The IBM ce downloaded a dump of data from the tape drive and send that on to the higher level support folks. They asked to update the firmware, which was just release. This help us greatly. Our tape drives are installed in an IBM 3584 (aka TS3500) so the tape drive dump can be gathered either via the CE's laptop tools or via the IBM library web interface. If you are using IBM's drivers, you should be able to download the drive dump via a utility supplied with the driver code. In our case this was not an option as the tape drives were attached to an netapp box. len -----Original Message----- From: ADSM: Dist Stor Manager [mailto:ads...@vm.marist.edu] On Behalf Of Richard Sims Sent: Tuesday, July 21, 2009 1:50 PM To: ADSM-L@VM.MARIST.EDU Subject: Re: [ADSM-L] Errno = 23, 1167 and stuck tapes Henrik - I don't have a direct answer for you; but my suspicion is that drive microcode is involved, perhaps in conjunction with cartridge vs. drive characteristics. The IBM readme document S1003097 for LTO4 shows a very large number of problems that have had to be corrected, suggestive of more, ongoing. The stuck tape situation may suggest a problem managing the mechanics and/or timing of drive operations. Given the mechanical malfunction which results, I'd have your CE attend to the next event, to examine the conditions logged in the drive's memory, to try to uncover the cause. The inability of an OS command to effect tape dismount indicates a serious problem. If the CE can't be gotten in time during the next event, see if you can have the operator get at the drive to record any error codes on its panel. Make sure the CE pores over the sense bytes you're getting from the drive.
