1840.0. "Should an AlphaStation 600 be able to recognize an RZ56 ?" by PTHRED::VIVENEY (Bob Viveney) Tue Feb 04 1997 13:45

Hi
	I have a AlphaStation 600 5/266. Firmware rev is 6.0.
	I used the backpanel scsi connector to connect an expansion
	box with 2 RZ56 disks followed by a DAT tape drive. (50 pin)

	The system does not seem to recognize the 2 RZ56 disks. It does
	see the tape. It does not appear to be a conflict in scsi ids.
	
	Using 'show device' at the console level verifies that the 2
	RZ28s internal (scsi 0 & 1), cd drive (scsi 5) and tape drive
	(scsi 3) are seen. There is a terminator in place.

	If I try to boot Unix with the power on at the expansion box, it 
	repeatedly fails. Turning power off allows the boot to succeed.
										
	Then trying to mount the RZ56 disk will immediately crash the
	system.

	The disks are formatted for UFS and were used this way with an Avanti.

	Should this work with an Alcor?

	Thanks,
	Bob

	This seems to a repeat (mostly of topic 1748) which has no replies. Note that RZ5? are SCSI I devices and it looks like ISP firmware doesn't like them.
1840.2	Get Field Service To Check Config	XDELTA::HOFFMAN	Steve, OpenVMS Engineering	`Wed Feb 05 1997 11:24`	3
	The poster already received offline mail from various folks -- this looks like a hardware or SCSI-connection-related problem.
1840.3	KZPAA-AA adapter is one solution.	BASEX::EISENBRAUN	John Eisenbraun	`Wed Feb 05 1997 12:23`	5
	We've been using a borrowed KZPAA-AA (PCI TO SCSI HOST BUS ADAPTER) to connect our RZ56 and RZ57 drives. It seems to work without any problems on OpenVMS V6.2 and Digital UNIX (V3.2 and V4.0). We couldn't get the internal SCSI controller to work.
1840.4	RZ55/RZ56 can't handle narror/wide negotiation	WRKSYS::BIELAWSKI		`Thu Feb 06 1997 12:52`	4
	The RZ55/RZ56 disks do not handle narrow-wide negotiation properly. See note 681. Connie
