[Veritas-bu] LTO with HP/Fibre

Hi Rusty,

I believe the issues were:

1)  The drives claimed they were self terminated, while we had to manually
terminate them

2) I am not sure which one but, only one of the modes worked on the bridge, I
think it was indexed but not too sure...

I would check with HP on makenod and compression, I am not sure what we had done
with that...

Also you have to play around with the fragment size, data_buffers etc, to get
any kind of performance.

I hope this information helps.  All have  a great day.

Regards,

Yucel

P.S. latest I have heard was, HP did not recommend fibre attached HP LTO drives,
might want to double check...

I'd like more info on the tricks you did to resolve the I/O errors.
Thanks!
