Dell Unisphere for PowerMax 10.0.1.0 Installation Guide

Before upgrading Unisphere for PowerMax

Prerequisites

NOTE: Before upgrading to Unisphere for PowerMax 10.0.1.0, you need Solutions Enabler 10.0.1.0.

About this task

Ensure that the minimum RAM and disk space requirements for Unisphere for PowerMax are met. For more information about server requirements, see Pre-installation considerations.

If upgrading Solutions Enabler on a Linux platform from a version lower than 9.2.x, you must perform the upgrade only as the root user (that is, the user running the Solutions Enabler daemons). This behavior is because the root user installed Solutions Enabler 9.1. Attempting to perform the Solutions Enabler upgrade as a nonroot user fails.

Upgrades to Unisphere for PowerMax are supported from root to root, or nonroot to nonroot only. The Unisphere for PowerMax Java process runs using the same user account that runs the Solutions Enabler daemons.

Before commencing any upgrade process, ensure that backups of all data have been made.

If any LocalDir accounts have £ or € characters in the password, you must change the password before proceeding with the upgrade to Unisphere for PowerMax 10.0.1.0.

As a safeguard, follow these steps:

Steps

  1. Back up the system database and for each registered storage system, back up the performance database.
  2. Take note of the systems that are registered for collecting performance data. Record the settings for data collection and the diagnostic interval for each system.
  3. Export the Performance settings (metric and alert definitions and user templates). This operation requires setting a password to use when you import the saved settings to the new system.
