3PAR InForm OS 2.3.1 Upgrade Pre-Planning Guide

Release 2.3.1 Upgrade Pre-Planning Guide InForm OS Version 2.3.1

The procedure includes running two scripts:

1 Pre-upgrade script, which performs the following:

◆ Modifies appropriate configuration values.

◆ Generates the post-upgrade script so that the system can be returned to the standard

configuration after the 3PAR InForm OS software update is completed.

2 Post-upgrade script, which sets all appropriate values that were modified in the Pre-

upgrade script back to their original values.

8.0 VMware® ESX Server

Once the InServ Storage Server is upgraded to InForm OS 2.3.1, the VMware ESX Server

Scsi.ConflictRetries parameter should be returned to its default value or 80 on all

VMware ESX servers that connect to the InServ, if previously changed to

200 as directed by

3PAR. InForm OS 2.3.1 contains a fix for the issue in previous InForm OS versions where ESX

SCSI-2 reservation release commands could be delayed by the Sysmgr configuration lock

resulting in virtual machines I/O errors.

9.0 Remote versus Local Methods for InForm OS Update

Read this section for information regarding the difference between a remote online update

and a local online update.

9.1 Remote InForm OS Updates

Remote InForm OS updates are achieved by utilizing 3PAR’s Remote Operations Service Tools

(RemOps) (e.g., via Ethernet or modem). The process used for remote InForm OS updates

depends on the connectivity model allowed for remote updates. There are three connectivity

models:

■ Ethernet RemOps - Service processor software updates can be downloaded, staged, and

performed remotely.

■ Modem RemOps -The service processor software CD can be supplied to the customer to

place in the service processor CD-ROM drive, and the update can be performed remotely.
