WARNING! When HP 3PAR Remote Copy software is configured, direct upgrades performed
directly from all levels of HP 3PAR OS 2.2.4 to HP 3PAR OS 3.1.1 will fail. This holds true for
offline upgrades and instances when HP 3PAR Remote Copy is simply disabled. For these upgrades,
you must first upgrade to HP 3PAR OS 2.3.1 MU5, and only then proceed to upgrade to HP 3PAR
OS 3.1.1 MU2. In addition, you should not enable HP 3PAR Remote Copy between HP 3PAR
StoreServ Storage system running HP 3PAR OS 2.2.4 and other HP 3PAR StoreServ Storage systems
running HP 3PAR OS 3.1.1.

Remote Versus Local Methods for an HP 3PAR OS Upgrade
This section contains information regarding the difference between a remote online upgrade and
a local online upgrade.
Remote HP 3PAR OS Upgrades
Remote HP 3PAR OS upgrades are achieved by utilizing HP’s Remote Operations Service Tools
(RemOps) (for example, via Ethernet or modem). The process used for remote HP 3PAR OS upgrades
depends on the connectivity model allowed for remote upgrades. There are two connectivity models:
Ethernet RemOps Service processor software updates can be downloaded, staged, and
performed remotely through a secure channel.
Temporary RemOps In some cases, customers will temporarily open up connectivity to the
service processor for remote operations for software updates. If
temporary remote operations access can be granted, we will be able
to perform the update remotely.
Local HP 3PAR OS Upgrades
Local HP 3PAR OS upgrades are achieved by utilizing an on-site service representative to perform
the upgrade. Typically, local HP 3PAR OS upgrades are performed when there is no remote
connection to the service processor. Additionally, a local HP 3PAR OS upgrade may be combined
with other on-site activities, such as hardware upgrades or maintenance.
Start-and-Stop Quorum Witness Steps
Before performing an online upgrade to HP 3PAR OS 3.1.3, stop HP 3PAR Quorum Witness, and
restart it upon completion of the upgrade.
