HP OpenVMS Systems

Disk Storage Transfers?

» close window

The Question is:

 
Suppose my OpenVMS systems are called A and B. They are not in a VMS cluster so
 they have their own system disks called A_d0 and B_d0. System A has data disks
 A_d1 and A_d2, each with their own volume label as visible in the
 
    $ show device d
 
command. I now want to migrate data disks A_d1 and A_d2 so that they become
 visible under system B. I do not want to lose any data on the data disks. The
 issue is : how to do this ? Here is my plan :
 
1) write down the volume label of each data disk A_d1 and A_d2
2) power down system A
3) hook up physically disks A_d1 and A_d2 to a controller on system B
4) power up system B to the boot prompt (>>>) and do a "show device" to see if
 the disks are visible (no SCSI conflicts, etc)
5) boot system B into OpenVMS and mount the disks one by one using the volume
 label that was used in system A.
 
What do you think ?

The Answer is :

 
  The OpenVMS Wizard suspects you would need to provide rather more
  detail, and particularly detail of the disk hardware and disk
  controllers involved.  Not all disk hardware is easily transportable.
 
  Please contact the Compaq Customer Support Center.
 
  In various cases, a physical transfer of the storage medium does
  involve little more than shutdown and physical relocation of the
  media and (assuming no volume label collisions) a disk MOUNT.
 
  Most commonly, tools such as the OpenVMS utility BACKUP are used
  to relocate the contents of one disk to another disk.
