nothing is solved yet. i rebooted everything this morning to make sure the scsi bus was cleared and reset. then i decided to try the individual btape tests to see if i could isolate the issue. the fill test is running all day still running:
16:23:27 Flush block, write EOF Wrote blk_block=12325000, dev_blk_num=5000 VolBytes=795,110,335,488 rate=38313.0 KB/s Wrote blk_block=12330000, dev_blk_num=10000 VolBytes=795,432,895,488 rate=38313.8 KB/s i get the impression that the issue was with the read part of the btape test, i may upgrade the mpt drivers for the LSI controller when this finishes as well. right now they are version 3.x: # cat /proc/mpt/version mptlinux-3.04.02 Fusion MPT base driver Fusion MPT SPI host driver and version 4.00.13.04-1-rhel5.x86_64 is available. -- michael On Tue, Oct 30, 2007 at 10:20:02PM +0200, Michael Lewinger wrote: > Hi Michael, > > So - what was the issue ?
