Andy I have the same issue, AIX 5.3 TSM 5.4.1.0, TS3500, LTO2 but only on a single drive. I put this drive online and it works for a couple of hours then the ANR8963E. Some temp errors show in the AIX error log, but only for this drive. The drive tested ok but was replaced anyway. No errors on the san, none on the library itself.
The only complicating factor is that TSM Server runs as non-root so san discovery is not available. I've been running with the drive offline for a month now, since the afternoon it first happened and still have no clue as to where to go from here to debug it. All I know is if I put it back on line I get woken up sometime in the early hours - so its staying offline for now :) Steven Harris TSM Admin, Sydney Australia Andy Huebner <[EMAIL PROTECTED] ONLABS.COM> To Sent by: "ADSM: ADSM-L@VM.MARIST.EDU Dist Stor cc Manager" <[EMAIL PROTECTED] Subject .EDU> [ADSM-L] ANR8963E & ANR1791W 13/02/2008 02:57 AM Please respond to "ADSM: Dist Stor Manager" <[EMAIL PROTECTED] .EDU> We started seeing this error after we upgrade to 5.4.2.0 ANR8963E Unable to find path to match the serial number defined for drive XXXXXX in library IBM3494 This error causes the path to go off-line. We update the path with AUTODETECT=YES and it fixes the path every time. But the error will happen again and again... but to a random drive. IBM asked us to turn on SAN Discovery to resolve the error which has generated this error: ANR1791W HBAAPI wrapper library /usr/lib/libHBAAPI.a(shr_64.o) failed to load or is missing. We are running AIX 5.3 and the correct version of the API is loaded. This whole thing is starting to drive us nuts with paths dropping every day and with IBM not having a solution yet. Does anyone have a solution to these errors? We are stuck and IBM is working on it.
