3719.0. "TLZ7L SHOWING MEDIUM FORMAT CORRUPTED" by WARFUT::MELLING () Fri Apr 11 1997 01:08

    
    	Hello,
    
    	I have a customer who has a TLZ7L-VA,in doing a vdump to the device 
    	no errors are shown,however it has been found that some tapes
    	show ADVFS I/O ERROR on vrestore.
    
    	The errorlog shows ASC/ASCQ of 3100 - MEDIUM FORMAT CORRUPTED.
    
    	I notice there have been a couple of similar entries for this
    	problem,2334,3205 and 3355.
    
    	The complete unit has been replaced to no avail.
    
    	The customer is running DEC-UNIX V3.2C on a DEC3000-800,the 
    	tape unit being installed in a BA350 connected to a PMAZ
    
    	I would be grateful for any help with the above.
    
    
    regards
    tony melling

	PMAZ, PMAZB or PMAZC?  If the single channel version, do
	a title search in the DIGITAL_UNIX conference and the archived
	conference that preceeded it to see what problems there were
	with the original PMAZ module on Alpha systems.  A low
	numbered note of the DIGITAL_UNIX conference should have the
	name and location of the preceeding conference.
