To duplicate the same configuration as the original switch, configure the new
switch using the paper that has the parameters written on it.

Reboot the switch (
\Utilities\ Reboot
). Refer to Chapter X in the SANcastle
SANman User Guide or Chapter X of the SANcastle CLI O/S User Guide for help.
8
Disconnect the Fibre Channel connections from the old switch and connect them to
the replacement switch, one at a time, starting with the ISL connections.

Check the switch using the procedures in “Verify the SAN”.
This concludes the procedure for upgrading a switch.
Recovering from Power Failure
(Disaster Recovery)
This section describes how to bring up a High Port Count Fabric when all of
the switches are down, for example, what happens when you recover from a
power failure. The procedures in this section assume that the entire fabric is
down, and that the switches in the fabric have been previously configured.
If you are bringing up a new fabric for the first time, where the switches have
not been previously configured, or adding switches or merging SAN islands to
a fabric that is already up and running, refer to Chapters X and X in the
SANcastle SANman User Guide or Chapter X of the SANcastle CLI O/S User Guide
.
