[Info-vax] Reconfiguring VMS 6.2 - Shadow set question

[JF Mezei]

On some systems, the SCSI controller makes a hard association between
the SCSI ID of the device and the device name generated under VMS.

Under such a system, DKA300 remains DKA300 even after you have removed
the disk that used to be DKA200.

With regards to DSA devices, you should quickly update the mount command
to remove devices which no longer exist.

Having single member shodowsets doesn't give you much of an advantage
and probably involves a bit more driver overhead.

But before you remove this, you need to inventory your system startup
and other procedures for any direct references to the DSAxxx: devices as
the physical disk device names will change from DSAxxx: to DKAxxx: once
you no longer use shadow sets.
