client displays the member node as a
cluster member in the Ethernet Fabrics topology.
- Offline—A cluster member node that cannot be reached by the primary cluster node.
- On refresh, if the member was an active member of a cluster and is now offline, the
member is marked as missing. If the member is not online after three consecutive short
ticks, auto-discovery gets initiated. If auto-chasing fails, the member remains missing.
- Rejoining—A node that is in the process of rejoining its cluster.
- On refresh, if the member was an active member of the cluster and is now rejoining, then
the member is marked as missing. If the member is not online after three consecutive
short ticks, auto discovery gets initiated. If auto chasing fails, the member remains
missing.
- Replacing—A node that is being replaced.
- On refresh, if a member node is in the Replacing state, the member is shown as missing.
- If the member is in the Replacing state for more than three consecutive short ticks,
auto-discovery gets initiated. If auto-chasing fails, the member remains missing.
Administratively removing a node from a logical
chassis cluster
You can remove a node from a logical chassis cluster by using the Network OS command line
interface. For instructions, refer to the Network OS Administrator’s Guide and the Network OS
Command Reference, versions 4.0 or later.
Once the node is removed, all configurations corresponding to that node are removed from the
cluster configuration database.
The deleted node gets rebooted automatically and boots in VCS-disabled mode.
The deleted node also gets marked as missing in the cluster.
The Management application initiates auto-discovery immediately, and the deleted node gets
rediscovered in its current state.
As an example, Figure 14 shows the Discover Setup - IP dialog box before the administrator
removes a node from the cluster.
