3679.0. "select density on TZ887" by ONOIS1::CAVAILHE () Thu Feb 27 1997 13:59

    Hello,
    
    
            A customer has bought an upgrade from Tz877 to Tz887.
    
            This drive is connected to KZPAA via 2 DWZZA.
    
            With Tz877,the customer used the utility SET_TZDENSITY.EXE to
    	    select the density in a batch procedure.
    
            At my knowledge,this utility has not been upgraded for Tz887.I
    	    know this utility is integrated in the driver in AOVMS V7.2.
    	    A french collegue has relinked the driver in AOVMS V7.1,but the
    	    customer can't upgraded in AOVMS V7.1,he is obliged to keep in
    	    AOVMS V6.2.
    
            Like on the customer site,there is an HSZ40,I propose to
    	    connect the Tz887 with 2 DWZZA on the HSZ40.
    
            - First the HSZ40 must be in V3.0Z-2.
            - Secondly,the customer want to select the density TK85,TK87,
    	      TK88 and compression mode in a batch procedure.
    	    My question is:
    		 Can we do via a script command like set host/scsi T0
                 and which are the good commands to select the
   		 densities?
    
            - Thirdly,can we select a random slot via a script command
    	      (passthrough container) or can we used MRU V1.1 ?.
    
            By advance,thank-you very much for a quickly response.
    
            Best regards.
    
            Olivier Cavailhe,CSC_France.

	As nobody has answered this yet maybe this will help. The setting of the density can be done by using HSDSA and HSZTERM. You can write a script that can then use the SET UNIT DEFAULT_FORMAT=xxxx on the HSZ40. I would also thing that MLU would be the best way of controlling the slot selection as it is a supported product. Cheers Keith

	Are you sure MLU is supported? The MRU team got an IPMT case on it recently because nobody else would take responsibility for it. WE certainly don't support it.
3679.3	Use 'R' not 'L'..	SUBSYS::TRAN	Straight <Left> Hitter..	`Wed Mar 12 1997 21:30`	5
	DON'T use MLU... This utility has never been officially supported and now there is noone maintains it.. Use MRU as Alan mentioned. T.

	Uh.... But we don't support density selection... MRU only controls the media changer, not the drives it has access to. The right thing to do is to have VMS recognize that there is more to tape drive density than being a 9 track drive or one with compression and one without.
3679.5		LEFTY::CWILLIAMS	CD or not CD, that's the question	`Thu Mar 13 1997 15:32`	10
	Which it does, in 7.2, for direct connect drives.... Don't expect this to be ported back to earlier versions. There are no plans to do so. It was a long, contentious battle just to get this far with density select. Chris

	Sorry for the issue I caused but .1 was a typo when I said MLU. I meant MRU but my old mate Micky's DEC ghost loomed large again. Sorry it took so long to come back but I have been off for over a week; treading the boards. Keith
