Patch Installation Instructions:
--------------------------------
VRTSvxfs 5.1SP1 patch must be installed first before applying this patch.

For the Solaris 9 release, refer to the online manual pages for
instructions on using 'patchadd' and 'patchrm' scripts provided with
Solaris.  Any other special or non-generic installation instructions
should be described below as special instructions.  The following
example installs a patch to a standalone machine:

       example# patchadd /var/spool/patch/110434-07

The following example removes a patch from a standalone system:

       example# patchrm 104945-02

For additional examples please see the appropriate manual pages.


Special Install Instructions:
-----------------------------
Sun introduced a page ordering vnode optimization in Solaris 9 and 10.
The optimization includes a new vnode flag, VMODSORT, which when turned on
indicates that the Virtual Memory (VM) should maintain the v_pages list
in an order depending on if a page is modified or unmodified.

Veritas File System (VxFS) can now take advantage of that flag,
which can result in significant performance improvements on operations
that depend on flushing, such as fsync.

This optimization requires the fixes for Sun BugID's 6393251 and 6538758
which are included in the Solaris kernel patch listed below.
Enabling VxFS VMODSORT functionality without the correct OS kernel patches
can result in data corruption.

Required operating system patches:

  (Solaris 9 SPARC)
     122300-11  (or greater)
        dependent patches:
        112233-12
        117171-17
        118558-39


To enable VxFS VMODSORT functionality, the following linemust be added
to the /etc/system file after the vxfs forceload:

        set vxfs:vx_vmodsort=1  * enable vxfs vmodsort

To disable VxFS VMODSORT functionality, the following line must be added
to the /etc/system file after the vxfs forceload:

        set vxfs:vx_vmodsort=0  * disable vxfs vmodsort


You need to use the shutdown command to reboot the system after patch
installation or de-installation:

     shutdown -g0 -y -i6
