Re: mt rewoffl doesn't work

Hi Michael.
Sorry, but no ideas.
Just one thing.
In the parameter list for mt there is no rewoffl.
You either user rewind to leave the tape active and mounted in the drive or you use offl to set the drive offline ( which also includes the rewind ). And pls give it some time to work. It is a tape, which means, that the mechanical parts work very slow compared to other devices.
Hope i could help.
Regards

Re: mt rewoffl doesn't work

Hi Alex,

Tru64 has also rewoffl, although it seems to do the same as offl. The tape has time enough to unload but still the light is in use, mt status and ltt says, no tape.

strange, right?

thanks,

Michael

ps. Sie arbeiten nicht zufaellig in Frankfurt?

Re: mt rewoffl doesn't work

Hi Michael, the rewoffl was an amalgamation of rewind and offline and the only version of unix I have seen this working on is the late ICL's version DRS-NX. They had several other unique commands in their version which never seem to have surfaced anywhere else

Hi Malvin,

this has been working on many alphas and for many years nicely and only now I see this behaviour.

thanks,

Re: mt rewoffl doesn't work

Hi everybody,

finally the reason for the problem came out, after they began exchanging drives.
The new firmware V86 has a new feature. After 10 minutes of offlining a tape it goes into power saving mode and locks the tape again.

It's not a bug, it's a feature. Maybe HP should read their own documentation and communicate it.

thanks for trying,

Michael
