AlphaServer SC patch kit:

==========================



AlphaServer SC Version :  SCv2.5 UK1

Kit Name:  T64V51AB21-C0121900-18721-20030529

Release Date: 060303

PTR:  153-2-1127

IPMT Number: CFS.100700

Abstract:    kmf in rfs_find_fsid() on file serving domain





Description of Patch:

=====================

This patch fixes a problem whereby all members of a file

serving domain crash with a kmf in rfs_find_fsid.  The

fix changes rfs_find_clua() to return CLUA_CALL_LOCAL 

instead of CLUA_CALL_DROP and to handle NULL mbufs due to returning

CLUA_CALL_DROP on some other member

1) You have all mandatory patches for this release installed

Instructions:

=============

This patch is provided as an sc_dupatch installable kit.  Unpack it

into a directory that is NFS mounted on all domains e.g.

/usr/cspkit and follow the following steps to install it:





1) Verify that you have the correct version of sc_dupatch (patch installation

   tool) as follows:



    # ident /usr/sbin/sc_dupatch

        $RCSfile: sc_dupatch,v $

        $Revision: 1.2.4.11 $

        $Date: 2003/03/13 10:58:04 $



   The version number should be at least 1.2.4.11. If not, replace it with

   the copy of sc_dupatch specified in Appendix A.2





2) Verify that it is possible to install the patches as follows:



   On the Management Server (if used)



   #/usr/sbin/sc_dupatch -install -kit /usr/cspkit/patch_kit -name <user-name>

    -note  <user-note> -noroll -nolevel2 -noauto -precheck_only -patch all



   On Domains:



   # sra command -domains all -member 1 -command '/usr/sbin/sc_dupatch -install

     -kit /tmp/CSPkit/patch_kit -name <user-name> -note  <user-note> -noroll -nolevel2

     -noauto -precheck_only -patch all'





       Note:

       ======

       if you encounter a message similiar to the following :

             ./sys/BINARY/nfs.mod:

                   its origin can not be identified.



       then,  you will need to run the actual installation (Step 3)

       with the " -deps_only " flag.



       For Example:



       # /usr/sbin/sc_dupatch -install -kit /tmp/CSPkit/patch_kit -name <user-name>

         -note <user-note> -noroll -nolevel2 -noauto -deps_only -patch all



       A full description of -deps_only is provided in Appendix A.1 below:

  

 



3) Now Run the Patch Installation as follows:





  On the Management Server (if Used):

  -----------------------------------



   Install the patch using the following commands:





   #/usr/sbin/sc_dupatch -install -kit /usr/cspkit/patch_kit -name <user-name>

    -note  <user-note> -noroll -nolevel2 -noauto -patch all



   Rebuild your kernel

   # doconfig -c HOSTNAME

   Copy the new kernel to /vmunix

   Reboot the machine

   # shutdown -r now





  On Domains:

  -----------

   Install the patch using the following commands:



   # sra command -domains all -member 1 -command '/usr/sbin/sc_dupatch -install

     -kit /tmp/CSPkit/patch_kit -name <user-name> -note  <user-note> -noroll -nolevel2

     -noauto -patch all'



   Now Build and Deploy the Kernels:

   Make sure all nodes are up so that kernels will be built on all nodes



   # sra command -domains all -member 1 -command 'BuildKernels'

   # sra command -domains all -member 1 -command 'DeployKernels'



   Shutdown the Domains:

   # sra command -domains all -member 1 -command 'shutdown -ch now'



   Now boot All nodes:

   # sra boot -domains all

A.1 Details of -deps_only option

-------------------------------- 



Patches from UNIX support have previously been supplied to AlphaServer SC

customers in a manual install format. That is, patches were installed by the

customer running a script to copy the patch to the correct location. The

standard UNIX support patches for non-SC customers have always been supplied

using the CSP (Customer Specific Patch) format and are installed using the

dupatch tool. Patches for SC customers are now also being provided in CSP

format and these patches need to be installed using the sc_dupatch tool.



sc_dupatch does some dependency checking to ensure the patches already on the

machine are correct. It does this by comparing the chksums of files on the

system with its own dependency list. If you have manually installed a patch

that is on the dependency list for this new patch, then sc_dupatch will report

an error and not install the patch. That is because sc_dupatch is not aware of

patches installed manually.



If sc_dupatch reports an error indicating a failure to install one or more

patches, check whether this error message was generated by sc_dupatch detecting

a mismatch caused by the existence of a manually installed patch.



If you're satisfied that the conflict does arise from a manually-installed

patch which you want to override, then a simple workaround is available in the

form of the new deps_only switch. This has been introduced to cater

specifically for such situations. It turns off the inventory-checking mechanism

so that the pre-install checking is restricted to dependency-checking only.

Simply re-run the install command with the deps_only flag to skip this

inventory check and allow the installation to proceed.
