2.5 Using VMSKITBLD.COM to Modify a System Disk
Disk Description
Source disk The disk from which you copy system files. The source disk must be an
existing system disk.
Target disk The disk to which you move the system files.
Caution
Do not attempt to use VMSKITBLD with the current system disk as
the target disk. VMSKITBLD.COM deletes files that are required for a
running system.
2.5.1 Using VMSKITBLD.COM to Build a New System Disk
At some point, you might want to create a new system disk. For example, suppose
that your existing system disk is an RA81 disk. If you purchase a larger RA90
disk and want to use it as your system disk, you could use the VMSKITBLD
BUILD option to build a new system disk on the RA90 disk.
The existing system disk is the source disk. The new disk is the target disk.
Caution
The VMSKITBLD BUILD option initializes the target disk, deleting all of
its previous contents. For information about copying files to an existing
system disk without destroying files, see Section 2.5.2.
If you want to build your operating system on another disk and you are not
concerned about losing the current contents of the target disk, use the BUILD
option as described in the following procedure.
How to Perform This Task
1. If the source disk is not the current booted system disk, boot the operating
system from the source disk.
2. Log in to the SYSTEM account.
3. Make sure the disk is spun up and on line. If you are using a removable disk,
you must also place the disk into the appropriate drive.
4. Enter the following command to invoke VMSKITBLD:
$ @SYS$UPDATE:VMSKITBLD
VMSKITBLD prompts you to choose one of the following options:
* Operation [BUILD,ADD,COPY]?
5. Enter BUILD and press Return.
VMSKITBLD displays messages that either prompt you for information
needed to complete the operation or inform you of the procedure’s status.
a. In response to the following prompt, enter the name of the source disk:
* Enter mounted SOURCE disk name (ddcu:):
