HP Tru64 UNIX Version 5.1B-2 and Higher: Patch Kit Installation Instructions > Chapter 2 Preparing for the Installation

Performing a Patch Preinstallation Check

To minimize system down time, you can perform the preinstallation check on a system running in multi-user mode, even if you will perform the actual installation in single-user mode.

The example in this section shows a preinstallation check that results in a patch that fails the check and is prevented from being installed. If this occurs, you would set the system patch baseline, as described in “Creating a Baseline”. If patches are prevented from being installed because dependent patches were not selected, choose the select patches again item and add the required patches that are missing.

If no patches are blocked, you can proceed to the installation phase, as described in Chapter 3 “Patch Installation and Removal Instructions”.

Note that the menu you see will differ slightly, depending upon whether you log in from a pseudo-terminal or a system console. The following steps assume you logged in from a pseudo-terminal.

  1. Log in as root.

  2. From the main dupatch menu, enter 1 at the Enter your choice prompt:

  4. You have the option to make the patches reversible so you can revert the system to its state prior to the installation of a patch. The dupatch utility lists the following information. Press Return at the prompt to make the patches reversible. This is the recommended action.

         ------------------------------------------------------------------------
         To Make Patches Reversible - PLEASE READ THE FOLLOWING INFORMATION:
    
       - You have the option to make the patches reversible so you can 
         revert the system to its state prior to the installation of a patch.  
    
       - Reversibility is achieved by compressing and saving a copy of the 
         files being replaced by the patches. These files would be restored 
         to the system if you choose to delete a patch.
    
       - If you choose to make patches NON-reversible, then the system cannot 
         be restored to the state prior to the installation of a patch; you 
         will not be able to delete the patches later.
    
       - This patch kit may force a small set of patches to be reversible to 
         ensure your upgrades to future versions of Tru64 UNIX are successful. 
         The Patch Utility will make those patches reversible automatically. 
    
         Refer to the Release Notes / Installation Instructions provided with
         this patch kit.
    
    Do you want the patches to be reversible? [y]: y
    
         By default, the backup copies of the installed patches will be saved in
         "/var/adm/patch/backup".
    
         If you have limited space in /var, you may want to make the backup
         directory the mount point for a separate disk partition, an NFS mounted
         directory, or a symbolic link to another file system.
    
         You must ensure the backup directory is configured the same way during
         any patch removal operations.
    
    Your current setup of "/var/adm/patch/backup" is:
    
    	* A plain directory (not a mount point or a symbolic link)

    By default, the backup copies of the installed patches will be saved in /var/adm/patch/backup. If you have limited space in /var, you may want to make the backup directory the mount point for a separate disk partition, an NFS-mounted directory, or a symbolic link to another file system.

  5. Answer yes when asked if you want to perform the preinstallation check with this setup:

    Do you want to proceed with the pre-installation check with this setup? [y]: y
  6. Enter your name and any information that you want to appear in the preinstallation check log:

    Your name: Betty
    
    Enter any notes about this operation that you would like stored for
    future reference (To end your input, enter a "."):
    
    : preinstall check for patch kit 5
    : .
    

  7. The program lists any patches that fail the prerequisite and applicability checks, and asks how you want to proceed. You have the following choices:

    Checking patch prerequisites and patch file applicability...
      (depending upon the number of patches you select, this may take awhile)

    Problem installing:
    
     - Tru64_UNIX_V5.1B / Kernel Patches:
            Patch 26009.00 - SP05 OSFBASE540 (SSRT3631 SSRT3469 SSRT2439 ...)         
    	./usr/sbin/cron: 
    		is installed by Customer Specific Patch (CSP):
    
    			
     - Tru64_UNIX_V5.1B:
            Patch C 00981.00                                                        
    
    		and can not be replaced by this patch. To install this patch,
    		ideally, you must first remove the CSP using dupatch.
    		Before performing this action, you should contact your 
    		HP Service Representative to determine if this patch kit 
    		contains the CSP. If it does not, you may need to obtain a new
    		CSP from HP in order to install the patch kit and retain the 
    		CSP fix.
    		or
    		you may use dupatch baselining to enable the patch installation.
    
    This patch will not be installed.
