2.5 Using VMSKITBLD.COM to Modify a System Disk
b. In response to the following prompt, enter the top-level system directory
for the source disk:
* Enter SOURCE disk top level system directory [default = SYS0]:
In most cases, you can choose the default value [SYS0].
c. In response to the following prompt, enter the name of the target disk:
* Enter TARGET disk name (ddcu:):
d. In response to the following prompt, enter the top-level system directory:
* Enter TARGET disk top level system directory [default = SYS0]:
In most cases, you can choose the default value [SYS0].
When the system displays the dollar sign ($) prompt, the files have been
copied and the system disk is complete. VMSKITBLD automatically
dismounts the target disk.
Example
* Enter mounted SOURCE disk name (ddcu:): SYS$SYSDEVICE:
* Enter SOURCE top level system directory [default = SYS0]:
Return
* Enter TARGET disk name (ddcu:): DUA0:
Return
* Enter TARGET disk top level system directory [default = SYS0]:
Return
%DCL-I-ALLOC, _DUA0: allocated
%MOUNT-I-MOUNTED, VAXVMSRL5 mounted on _DUA0:

2.5.3 Using VMSKITBLD.COM to Add an Alternate System Root Directory
Use the ADD option to create an alternate system root directory on a target
system disk. You might use this option to create a test environment where you
can test software without interfering with the current version of the system.
The system disk that you are adding to cannot be in use.
Note
Do not use the ADD option to create a system root to add a new
system to an OpenVMS Cluster environment. Instead, use the
SYS$MANAGER:CLUSTER_CONFIG.COM procedure.
The ADD option creates only new specific root directories. The current common
directory is linked to the new root.
How to Perform This Task
1. Log in to the SYSTEM account.
2. Check the number of free blocks on the system disk to make sure you have
adequate space for the new files, including SWAPFILE.SYS, PAGEFILE.SYS,
and SYSDUMP.DMP. The sizes of these files are determined by the type of
computer you use. For information about calculating size for page, swap, and
dump files, see Section 16.4.
3. Make sure the target system disk is dismounted and on line.
