Issue Description: 

When patch 105463-05 (SEVM2.5 patch) is applied on an operational system, 
and the system is rebooted, some storage devices may appear to be missing
or longer listed.

This symptom may also be experienced when installing EVM2.6, upon execution 
of vxinstall, not all of the storage devices on the system will be available 
for EVM to use.

This may happen on systems that have a mixture of storage devices, although
there have been reports of systems with a single SPARCstorage Array attached,
experiencing loss of access to some of the disks after application of this 
patch.  

The device loss is due to a modification that had been made to the DMP driver 
binary file in this release of the patch.

Systems that have disabled DMP operation will not experience this problem.

Implementation: 

---
    	|   |  	MANDATORY (Fully Pro-Active)
  	 ---    
  	 
  
         ---
    	| X | 	CONTROLLED PRO-ACTIVE (per Sun Geo Plan) 
  	 --- 
  	 
  	   			
         ---
    	|   | 	REACTIVE (As Required)
  	 ---

Corrective Action: 

There are two recommended methods to resolve the problem with missing 
storage devices after the SEVM patch (105463-05) has been applied.
     
  1.  Backout the 105463-05 patch.
  
  2.  Disable DMP operations.  
  
PROACTIVE approach for those sites wishing to apply this patch, use 
of the following procedure will allow full functionality without the
system exhibiting device loss.
  
  1) Copy the /kernel/drv/vxdmp binary to another location on the system
  	# cp /kernel/drv/vxdmp /var/tmp/vxdmp
  
  2) Apply patch 105463-05.
  	# installpatch....
  	
  3) Move the binary copy back into place in the kernel/drv directory
  	# mv /var/tmp/vxdmp /kernel/drv/vxdmp
  	
  4) Shut down the system and reboot.

Comments: 

Veritas has provided a binary fix which will become patch 105463-06.
  This patch is scheduled for release in December 1998.

Implementation Footnote: 

________________________

i)   In case of MANDATORY FINs, Enterprise Services will attempt to contact   
     all affected customers to recommend implementation of the FIN. 
        

ii)  For CONTROLLED PROACTIVE FINs, Enterprise Services mission critical sup-   
     port teams will recommend implementation of the FIN (to their respective 
     accounts), at the convenience of the customer. 


iii) For REACTIVE FINs, Enterprise Services will implement the FIN as the need  
     arises.
