Reforming the Shadow Set

If you have upgraded a disk in a volume shadowing environment, you must now reform the shadow set as follows:

Enter the SHOW DEVICE D command to display a list of disks available on your system. For example:

$ SHOW DEVICE D
Device                Device     Error    Volume       Free  Trans Mnt
 Name                 Status     Count     Label      Blocks Count Cnt
$11$DKB100:  (NODE1)  Online        0  
$11$DKB200:  (NODE1)  Mounted        0      ALPHA070   918150    1  31

Enter a command in the following format:

MOUNT/CONFIRM/SYSTEM DSAn: /SHADOW=(upgraded-disk:,new-member:) volume-label

Note the following conventions:

DSAn: is the virtual unit name of the shadow set.

upgraded-disk: is the name of the shadowed system disk you just upgraded.

new-member: is the name of the disk you want to add as a member of the shadow set.

volume-label is the volume label of the shadowed system disk you just upgraded.

When you reform the shadow set, the contents of the new member are replaced by the contents of the disk you upgraded. Specifying the /CONFIRM qualifier reminds you of this fact, confirming that you are specifying the correct name of a disk that either is blank or contains files you no longer need.

Example

$ MOUNT/CONFIRM/SYSTEM DSA54: /SHADOW=($11$DKB200:,$11$DKB100:) ALPHA0732 
 
%MOUNT-F-SHDWCOPYREQ, shadow copy required 
Virtual Unit - DSA54 Volume label ALPHA0732
     Member                    Volume label Owner UIC
     $11$DKB100:  (NODE1)      SCRATCH      [100,100] 
Allow FULL shadow copy on the above member(s)? [N]: YES
