19*47674Scael.Sh DESCRIPTION
20*47674ScaelThe
21*47674Scael.Tn TM-11 Ns / Tn TE-10
22*47674Scaelcombination provides a standard tape drive
2320683Smckusickinterface as described in
24*47674Scael.Xr mtio 4 .
25*47674ScaelHardware implementing this on the
26*47674Scael.Tn VAX
27*47674Scaelis typified by the Emulex
28*47674Scael.Tn TC-11
2920683Smckusickcontroller operating with a Kennedy model 9300 tape transport,
30*47674Scaelproviding 800 and 1600
31*47674Scael.Tn BPI operation at 125
32*47674Scael.Tn IPS .
33*47674Scael.Sh DIAGNOSTICS
34*47674Scael.Bl -diag
35*47674Scael.It te%d: no write ring.
36*47674ScaelAn attempt was made to write on the tape drive
3720683Smckusickwhen no write ring was present; this message is written on the terminal of
3820683Smckusickthe user who tried to access the tape.
39*47674Scael.Pp
40*47674Scael.It te%d: not online.
41*47674ScaelAn attempt was made to access the tape while it
4220683Smckusickwas offline; this message is written on the terminal of the user
4320683Smckusickwho tried to access the tape.
44*47674Scael.Pp
45*47674Scael.It te%d: can't change density in mid-tape.
46*47674ScaelAn attempt was made to write
4720683Smckusickon a tape at a different density than is already recorded on the tape.
4820683SmckusickThis message is written on the terminal of the user who tried to switch
4920683Smckusickthe density.
50*47674Scael.Pp
51*47674Scael.It te%d: hard error bn%d er=%b.
52*47674ScaelA tape error occurred
53*47674Scaelat block
54*47674Scael.Em bn ;
55*47674Scaelthe tm error register is
5620683Smckusickprinted in octal with the bits symbolically decoded.  Any error is
5720683Smckusickfatal on non-raw tape; when possible the driver will have retried
5820683Smckusickthe operation which failed several times before reporting the error.
59*47674Scael.Pp
60*47674Scael.It te%d: lost interrupt.
61*47674ScaelA tape operation did not complete
6220683Smckusickwithin a reasonable time, most likely because the tape was taken
6320683Smckusickoff-line during rewind or lost vacuum.  The controller should, but does not,
6420683Smckusickgive an interrupt in these cases.  The device will be made available
6520683Smckusickagain after this message, but any current open reference to the device
6620683Smckusickwill return an error as the operation in progress aborts.
