Editting the systables always brings some risks along.
To move devices, you can use device-mirroring.
Enable device-mirroring using sp_configure "disable disk mirroring", 0 (requires a restart of ASE).
Make a mirror of the device using
Code:
disk mirror
name = "device_name" ,
mirror = "physicalname"
[, writes = { serial | noserial }]
Then, when the device is mirrored, unmirror the device with
Code:
disk unmirror
name = "device_name"
[ ,side = { "primary" | secondary }]
[ ,mode = { retain | remove }]
Disable the primary side, leaving the secondary side as the new devicelocation.
