TL891 + Modular Data Router

Can anyone help me with TL891 + Modular Data Router?
We have a Proliant ML530 + Modular Data Router + TL891
it worked but, after a hardware problem (levers broked)
it no more has been recognized by windows. The W2k can
comunicate with Data Router and Media Changer but cannot
access the tape drives!! It only happens when fibre channel
connected, if scsi connected the library works fine.

Eduardo,

Open the web browser for your MDR and check if there still exists a mapping to the tape drive. If not, perform a new inventory and reboot the MDR once.

Hi Kurt, we have already remapped the MDR under an hyperterminal session:
- clearFcSCSIMap
- remapFcSCSI
but it do not fix the problem.

Re: TL891 + Modular Data Router

try torun the following command and see if the scsi devices are discovered by the MDR:

>showscsidevices

you should see something like this:
AMC>showscsidevices
Device# SCSI Bus# SCSI Target ID SCSI LUN Port# Slot# Type
0 0 0 0 0 0 0x0C
1 9 0 0 9 3 0x08
2 9 1 0 9 3 0x01
3 9 2 0 9 3 0x01
4 10 3 0 10 3 0x01
5 10 4 0 10 3 0x01

type 0x0C is the MDRcontroller
type 0x08 is the robot
type 0X01 is the drives

Tks, Marino.
The showscsidevices command returns all the devices connected (media changer + 2 DLT drives) but the DLTs continues not discovered by the W2k.
