Configuring a UPS-Protected System for the Active Upgrade Process

If your system is protected by a UPS, and you have configured the UPS power
connections as specified in the Express5800/320Ma: Site Planning Guide, it is best to
ensure that the CPU- I ⁄ O enclosure with A-side, UPS-protected power (CPU
enclosure 0, I/O enclosure 10) is marked as the Primary enclosure in ftSMC before
starting the Active Upgrade process.
When you initiate the upgrade process and split the system, the primary (active)
CPU- I ⁄ O enclosure becomes the Production Side of the system. Because the
Production Side controls the upgrade session for most of the Active Upgrade process,
and also contains the most current version of your data disks during the upgrade
process, allowing the Production Side to run on UPS power provides better protection
for your system should power fail during an upgrade.
