I’m currently building a storage solution based on Windows Storage Spaces. I’m using Seagate Enterprise SAS and SSD drives. It’s best practise to install the latest firmware before configuring storage spaces. But what if you have a running setup and there’s a critical firmware update available? Storage Spaces hides the physical drives as the drives are part of the pool on which the virtual disks are created. It’s similar to a traditional RAID solution where accesss to the physical drive is not possible. With traditional RAID solutions however the vendor usually provides a method for upgrading drive firmware while the system is running. Storage Spaces doesn’t have this feature. Most likely because the underlaying hardware can be from different vendors making it hard to create this kind of feature in Storage Spaces. Of course there’s the option of bringing down the system and booting with a DOS or Linux distribution but what you really want is a way to accomplish this without any downtime. In this post I will explain how I did this with my setup using Seagate drives.
