symdisk list -sid 1234 -by_diskgroup  this command will list disk groups configured on your array, you will see "free capacity column" , that is raw space available on each device, you can run the command below to give you total raw capacity (in this example disk group 0 ..output in gigabytes)  expr `symdisk list -sid 1234 -disk_group 0 |awk '{a += $9};END{print a}'` /  1024  a lot of times there are so many gaps on physical disks that just because it may say that disk groups has so many gigabytes free, when you actually try to create devices it may say "not enough space" so you have to try first.  I am assuming you wanted to present as big volumes as you could create and then create dynamic partition to combine those into one ? Bad idea ..MS Clustering does not support dynamic drives. Do you know why they need 2.5TB drive ..is that just for the database files ?
HI,  I am dmx newbie. I have three years of Clariion Experience however, at my new company I need to do some work on the dmx. I need to present 2.5TB of space from the dmx to our sql team. What is the best way to do that? I know I can only have 255 devices/meta and my device size for raid 5 is approximately 8GB.  Thanks in advance!
