Any risk if we update our EqualLogic firmware from 5.0.2 to 6.0.9 with VMWare 5.0
We had a PS6000XV with firmware 5.0.2 and it is running fine. Recently, one of the harddisk had problem and we call Dell to help change the problem harddisk. In the Equallogic GUI, everything look fine and no error is found. In SAN HQ, it shows critical conditions that our firmware is too old and the hardisk firmware is too new. Dell Support told us to update the firmware. As everything is running fine and we don't want to change yet. 1) As Equallogic GUI had no problem but SAN HQ report ciritical condition, is that we must update the firmware? 2) Is that high risk to update from 5.0.2 to 6.0.9? 3) We are using VMware 5.0. Is there any tuning need done on WMWare or ESX server after upgrade to 6.0.9? 4) Is there anything we need take notice before do the update? Thx for your help. Best Regards, Ivan

Hello,
You are at risk if you stay on 5.0.2. All EQL customers should be running 6.0.9 or greater. There is a small risk of VMFS Datastore corruption otherwise. There have been so many improvements and fixes since 5.0.2.
You will first need to upgrade to 5.2.10, restart the array, then upgrade to 6.0.9, then restart again.
If you have set your disk timeout values per Dell recommendations you should not have any issue during the restart. You should schedule it in a low I/O or maint period for best results. With the firmware downloads is a document on how to set those timeout values. The VMs too need the timeout updated to 60 seconds.
There are no changes need to ESXi do to the firmware change. There are best practices for ESXi + EQL that should be set regardless of EQL firmware version.
Here's a link to that PDF.

The way I usually look at firmware updates is like this:
Do you prefer a scheduled maintenance window where you keep your software, firmware and drivers up to date (to prevent potential issues), or do you prefer unscheduled maintenance windows due to not keeping up with maintenances?
It's similar to changing the oil in your car; you may be able to get a whole lot further without that oil change, but if you then run into a problem, your car will be in the shop a lot longer and it'll cost a lot more than just doing the regular maintenance.

The problem with this analogy is that Dell would charge us the price of a new car for a firmware upgrade, when really it's something that in the automotive world would be covered by a recall (essentially a shortcoming of the product when it left the factory).

The firmware upgrade comes with the maintenance contract, not a separate charge.
