RAID Array 410 to 450 Upgrade
2–2
EK–SM410–UP. A01
•
Included with the RAID Array 450 Version 5.0 software is the StorageWorks
Command Console (SWCC) Agent. The SWCC Agent requires a dedicated
communications LUN for normal operation. This LUN requires only a minimal
amount of storage, 1 block. While it is not difficult to create the communications
LUN, it does require that a device be available. Instructions on how to create the
communications LUN can be found in Chapter 2 of the Getting Started–RAID Array
450 for HP-UX .
•
This procedure documents existing RAID Array 410 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 HP-UX.
•
The controller(s) and all storagesets must be in normal running conditions. Ensure that
the RAID Array is operating normally, that is, no failed drives, controllers, batteries,
or storagesets.
•
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.
•
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.
2.1.2 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
2.1.3 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.
CAUTION
Follow program card guidelines or damage to the
program card and controller software can result.
