v. On boot up, interrupt the boot process and configure the node as CPM-
IMM node by configuring the following boot loader parameters:
• specify cpm-imm for vc-stack-node-type
• specify the slot number and MAC address of each CPM-IMM node
in the bof vc-stack-node command
Step 8. Save the BOF and let the boot proceed.
The node comes up as a standby CPM node and talks to the active CPM
to start the HA synchronization process. The master LED on the standby
CPM will be blinking. The master LED on the active CPM will glow steady.
Services are not interrupted during the preceding process because the active CPM
(CPM-A) is present and has not been rebooted (assuming the active CPM has an
uplink to the network). If one of the IMM-only nodes was converted to a CPM-IMM
node, the services on that IMM are affected as the node is rebooted to effect the
change to a CPM-IMM node.
5.7.2 Replacing an IMM-only Node with Another Node
In this scenario, it is assumed that the IMM-only node has failed and needs to be
replaced. The replacement node can be a new node from the factory or a node that
has been previously used as an IMM node in another VC. In the former case, the
procedure is similar to adding a node received from factory; see First Time Manual
Boot of Nodes in the Stack starting at Step 9.
The SD card used to boot the node must contain a version of the TiMOS image
(boot.tim) that matches that of the active CPM. If the version do not match, the boot
will not be successful.
If a ring of stacking ports is not configured, any failure in the stack (either a link or
node failure) will isolate some nodes off of the stack, affecting all the services on
those nodes. In addition, if the uplink is available through one of the nodes that is now
isolated or failed, services using the uplink for the entire VC are affected.
The following procedure assumes a ring is configured and that the replacement node
had been previously used as an IMM node in another VC.
Step 1. Disconnect the stacking port of the failed IMM-only node.
Step 2. Connect to the console of the active CPM node.
Step 3. On the active CPM node, use the no vc-stack-node command to remove
the failed IMM-only node configuration from the configuration file of the
active CPM.
