AlphaServer SC V2.5 UK1 patch kit 99673

11 April 2003.



This patch contains fixes for the PFS file system issues reported in

the PTRs and/or IPMT cases listed below.



PTR         IPMT       Abstract

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

153-2-1056  CFS.99673  Assert Failed: cp->c_wopncnt == 0

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



You should not need to reboot any nodes to install this patch nor do

you need to build and deploy new kernels. However, you will need to

take all PFS file systems off line temporarily while installing this

patch because pfs.mod cannot be replaced while it is in use.





Summary of fixes:

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



1. Fix for a bug in PFS which could cause CFS to panic because PFS

   was releasing a CFS vnode that was still open. This occurred when

   PFS encountered a problem (e.g. a network error) opening either

   the .pfsbirth or .pfsdeath directory while mounting a file system.

   The panic message would be "Assert Failed: cp->c_wopncnt == 0

   file: cfs_vnops.c:7999, caller: ..."





Prerequisites:

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



This is a UK1 patch and will not work correctly on a V2.5 SSB system.

Instructions:

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



SCV25UK199673 is provided as a setld installable kit. Unpack it

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

/usr/kits/SCV25UK199673 and install it as follows.



First, take all PFS file systems offline. They will need to stay

offline for the duration of the installation.



    # pfsmgr offline all



Once this has completed successfully and the PFS file systems are

offline on all nodes (use "pfsmgr show" to check) configure out

pfs.mod like this:



    # scrun -n all /sbin/sysconfig -u pfs



Now install SCV25UK199673 from the directory you created earlier:



    # cd /usr/kits/SCV25UK199673

    # scrun -d all setld -l /usr/kits/SCV25UK199673 SCV25UK199673



There is no need to build or deploy kernels or reboot any nodes.

Now configure pfs.mod back in and bring the PFS file systems back

on line:



    # scrun -n all /sbin/sysconfig -c pfs

    # pfsmgr online all



Installation is complete at this point.



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



To remove SCV25UK199673 use the following commands:



    # pfsmgr offline all

    (wait for this to finish on all nodes - use "pfsmgr show" to check)

    # scrun -n all /sbin/sysconfig -u pfs

    # scrun -d all setld -d SCV25UK199673

    # scrun -n all /sbin/sysconfig -c pfs

    # pfsmgr online all
