Outline for Offline Update Procedure

The following steps are intended to provide SAN administrators a starting point
for creating site-specific procedures.
1. Schedule an outage for all devices attached to the fabric.
2. Back up all data and verify backups.
3. Shut down all hosts and storage devices attached to the fabric.
4. Disable all switches in the fabric.
5. Change the PID format on each switch in the fabric (see
6. Re-enable the switches in the updated fabric one at a time. In a core/edge

For any devices automatically bound by PID, two options exist:
Execute a custom procedure to rebuild its device tree online. Examples
are provided in the
page 155 section of this chapter.
Reboot the device to rebuild the device tree. Some operating systems
require a special command to do this, for example "boot –r" in Solaris.
