TL892 on a MDR connected to OpenVMS Alpha
I use OpenVMS and the MRU robot is able to see the drives and slots, but it does not seem to be able to tell me about itself. I.e.,
$ Robot Show Robot
always comes back blank. I can move tapes around smoothly. But, I am also getting failures when I try to INIT the tape. I don't know if this is related or not, yet.
Previously, when the TL892 was directly attached via SCSI, I had to load a driver at boot time in order to reference the robot. Something like this:
MCR SysMan IO Connect GKF0 /Driver = Sys$GKDriver /NoAdapter
but since I don't do anything like this for the MSL5000 and the TL892 robot already seems available, I am not doing anything with the $2$GGA2: device that is the TL892 robot.
I thought this library was qualified with an MDR on OpenVMS and it would be easy to setup and use. Is this correct?
Does anyone have any suggestions?

Re: TL892 on a MDR connected to OpenVMS Alpha
I am using MRU v1.8.
I have found that I can not get the MDR to work with the TL892 library. Maybe I was incorrect in assuming it would work. The parity errors I was getting on tape INITs were consistent across nodes in the cluster and multiple tapes in the library. It does not seem to be a problem on the library, drive or tape.
I then reattached to the SCSI card on one of the AlphaServer nodes and the backup job is humming along smoothly...
As for the "blank response from MRU" problem I was reporting, I think that I might have had a syntax error. The command I was using was actually:
$ Robot Show Robot $2$GGA1: Robot
^^^^^
that last "Robot" parameter is not right, it shouldn't be there and MRU seems to not report a problem, it just returns a blank.
If I had wanted to see "Slots" or "Drive" status, you replace the last parameter with them. That is where I went wrong, I incorrectly generalized... :)
I am starting to recall some old docs that mentioned that MRU was picky about the name of the device you use for the robot. E.g.,

Re: TL892 on a MDR connected to OpenVMS Alpha
Does that help? To me that is Single ended, non-Diff SCSI.

Re: TL892 on a MDR connected to OpenVMS Alpha
NOTE: I now see that the TL891DLX is supposed to be using a KZPCA-AA (UltraWide SCSI II or Ultra2 LVD) controller.
Wow! OK, so it should not even work with the KZPBA I am using... Opps. But from some specs I see, the KZPCA is a LVD system. The spec sheet I have on the TL891DLX lists: LVD, 68HD.

Re: TL892 on a MDR connected to OpenVMS Alpha
the "KZPBA" is available in 2(3) different versions:
SE: KZPBA-CA
HVD: KZPBA-CB (EOL) + KZPBA-CC
