Article 156984 of comp.os.vms:
>I'm in the process of resurrecting an Alpha 4710, previously
>vendor-maintained. This system has both SCSI and DSSI disks.
>The SCSI disks, of course, have device names of the form
>"nodename$device", but the DSSI disks have names like 
>"R4W2QS$device". Ugly. 

This is actually correct R4W2QS is the hostname of the IDE (Inteligent Disk/
Drive? Element). By default I think you will find your on disk host will have an
allocation class of 0. To have the device display with leading allocation class
you will need to change the allocation class on the disk as well. To do this on
VAX box with embedded shac's you would do something similar to:

shut the machine down.

>>> show dssi

Find the bus and node number from the display.
Then
>>> set host/dup/dssi/bus:0 0 params
                          ^ ^
                        BUS |
                            NODE NUMBER
PARAMS> SET ALLCLASS 1           !if this is the alloclass of serving host
PARAMS> WRITE

Say yes to initialise the controller.

The disk will now appear as $1$dia0 to VMS.

I think you will find the process will be slightly different on the Alpha.
Check out your Hardware manual's and play with at your OWN RISK (I'm not sure I
would play with this unless your pretty sure you know what your doing).


>I _think_ the answer is to set ALLOCLASS, which I did, and the SCSI
