Yes Tom you are correct. Thank you!! I am comparing two log files, fairly large ~2000 lines, but I only show little here. What could be different but never should be is the backing device. I should always have 2 twcsapxrqdb1_x1 in each log file but sometimes the OS puts them where it wants to. The problem with my previous code was when I added a new LUN to the VIOS, it would assign where the last vtscsi ID gap existed. Here is a visual of what it currently does using grep -p. Error warning from Test::More. got archive_d1f but expected archive_r1a.
