No change

Cause

From Sept 8 to Sept 29, we got 3 event that the robot go
Inop after a fetch that involved drive 0,1,1,9.

3 different media was involved in the inop
SUN077L4,SUN003L4 and SUN042L4.

All above logs indicated error detected area is 0,1,1,9 and positioned
5050 mils = 12.827cm from the top.

You may decode the mils to cm using the following website.

http://www.convertunits.com/from/mils/to/cm
4782 mils is 12.146cm
5050 mils is 12.827cm

This problem was cause by a bad drive in 0,1,1,9. The cartridge in this tape drive was ejected to far out
from the tape drive and obstruct the robot from moving down. (See attachment SL500-Inop.jpeg)

Note : The picture was taken after we move the tape drive from 0,1,1,9 to 0,2,2,9 to confirm the drive issue.

Solution

Replace drive in 0,1,1,9 solved the problem.
