HBA Drive Parameter settings for tape

[Robert Skeffington]

I have been scouring the net; working with vendors and calling in favors from associates to help with the following:
Does anyone know what parameter settings need to be changed on an HBA for connectivity to a tape drive rather than a disk? In the past I had a great document that showed, for example: Queue Depth, Queue Target, TVOL, Class, etc. The drives work for the most part, but do drop off-line every once and a while, and I just wanted to make sure that the HBA is tweaked out for the tape world.
Any help would be greatly appreciated.

There is one parameter that can cause this behavior, and depending of your HBA vendor there is different way to set it
reseTPRLO=2 for emulex, and via the gui for Qlogic this setting avoid target reset to be sent to the tape causing the drive to reset and the backup to abort

Grazie molto! I will be sure to try this during my weekend upgrade to the servers.
