Upgrading to OS8 - AK8- 2013.1

The upgrade to OS8, AK8 or whatever we are calling it this week was pretty straightforward. It will take some extra time, as it has to perform some one-time jobs the first time it reboots, but it wasn't more than 15 minutes. Your mileage may vary, it's possible on larger systems that it takes longer. There is also a deferred update I will show you down below that you can choose to do right away or later. Once you do that deferred update, you do NOT want to roll back to the previous version, so be warned. 

It's been over 1.5 years since the last major update, so many of you probably have never done one before. The process is just like a minor update, it just takes longer. 

1 Get the update from MOS and unzip it to a folder. Go ahead and upload it and unpack it like normal from your Maintenance-->System screen. I did like how it tried to tell me how much time was left, but the numbers were all over the place, and it was over by the time it was correct.

Now, when you click the arrow to apply the update, the normal health check window appears, but you will notice something extra. That's the 'Deferred Update' choice. You can make it apply as soon as it reboots, or you can manually apply it later. Remember, you do NOT want to rollback after this is applied. I did "Upon Request", click the "Check" button, and if all is well, click "Apply" 

After it installs and reboots, you can look at the command line via serial port or SSH. You will notice a few things are different during this boot-up.

Right after the "Updating ####" section you can see it actually upgrading various services and the SMF repository. This can take around 3 minutes, but if you have a lot of aggragations or IPMP then it could take longer. So relax. You can see mine, below, which went 290 seconds, and then continued upgrading other stuff.

 The upgrade continues, and the screen is pretty obvious.

 When you see it configuring network devices, you're almost done. You can see the new code level, and it's about to go to the login prompt. At that point, you should be able to log back into the BUI.

 Log back into the BUI, and you will see the new version is the current version in Maintenance-->System

Now, let's do the deferred update on the same screen.

You can read about the deferred updates here, and click apply when ready to add them. In this case, it's for the ability to associate multiple initiator groups with a LUN, something we have wanted for some time now, so very cool. Note that ANY other deferred updates you have not applied yet will also apply, as there is no way to pick and choose. Either they all apply or none do. Remember I said not to roll-back to a previous version of the code after you do this? It will let you, but if you do, your LUN operations will fail. No bueno. Don't do it. The deferred upgrades are one-way.

Note that the deferred update does NOT force a reboot. 

Once you apply the deferred updates, the whole deferred update area goes away, and the screen now looks like this. 

Do you want to see something cool right away now in OS8 that you could not do before? There's a lot I will talk about later, but for now, since you're so excited, go to Configuration-->Alerts, and create a new Threshold Alert. Notice the new Capacity threshold alerts, where you can now get emails or create an action when a pool, and project, or a share goes over, say, 80% full. Sweet.
