Issue Description: 

Multiple problems have been reported regarding the DLT7000 tape 
drives in the above mentioned configurations.  These tape drives
may be susceptible to multiple problems, none of which can be
clearly defined since the failures appear to be different in each 
instance depending upon the drive's firmware revision and the  
configuration of the tape drive (library).

However, most of the reported problems in reference to the DLT7000 
failures stem from the current firmware rev. of the DLT7000 tape 
drive which does not allow the normal "Buckling Process" of the 
Take-Up Leader and Cartridge Leader to align properly and insure
alignment of the Take-Up Leader and Cartridge Leader.

A new DLT firmware version has been released that will correct many   
of the various failure conditions.

Implementation: 

---
  	|   |  	MANDATORY (Fully Pro-Active)
	 ---    

         ---
  	| X | 	CONTROLLED PRO-ACTIVE (per Sun Geo Plan) 
	 ---   
			
         ---
  	|   | 	UPON FAILURE
	 ---

Corrective Action: 

In order to avoid or correct problems associated with DLT7000 unit 
failures associated with Take-Up Leader and Cartridge Leader align- 
ment, the following recommendation has been issued:
				 
The recently released DLT V72 firmware will address and resolve the 
Take-Up Leader and Cartridge Leader alignment problem and will allow
for reliable engagement of the Normal Buckling Process.

V72 DLT firmware can be obtained by installing:

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.
