18. On all nodes, update the
/devices
and
/dev
entries.
# devfsadm -C
# scdidadm -C
19. Return the resource groups and device groups that you identified in Step 4 to all
nodes.
# scswitch -z -g
resource-group
-h
nodename
# scswitch -z -D

Replacing a Node-to-Switch Component
Use this procedure to replace a node-to-switch component that has failed or that you
suspect might be contributing to a problem.
Note –
Node-to-switch components that are covered by this procedure include the
following components:
■ Node-to-switch fiber-optic cables
■ Gigabit interface converters (GBICs) or small form-factor pluggables (SFPs) on an
FC switch
■
FC switches
For the procedure about how to replace a host adapter, see “How to Replace a Host
Adapter” on page 44 .
This procedure defines
Node A
as the node that is connected to the node-to-switch
component that you are replacing. This procedure assumes that, except for the
component you are replacing, your cluster is operational.
Ensure that you are following the appropriate instructions:
■
If your cluster uses multipathing, see “How to Replace a Node-to-Switch
Component in a Cluster That Uses Multipathing” on page 42 .
■ If your cluster does not use multipathing, see “How to Replace a Node-to-Switch
Component in a Cluster Without Multipathing” on page 43 .

How to Replace a Node-to-Switch Component in a Cluster
That Uses Multipathing
1. Is your configuration active-passive?
If yes, and the active path is the path that needs a component replaced, make that
path passive.
