Shadowing Under OpenVMS7.3-2

[VMS Support]

I have an old Alpha server 400/233 that has a SCSI disk rack attatched to it.
I have loaded VMS 7.3-2 and patched to the Update V400 ECO.
I'm trying to create a shadow set so i can test the new mini-merge facility.

However I get the following following when trying to create a shadow set.

$ init dka400: test400
$ mount dka400: test400
%MOUNT-I-MOUNTED, TEST400 mounted on _TST731$DKA400:
$ show dev dka400/full

Disk TST731$DKA400:, device type COMPAQ BD018635C4, is online, allocated,
deallocate on dismount, mounted, file-oriented device, shareable, available
to cluster, error logging is enabled.

%MOUNT-I-SHDWMEMFAIL, _DKA400: failed as a member of the shadow set

Anything I'm missing ?

Left a bit out ...DSA2 never existed prior on this server.

Shadowset members need to have an allocation class
defined. Set the SYSGEN parameter ALLOCLASS to a
non-zero value (you will have to reboot) then use
$ mount dsa2/system/shadow=$111$dka400 test400
(assuming alloclass is 111)

Thanks Dave.

Now works a treat. Always forget the Alloclass....Tut tut ....
