SPECIAL 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

ERR [1543]: 25004: Queue processing failed five times in a
row. Queue processing will be disabled and the CR will no longer accept new
backup data. Please contact support.
