1847674Scael.Sy "tape te0 at tm0 drive 0"
1947674Scael.Sh DESCRIPTION
2047674ScaelThe
2147674Scael.Tn TM-11 Ns / Tn TE-10
2247674Scaelcombination provides a standard tape drive
2320683Smckusickinterface as described in
2447674Scael.Xr mtio 4 .
2547674ScaelHardware implementing this on the
2647674Scael.Tn VAX
2747674Scaelis typified by the Emulex
2847674Scael.Tn TC-11
2920683Smckusickcontroller operating with a Kennedy model 9300 tape transport,
3047674Scaelproviding 800 and 1600
3147674Scael.Tn BPI operation at 125
3247674Scael.Tn IPS .
3347674Scael.Sh DIAGNOSTICS
3447674Scael.Bl -diag
3547674Scael.It te%d: no write ring.
3647674ScaelAn 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.
3947674Scael.Pp
4047674Scael.It te%d: not online.
4147674ScaelAn 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.
4447674Scael.Pp
4547674Scael.It te%d: can't change density in mid-tape.
4647674ScaelAn 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.
5047674Scael.Pp
5147674Scael.It te%d: hard error bn%d er=%b.
5247674ScaelA tape error occurred
5347674Scaelat block
5447674Scael.Em bn ;
5547674Scaelthe 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.
5947674Scael.Pp
6047674Scael.It te%d: lost interrupt.
6147674ScaelA 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.
