Hello, everyone! Here's what I got:
Server: pSeries 6M1 OS: AIX 4.3.3.10 Atape version: 8.3.6.0 ITSM: 5.1.6.4 Library: IBM 3494 w/8 3590H1A-FC drives SAN Switches: Cisco MDS 9216 fw:1.2(2A) fcs1 adapter is attached to SW-A. fcs2 is attached to SW-B. rmt8 is attached to SW-A (port 0 on 3590 drive) and SW-B (port 1 on 3590 drive). In AIX the drive is configured for alternate pathing and shows up as follows. rmt8 Available 7A-08-01-PRI IBM 3590 Tape Drive and Medium Changer(FCP) rmt81 Available 71-08-01-ALT IBM 3590 Tape Drive and Medium Changer(FCP) [BTW, rmt81 after doing rmdev -l rmt9 ; chdev -l rmt9 -a new_name=rmt81.] This all works fine. But to test the configuration I started a full DB backup and then did the following: 1) after the DB backup process started writing to the tape, I pulled out the fiber attached to port 0 of the drive. The DB backup stopped and failed. I reattached the fiber. 2) after the DB backup process started writing to the tape, I pulled out the fiber on fcs1. The DB backup paused and then after a few seconds continued and completed successfully. I reattached the fiber. So, I was wondering if I am missing something to make the first scenario not successful? Any insight would be appreciated. TIA Mahesh
