Only one reply to my question. This came from "Peers, Julie" <julie.peers@capita.co.uk> who made we watch out for moving the disks in the A5200 <quote> Before you go moving any disks from front to back , let me explain about the four quadrants. Each A5200 can be split into 4 quadrants.Each quadrant must have a similar amount of disks in. </quote> I called sun and spoke to an engineer. Sun has software called "Sun storedge traffic manager" which is downloadable with their other san stuff. I couldnt use this as my fcal cards were too old. So I needed to use veritas volume manager. Either of these two bits of software effectively hide the real controllers and presents a virtual controller to the OS. Both controllers would see all disks. However, we have gone the easy way: Each fcal card will see 4 disks in the A5200 in seperate loops. Disksuite will be used to mirror the disks with each 1/2 of each mirror being located on a separate controller. Thanks to all who read sunmanagers.
