Hello everybody,
Hopefully, somebody can help me out there...
Lately, I?hooked?a M2442AC (which is basically the M2442A with an extra buffer) to a
QT13-type coupler in a?microVAX, in order to save some tape contents to disk and CD-ROM.
Unfortunately, when?read a tape on VMS with the DIR-command,?I get the
following?console-output:
%DIRECT-E-OPENIN, error opening UVAX33$MUA0:[]*.*;* as input
-RMS-E-FND, ACP file or directory lookup failed
-SYSTEM-F-TAPEPOSLOST, magnetic tape position lost
VMSMUP050.A;1
?
Although there seems to be a problem, the name of the file can be read out. Copying
doesn't work, though. I get the same error.
?
Therefore, I launched the NVRAM-internal diagnostics of the Emulex-controller. The manual
of the controller points out the NVRAM-settings for some types of drives, but not for
drives made by Fujitsu :(
The diagnostic tests, which can be run out of the diagnostics menu, all fail (except for
"BOT/rewind"- and "host memory DMA"-tests) with the same error
description:
?
** ERROR ** Blank tape read
?
I can't find any furhter description to that error type. I tried to play this the
NVRAM settings for the type drive and made repetitive tests, but each time, I get the same
error.
Does anybody uses such a drive/controller combination and give me some help regarding the
settings ?
Here are the current ones, which are stored in the QT13 for my fujitsu-drive:
?
Drive type, 0=Start-Stop, 1=Streamer (0-1,def=1 dec) :
On the fly commands (Y/N,def=Y) :
Enable data busy timeout delay? (Y/N,def=Y) :
Remote density (Y/N,def=Y) :
CDC tape drive (Y/N,def=N) :
Use IDEN line to select remote density (Y/N,def=N) :
IDEN line true selects high density (Y/N,def=N) :
Adaptive DMA (Y/N,def=Y) :
Blank Tape Timeout value, in seconds (1-60,def=5 dec) :
Max retry count for tape errors (0-10,def=3 dec) :
uSec Delay between DMA bursts (4/8,def=4) :
Adaptive DMA threshold (1-7,def=4 dec) :
Tape Drive Speed thousands of bytes/second (0-65535,def=625 dec) :
Support? 800 BPI Density (Y/N,def=N) :
Support 1600 BPI Density (Y/N,def=Y) :
Support 6250 BPI Density (Y/N,def=Y) :
?
"def=" means that this is the currently stored value.
?
Any ideas what might be the problem here?
?
Thanks alot for any hints in advance !
?
Best regards,
Pierre
