With any device, it is important to keep up to date with the latest firmware the vendor can offer.
I always check the manufactures websites on a monthly basis to see if anything is new, with this in mind, I was trying to update my P4000 StoreVirtual VSA today and I kept getting the following error message:
‘An error occurred while reading the upgrade configuration file. If the file was from a web connection, click Try Download Again, otherwise recreate your media image’.
A quick check in Help > Preferences > Upgrades I saw that the Download Directory location didn’t look quite right.
So I entered a \ at the end of the Download Directory location
Clicked on OK and started the download again, voila this time it worked!
