introduction The following is part 2 in a series of simple documents aimed at providing visual guidance on the process required upgrade the FLARE code on an EMC CLARiiON CX4 array. These documents assume that a version of FLARE 30 is already installed on the array, although the steps for FLARE 29 and below are not significantly different. These documents assume that you have access to EMC’s Unisphere Service Manager (USM) on a Windows platform, and that you have downloaded copies of the FLARE code, Recovery Image and Utility Partition Image. These documents are not intended as a replacement for EMC’s official procedure guides, but rather should be used in conjunction with documentation available from Powerlink (http://powerlink.emc.com). You should also refer to http://www.emc.com/cx4support for customized documentation. The normal warnings and caveats apply when upgrading firmware on an array, particularly if it has data on it that is valuable to you. Backup first, and don’t come crying to me if you break something.

process There are 4 basic steps to upgrading FLARE code on a CX4 array:
• Installing / upgrading Unisphere Service Manager (covered in part 1); • Preparing for Installation (covered in part 2) • Upgrading FLARE code (covered in part 3); • Upgrading the Recovery Image (covered in part 4); and • Upgrading the Utility Partition (covered in part 4).
part 2 – preparing for installation In part 1 of this series I covered the installation of USM. You’re obviously keen for more, as you’re still reading. So let’s get to it. In this section we’re going to prepare for the installation of the code on the array. It’s almost as exciting as it sounds. Once you’ve logged into USM successfully, you’ll be presented with the following screen.

Click on the Software tab to get to the bit about software. This includes activities that cover system software, disk firmware and downloads. For the purposes of this activity we’re interested in System Software.

Once you click on System Software you’ll be presented with three choices.

Click on Prepare for Installation and you’ll presented with the wizard’s welcome page. Or whatever it’s called.

Select “Verify storage environment only” and click Next. We’ve already have the software locally, so there’s no need to download it again.

The array verifies that you’re logged onto the array you think you’re logged onto. Trust me, there’s nothing worse than installing code on the wrong array at the wrong time.

You now need to select the software for installation. Click on Browse.
Figure 7 - Software Selection

Select the CX4-Bundle that you downloaded at some stage previously and click Open.

The software is then unpacked.

Once the software is unpacked it’s transferred to the array.

Once the software has been successfully transferred, click on Next.

At this stage there is a manual check required for a number of obscure conditions. Make sure you read them, they’re important.

USM then goes and checks that the hosts attached to the array are capable of failover.

Figure 13 - Server Readiness for Software Update
Sometimes, even though you know the servers are fine, USM won’t be able to accurately gauge the readiness of the servers. Fortunately, there is an Override option, including the standard warning, available to select.

Click Next to proceed.

There is now a diagnostic information step. I generally recommend that you let USM collect the information again.

Go make yourself a coffee, this will take a few minutes to complete.

Once the diagnostic information has been successfully saved to the repository, click Next.

There are a number of rules that are then checked. If any of the checks fail, there’ll be an option to fix it. If it can’t be fixed by USM, you should already be aware of it and talking with your service provider about getting it sorted out before you do the code upgrade.

If there are only warnings, you can proceed with the installation. This is assuming that you’re comfortable that the warnings are nothing to worry about.

At this point it is necessary to select the NDU delay. I suggest you leave this at the default unless you have a good reason to change it. Click Next to continue.

Congratulations, you’re all done! Click Finish to finish this part of the process.
