HP 3PAR Upgrade Pre-Planning Guide

1 HP 3PAR OS Upgrade Overview
This guide provides the following information on HP 3PAR Operating System (HP 3PAR OS) software
upgrades:
• An overview of the online and offline upgrade processes for the HP 3PAR OS
• Prerequisites for online upgrades
• Guidelines for online upgrades
• Planning information needed for online upgrades

• Remote versus local methods of upgrading
The HP 3PAR StoreServ Storage supports two different methods for upgrading the HP 3PAR OS:
online and offline. The upgrades can be performed with a service representative on-site or remotely
(from HP). Remote upgrades require that remote operations are available.
CAUTION: When upgrading HP 3PAR Storage Systems from HP 3PAR OS 3.1.2 MU3 to HP
3PAR OS 3.1.3 MU1 with Remote Copy groups using non-peer persistent VLUNs for Windows
2012 host clusters, the passive node hangs during node restart.
NOTE: The HP 3PAR OS 3.1.x is a 64-bit operating system. Upgrades to the following HP 3PAR
storage systems are supported:
• HP 3PAR F-Class
• HP 3PAR T-Class
• HP 3PAR StoreServ 7000 Storage system
• HP 3PAR StoreServ 10000 Storage system
NOTE: HP recommends updating host drivers to a supported level of the targeted HP 3PAR OS
upgrade version before attempting an online upgrade. This information is available on the HP
Single Point of Connectivity (HP SPOCK) website at:

information.
In addition to this planning document, the HP 3PAR host OS implementation guides are available
