395.0. "NSR V4.3 for Windows NT does see devices on an HSZ controller." by COMICS::JUDD (Geoff Judd. UK TSC. Viables, Basingstoke) Fri Feb 07 1997 09:43

Hi,
  I have a customer who has an Alphaserver 1000 running Windows NT server 3.51
SP5. On this system are some local SCSI disk and tapes plus an HSZ controller
with some disks and a TZ88 tape drive. All these devices are accessible from NT
and the customer has another backup software package that can access the TZ88
tape drive. However the NSR software does see the TZ88 tape drive. When an
INQUIRE command is run from the DOS command none of the devices on the HSZ
controller are seen.

Has anyone successfully used an HSZ controller with NSR ? Is it supported ? If
it is does anyone have any ideas on what I need to do to configure it correctly ?

Thanks in advance,

Geoff Judd.

	395.0: "NSR V4.3 for Windows NT does see devices on an HSZ controller." ^^^^^^^^ >However the NSR software does see the TZ88 tape drive. ^^^^^^^^ Should we multiply by (-1)? We have not tested on an NT system with disks and tapes on an HSZ controller. Can you list what you seen under HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP and HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\Scsi My guess is that these devices are not listed under the Scsi entry and are therefore not seen. Thanks/mark

	Never mind, I found a HSZ in the NT group downstairs and had a look. There's nothing odd about the way the Registry represents the Scsi bus. We'll have to hook one up and take a look at how to support it. /m

	Mark, Thanks for your assistance. Do you have any idea of when you will be able to look into it further ? Also do you get the same symptoms as my customer reports ? Sorry about the missing 'not'. Geoff.

	I have now obtained an HSZ and I have found that the INQUIRE command without any arguments does not find any of HSZ devices however if the -c b.t.l argument is specified it can find the tape drive. It gives the tape drive device name and this can be used to configure the device in the graphical interface. Geoff Judd.

	Well that struck a bell. The device search code only looks for tapes and changers at LUN 0. If it finds a tape a LUN 0 it will check for a changer at LUN 1 (like the TZ887). Your base note does on say which LUNS the tapes for set to in the HSZ passthrough command. This is extra code in the search that I'm sure was added to speed it up on most systems since unless you use a controler like an HSZ tapes are never on a LUN other than zero. We we do here to make it easyier (normally on UNIX) is to keep LUN 0 and LUN 1 free of disks so the tapes will look 'normal'. If this is not pratical an enhancement request could be sent to Legato to either check all luns (up to 256 in SCSI 3) or have a switch that would for the check for all LUNS. I'm not sure if either option is a great idea but they are options.
395.6	Does this apply to the SWXCR also?	NNTPD::"[email protected]"	Karl Harris	`Tue Apr 29 1997 08:15`	14
	I have a customer who has similar symptoms using a TZ887 and a SWXCR. Does the LUN issue apply here? His tape drive is connected to LUN 2, with LUN 0 and LUN 1 being a shadow set. Thanks in advance for your reply. Karl Harris Technical Support Philadelphia, Pa. [Posted by WWW Notes gateway]

	Well even if the tape is found a LUN 2, where is the changer? It needs its own LUN defined as a passthrough device. Can the SWXCR support this? I don't know NT well enough to know if it would look for a tape at a LUN other than zero.
