    Found the Terminator pack on the ST277N, it's under the drive, 3 yellow
    packs, that you can remove. ;-) Still search for the ID switch.

    look for a group of three jumpers. I don't know anything about your 
    drive but this seems to be standard.

5020.3ST277N jumpers setting ?TRUCKS::BUSSINK_EIt's Nothing PersonalFri Sep 06 1991 07:4910
    There is a set of four jumper, near the scsi bus.
    
    +-----------------------------+	
    |power    Scsi-bus	     :I:: |
    |				  |	The second from the Scsi-bus is set,
    |				  |	the rest are empty. There is no text
    |			          |	written on the board or drive.

5020.4did you try thisSALEM::LEIMBERGERFri Sep 06 1991 09:064
    Your controler should see the drive, and tell you the ID. If not
    try moving the jumper over one more from the scsi bus. if these are
    the id jumpers this should give you a "safe" id. ie 2,or 4
    
5020.5DH0 mounted twice �TRUCKS::BUSSINK_EDon't Ask, I Didn'tTue Sep 17 1991 06:1927
    OK last question before I leave DEC.  	:-( sniff
    
    	OK got the second HD (ST277N) working on my IVS Trumpcard. It boots
    	with the other disk. Here is an copy of the Info it gives me :
	
Mounted disks:
Unit      Size    Used    Free Full Errs   Status   Name
MSH:      720K      14    1426   0%   0  Read/Write Unnamed
VD0:      3.0M       5    6137   0%   0  Read/Write VD0
DF2:      Unreadable Disk
DF0:      No disk present
RAM:        2K       4       0 100%   0  Read/Write RAM
DH0:       46M   87579    5707  93%   0  Read/Write DH0
DH0:       62M   17898  107680  14%   0  Read/Write DH1

Volumes available:
Unnamed [Mounted]
VD0 [Mounted]
RAM [Mounted]
DH1 [Mounted]
DH0 [Mounted]
    
    		Why are there 2 DH0 mounted, also being the second one
    (DH1), if I check with a program like sysinfo 2.36, it's a description
    of the first Harddisk (DH0). Any explanation ?

5020.6Setup problems??!!!ARRODS::GOLDSTEINSteve G DTN: 847-5416/5455Tue Sep 17 1991 08:1412
    Hi Eric
    	   This problem might be in the way you set the drives up..
    
    	I don't have the IVS card BUT when using the Nexus or HardFrame 
    there was a mode to allow you to set up the Logical and Physical Names
    
    	Device		Logical name		Buffers		Boot
    	DH0		Nexus_000 		30		yes
    	DH1		Nexus_001		30		Mount
    
    	Regards
    	Steve G
5020.7BOMBE::MOOREAmiga: Where 'multimedia' REALLY beganTue Sep 17 1991 18:279
    Each hard disk partition appears as a device in AmigaDOS, and one of
    the things defined in the partition setup is the device name associated
    with that partition.  It would seem that you have the name "DH0"
    defined on both drives, probably because that's the default name
    offered by their partitioning software.
    
    I think the IVS card uses the Rigid Disk Block (RDB) standard, right?
    If so, you should be able to modify the partition name for DH1 without
    losing data.  (But be sure to make a backup just in case...)
