It is a setmode problem that resulted from an incompatibility between the atape driver and firmware. I assumed it was the drive firmware, but now I'm thinking it might have something to do with the library. It apparently only happens in a Quantum i6000 with IBM LTO5 drives. IBM says that it is a quantum problem, but quantum says it's IBM that provides them with the firmware in the first place.
Here is an output from the trace: 16:35:38.737 [131][psntpop.c][2871][DetermineResult]:Error performing SETMODE operation on drive WB_58 (/dev/rmt58); errno = 22 16:35:38.738 [131][psntpop.c][2931][DetermineResult]:Drive WB_58 (/dev/rmt58): sense=70.00.05.00.00.00.00.58.00.00.00.00.1A.00.30.00.10.41.80.0A.00.01. 54.31.35.32.33.31.4C.00.00.00.07.BC.26.00.00.00.00.26.80.55.30.4C.34.00. 00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00. 00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.45.50.35.34.52.46.31.4A. 52.31. 16:35:38.738 [131][output.c][6404][PutConsoleMsg]:ANR8302E I/O error on drive WB_58 (/dev/rmt58) with volume (OP=SETMODE, Error Number=22, CC=0, rc = 1, KEY=05, ASC=1A, ASCQ=00,~SENSE=70.00.05.00.00.00.00.58.00.00.00.00.1A.00.30.00.10.41.80. 0A.00.01.54.31.35.32.33.31.4C.00.00.00.07.BC.26.00.00.00.00.26.80.55.30. 4C.34.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00. 00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.00.45.50.35.34.52. 46.31.4A.52.31,~Description=An undetermined error has occurred). Refer to Appendix C in the 'Messages' manual for recommended action.~ I tried every atape version going backwards from the current 12.5.2 down, and 12.3.7.0 is the newest version that does not have this bug. I also tried every combination of drive firmware with each of these versions going back to Jan 2011. All had this problem after mounting a tape. 12.3.7.0 didn't work for me, because there was a separate encryption-related bug that was fixed with in 12.3.9! I finally downgraded to 12.3.2.0 and everything is working now. This is only a temporary environment so it won't affect me in the long-run.

Rgrds, Yudi -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[email protected]] On Behalf Of Shawn Drew Sent: Wednesday, 29 August, 2012 1:24 AM To: [email protected] Subject: [ADSM-L] AIX Atape request Greetings all, I ran into a bug which necessitates downgrading my Atape version. The only older version I have is 12.3.7.0, which is subject to another bug that is also affecting me. I need to get an Atape version between 12.3.9 and 12.4.8.0 IBM fix central does not have it and IBM support tells me Quantum will have it since it is the result of their incompatibility or something. Quantum only links to IBM. Google is not helping either. Does someone have their own little archive history of Atape? If so, please send me a copy or send me a link. I'm shocked that this stuff is not available "out-there" After this, I will definitely be maintaining my own archive.
