I Removing the OpenVMS Operating System
This appendix explains how to remove the OpenVMS operating system from your disk.
You can remove the OpenVMS operating system from your disk in the following ways:
•
If the disk contains a small number of user files, copy those user files elsewhere and then
reinitialize the disk.
• If the disk contains many user files, use the PRODUCT REMOVE command to remove an
obsolete or extra copy of the OpenVMS operating system without removing any of the user
files. You must also delete or archive certain operating system files that the PRODUCT
REMOVE command cannot delete.
NOTE: For systems supporting the Instant Capacity feature, CPU status (how many cores are
available and how much time they have remaining) is not affected by removal of the operating
system from your disk. Such information is stored in NVRAM on the Integrity servers.
Follow these steps to remove OpenVMS operating system files:
1.
If your system disk has multiple system-specific roots, boot the system and execute
SYS$MANAGER:CLUSTER_CONFIG.COM (on OpenVMS Alpha systems) or
SYS$MANAGER:CLUSTER_CONFIG_LAN.COM (on OpenVMS Integrity server systems)
to remove all roots except the one from which you are booted.
2. Shut down and boot from the distribution media or from a system disk other than the one
from which OpenVMS is being removed. Then do one of the following:
•
If OpenVMS is not running from the distribution media, log in to a privileged account.
• If OpenVMS is running from the distribution media, choose the option to execute DCL
commands.
3. Enter the following DCL commands:
$ DEFINE/NOLOG PCSI$SYSDEVICE target-disk
$ DEFINE/NOLOG PCSI$SPECIFIC target-disk:[SYSx.]
$ DEFINE/NOLOG PCSI$DESTINATION target-disk:[VMS$COMMON]
where:
•
target-disk is the device name of the disk from which OpenVMS is being removed.
• SYSx is the root number that you did not remove in step 1.
4. If the disk also contains layered products that were installed using the PCSI utility, HP
recommends that you remove them as well. Remove any layered products before using the
PRODUCT REMOVE VMS command.
Use the following command to remove all the products at once. Select the layered products
you want to remove from the menu.
$ PRODUCT REMOVE * /REMOTE
Use the following commands to remove individual products:
$ PRODUCT SHOW PRODUCT/REMOTE
$ PRODUCT REMOVE product-name /REMOTE
5. Enter the following DCL command:
$ PRODUCT REMOVE VMS /REMOTE
