unless your DW application was provisioned from a dedicated disk group, their devices are on "shared" spindles. If you run "symdev show -sid 123 DEVNAME", at the bottom of the output you will see the physical drives where each hyper reside.  For example here is a 8.6G device (not meta), it's raid-5 device (3+1 configuration)   RAID-5 Hyper Devices (3+1):            {            Device : 1053                {                --------------------------------------------------------------                 Disk     DA       Hyper       Member    Spare       Disk                DA :IT   Vol#   Num Cap(MB)  Num Status  Status  Grp#  Cap(MB)                --------------------------------------------------------------                02D:Db   3468    37    2878    1 RW      N/A        0   286102                01C:Db   3444    39    2878    2 RW      N/A        0   286102                15C:Db   3456    39    2878    3 RW      N/A        0   286102                16D:Db   3454    37    2878    4 RW      N/A        0   286102                }            }        }   now you could run "symdisk show -sid 123 2D:DB" and see all the symmetrix devices that reside on that physical drive. Repeat for the rest of the drives.
hello   I have been asked by the DW team if their symm devices created on the dmx-3 share spindles with non data ware house devices. My first inclination is to say no because I am relatively a dmx-3 newbie, however I want to be sure. I know that sharing spindles on the clariion is common if I create luns within the same raid group for different applications and I can check that easily on our CX4-480. Finding this information on the dmx-3 is a mystery to me. I display the disks by disk group, I execute a symdisk list to see the free space on each disk, however, I can't tell how many devices(luns), have data on each disk. If other servers have data defined on the disks used by the DW, then I might to do some shuffling. The devices are standard devices, no bcvs.  Sorry if the answer is obvious, I am just not finding the answers needed.  Thanks!  Admingirl 
Do Meta/hyper devices created on dmx-3 "share spindles" with other devices
