Release:        VxFS 5.0
Fileset:        VRTSvxfs
Fileset Level:  5.0.1.30

Software patch for the VERITAS File System (VxFS) to install over the
VRTSvxfs fileset.

Patch Installation:

   If the currently installed VRTSvxfs is below 5.0.1.0 level, you
   must upgrade VRTSvxfs to 5.0.1.0 level before installing this patch.

   AIX maintenance levels and APARs can be downloaded from the
   IBM Web site:

       http://techsupport.services.ibm.com

   Install the VRTSvxfs.5.0.1.30-incr.bff patch if VRTSvxfs is
   already installed at fileset level 5.0.1.0 

    A system reboot is required after installing this patch.

   To apply the patch, first unmount all VxFS file systems,
   then enter these commands:

       # mount | grep vxfs
       # cd <patch_location>
       # installp -aXd VRTSvxfs.5.0.1.30-incr.bff VRTSvxfs
       # reboot

Additional Notes:

   If you need to remove the patch, first unmount all VxFS
   file systems, then enter these commands:

       # mount | grep vxfs
       # installp -r VRTSvxfs 5.0.1.30
       # reboot
