Cluster I/O Protocols (CIP) Configuration and Management Manual (H06.16+, J06.05+)

h. Update the form.
i. Wait for about 15 minutes to make sure the system returns to normal operating condition
before updating the backup CLIM.
You have now completed the procedure for upgrading a Storage CLIM. Continue upgrade
operations until all Storage CLIMs are upgraded.
Upgrading IP CLIMs
CAUTION: During this procedure, the IP CLIM loses connectivity.
1. Prepare IP CLIMs for Upgrade (skip if the host system is not running)
This example shows the preparation step for a failover-configured CLIM. If you are performing this
step on a non-failover-configured CLIM or on a CLIM that is part of a multi-line-path Expand
configuration, start with the Abort CLIM step.
a. List the CLIMs.

According to the info display there are six IP CLIMs (N1002541, N1002542, N1002581,
N1002582, N1012581, N1012582).
b. Determine which IP CLIMs are configured as failover pairs and ensure the primary and backup
interfaces are up and their link pulses are up.

This extract shows that N1002541 and N1002582 are configured as a failover pair in
Provider CSAM2, that all failover interfaces have status UP and link pulse UP, and the interfaces
are running on their home CLIM.
NOTE: If the interfaces are not running on their home CLIMs, perform an SCF SWITCH CLIM,
RESTORE command to the CIP subsystem and check again.
c. For a failover-configured CLIM, perform a manual failover.
1. Switch the CLIM activity to the backup CLIM.
> SWITCH CLIM $ZZCIP.N1002582 , FAILOVER
Open connections still exist, okay to continue? Y
NOTE: TCP and SCTP connections are lost during a failover.
2. Ensure the switch worked.
