From a Single Virtual Partition

To remove the vPars product, execute the swremove command from the target virtual partition. For example, to remove the vPars product from the partition winona3:

winona3# /usr/sbin/swremove -x autoreboot=true VirtualPartition

The product will be removed, and the virtual partition will be shut down. Because the vPars-specific kernel modifications have been removed, the OS instance cannot be booted again as a virtual partition. However, the OS instance can be booted into standalone mode.

If you are at the console of winona3, use Ctrl-A to toggle to another virtual partition.

CAUTION: Remove the vPars product only at the product level (VirtualPartition). Do NOT remove the vPars product at the bundle level (T1335AC or VPARSBASE). Recommended kernel patches are included in the vPars bundle; if the bundle is removed, these kernel patches will also be removed. For more information on bundles and patches, see the Patch Management Guide for HP-UX 11.x at http://docs.hp.com.
NOTE: When the vPars product is removed, the contents of the AUTO file in the LIF area will be set to the default hpux (where /stand/vmunix is the default argument). This is true even if you have previously modified the AUTO file to contain hpux /stand/vpmon. This replacement occurs on the boot devices associated with the target virtual partition, including the devices listed in /stand/bootconf and the primary and alternate paths of the target virtual partition. See bootconf(4) for more information on the file /stand/bootconf.

From the Entire System

  1. Remove the vPars product from each virtual partition one by one.

  2. After you have removed vPars from the last virtual partition, you will be at the vPars Monitor prompt. At this point, you can type REBOOT to reboot the system.

    MON> reboot

NOTE: On Integrity systems, you will also need to change the mode from vPars to nPars in order to be able to boot in nPars (standalone) mode.

To uninstall VPARMGR or other vPars-related bundles, see “Installing and Removing vPars-related Bundles ”.
