3PAR InForm OS 2.3.1 Upgrade Pre-Planning Guide

InForm OS Version 2.3.1 Release 2.3.1 Upgrade Pre-Planning Guide

■ All system administration activities must be stopped while performing an Inform OS Online

Update. This includes any provisioning activity, physical/virtual copy activity, and dynamic

optimization. All active tasks must complete or be stopped before proceeding. Be sure to

have the customer stop any automated administration scripts that may be running as well

(Recovery Manager and VSS Provider for Microsoft Windows).

■ For VxVM DMP, depending on the level, the customer should set the link restore interval to

a value of 1 second before starting the online update. This causes the DMP software to

react to the return of missing paths more quickly than it normally would. See the Veritas

DMP and Online Updates section for instructions. After the online update, reset the link

restore interval to the previously configured value. Follow this procedure for each host that

is running VxVM for its DMP.

■ With Windows 2008, using the Microsoft native MPIO driver, the load-balancing policy

defaults to “Active / Passive”. 3PAR requires the load-balancing policy be set to “Active /

Active”. Refer to the 3PAR Implementation Guide for more details on configuring the load-

balancing policy.
