RAID Array 410 to 450 Upgrade
4–2
EK–SM410–UP. A01
4.1.1 Upgrade Prerequisites
Before replacing the RAID Array 410 controller(s) and cache module(s), please review
the following:
•
The RAID Array 450 is supported on Sun Solaris Versions 2.4, 2.5, and 2.5.1. If
necessary, upgrade your operating system before the controller and cache module
upgrade is attempted.
•
Included with the RAID Array 450 Version 5.0 software is the StorageWorks
Command Console (SWCC) Client and Agent. These replace the Sun RAID Array
410 Manager.
•
This procedure documents single controller to single controller upgrades and dual-
redundant to dual-redundant controller upgrades only. To upgrade a single controller
to a dual-controller configuration, first perform the single to single upgrade and then
add the second controller using the procedure described in Chapter 1, Section 1.8 of
the Getting Started RAID Array 450 for Sun Solaris.
•
During this upgrade procedure, do not add, remove, or move any devices. Any
device configuration changes can be made after the upgrade is completed and
verified.
•
Ensure that the RAID Array is operating normally, that is, no failed drives, batteries,
or storagesets.
•
After removing the old controller, return the controller and PC Card in accordance
with the instructions contained in the customer letter found in the RAID Array 450
platform kit.
4.1.2 Tools Required
You need the following tools to remove or replace the controller module:
•
ESD (ElectroStatic Discharge) strap
•
Medium blade screwdriver for module replacement
•
Small blade screwdriver for trilink and external cache battery cable fasteners
4.1.3 Precautions
In general, you should follow routine ESD protection procedures when handling
controller modules and cache modules and when working around the cabinet and shelf
that houses the modules.
Follow these guidelines to further minimize ESD problems:
•
Use ESD wrist straps, antistatic bags, and grounded ESD mats when handling
controllers and cache modules.
•
Obtain and wear an ESD wrist strap on your wrist. Make sure the strap fits snugly.
•
Attach the lead on the ESD strap to a convenient cabinet grounding point.
•
After removing a module from the shelf, place the module into an approved antistatic
bag or onto a grounded antistatic mat.
•
Remain grounded while installing a replacement module.
