Why not define different Device configurations and then type ALTFILE X;DEV=DISCGP1 

Eg We have DISC defined as all LDEVs 

   23     DISC 
   25     DISC 
    2     DISC 
    3     DISC 
    5     DISC 
    4     DISC 
    8     DISC 
    1     DISC 
   24     DISC 

But there's nothing to stop you defining a sub-group of the above LDEVs 

SHOWDEV DEVGP1 

    2     DISC 
    3     DISC 
    5     DISC 
    4     DISC 

And when you enter the above MPEX command, any segments on devices that aren't in the above list SHOULD get moved across. 

Rememer you can confirm whereabouts the file's segments are located using LISTF <fileset> , 4 

Best of luck !

I do not believe MPEX has ever had that capability.  Some of the
defragmentation tools, such as Defrag-X from Lund, or DSM from Bradmark can
do this, I believe.

Subject: Splitting Ksam XL files on specific mpe disik drives


I have Vesoft version 5.5. Right know my ksam file is spread amongst all the
disks.  To reduce disk traffic contengencies, I wanted move my ksam files
onto specific disks. I tried altfile ksamfile;dev=12,13,14.  It does not
seem to works, but altfile ksamfile;dev=12 will put all of the ksam file on
that specific disk.  I don't think it's a good idea to have a large ksam
file on 1 disk only for performance. I would rather see it on 3 disks.

Is there something I am doing wrong with my Vesoft command or is the version
too old to do such a thing,

Thank You,
