Install and Uninstall Instructions:
-----------------------------------
1.Installing VxFS 4.1 MP2RP8 patch:

a)If you install this patch on a CVM cluster, install it one
 system at a time so that all the nodes are not brought down
 simultaneously.

c)To verify the VERITAS file system level, enter:
 
     # swlist -l product | egrep -i "VRTSvxfs"
 
  VRTSvxfs     4.1        VERITAS File System  
  VRTSfsman    4.1        VERITAS File System Manuals

d)All prerequisite/corequisite patches have to be installed.The Kernel patch 
  requires a system reboot for both installation and removal.
 
e)To install the patch, enter the following command:

1.Special Installation Instruction: This patch requires 
the JFS fsck(1M) binary to be present at the
standard location (/sbin/fs/vxfs/fsck). The swverify(1M) command can be
used to verify the integrity of the JFS.VXFS-BASE-RUN fileset that
contains the fsck(1M) binary.
