L700 hand fails to load SDLT - How to calibrate it

[Mario2]

Hi,

I have a problem with two L700e libraries. They both have a combination of LTO and SDLT drives. The problem is with the SDLT drives. The hand does not put the SDLT tape far enough for the drive to accept it. The hand pushes it three times in but not far enough; the tape keeps coming out pushed by the spring in the drive. After three non successful tries the drive is stuck – the tape is not loaded but it stays in the front part of the drive. Sometimes the hand pushes the tape far enough and then the drive accepts it and then it works fine.

The drives are seated OK in the drive tower.
The tapes are normally loaded in the LTO drives in the library because LTO drives have the loading mechanism.

Is there a way to set the hand to push the tape further into the drive?

Thanks a lot!

Mario

Hi,

I contacted StorageTek, and after going through all the mcode upgrades (not that any of them was helpful) the problem was fixed by replacing the hand assembly, since there was no way to calibrate the "slide the tape in" movement.

Usually , removing the exceesive tension on the toothed belt on the hand fixes the problem. The hand looses too much effort overcoming its own mechanical problems when the belt is too tight. Do not blame STK, the basic problem is the mount resistance of the drive itself, the drive was designed long after the L700 was.......! But not as well!!
