On all nodes, remove the obsolete Solaris links and device IDs.
# devfsadm -C
# scdidadm -C
Repeat Step 3 through Step 4 for each node that is connected to the storage array.
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
27 .
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 26 .
■ If your cluster does not use multipathing, see “How to Replace a Node-to-Switch Component in a
Cluster Without Multipathing” on page 27 .

How to Replace a Node-to-Switch Component in a Cluster That Uses
Multipathing
Is your configuration active-passive?
If yes, and the active path is the path that needs a component replaced, make that path passive.
Replace the component.
Refer to your hardware documentation for any component-specific instructions.
(Optional) If your configuration is active-passive and you changed your configuration in Step 1 ,
switch your original data path back to active.
