This will restore the files under the following directories:

2.2.3.7 Enabling the Version Switch After Installation
Some patches require you to run the versw -switch command to enable the new functions
delivered in those patches. (See the Patch Kit Installation Instructions for information about version
switches.) Enter the command as follows after dupatch has completed the installation process:
# versw -switch
The new functionality will not be available until after you reboot your system. You do not have
to run the versw -switch command, but if you do not, your system will not be able to access
the functionality provided in the version-switch patches.
2.2.3.8 Script Required to Reverse Version Switch
If you enabled version switches as described in the section titled “Enabling the Version Switch
After Installation”, you must run the /usr/sbin/versw_enable_delete script before
attempting to remove Version 5.1B-4. The steps for running this script require a complete cluster
or single system shutdown, so choose a time when a shutdown will have the least impact on
your operations. The following steps describe the procedure:
1. Make sure that all phases of the installation process have been completed.
2. Run the /usr/sbin/versw_enable_delete script:
# /usr/sbin/versw_enable_delete
3. Shut down the entire cluster or the single system.
4. Reboot the entire cluster or the single system.
5. Run dupatch on your single system or on a cluster using the rolling upgrade procedure to
delete Version 5.1B-4 (as described in the Patch Kit Installation Instructions), up to the point
where the kernel is rebuilt and the system must be booted.
6. Reboot the single system or each member of the cluster.
NOTE: This step requires that you reboot each cluster member to remove Version 5.1B-4.
Because the no-roll procedure automatically reboots the system after deleting the patches,
you would not be able to perform this step as required.
2.2.3.9 Restriction on Using No-Roll Procedure to Remove Kit
The section titled “Script Must Be Run When Returning to Pre-Patched System” describes actions
you need to take before rebooting your system if removing this kit would restore your system
