Replacing An Imm-Only Node With Another Node - Nokia 7210 Configuration Manual

Virtual Chassis
Step 7. If the replacement node is a new node, follow these steps.
Step 8. Save the BOF and let the boot proceed.
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
Boot of Nodes in the Stack
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.

iii. Reboot the node by toggling the power button.
iv. On boot up, interrupt the boot process and configure the node as CPM-
IMM (CPM-B) by configuring the following BOF 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
i. Physically connect the new node into the VC ring (the stacking ports
are connected to form a ring so that an alternate path always exists).
ii. Reboot the node.
iii. Connect to the console of the new node.
iv. Power on the node.
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
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.
