Hello,
I alraedy posted this question to freebsd-scsi but didn't
get a response till now - maybe someone of you has an answer
can you help me with the message at the bottom?
Right now I'm running the GENERIC 4.2 STABLE kernel.
Does it mean the disk is too slow or faulty?
When I ran this disk on Linux (before switching to
FreeBSD) there were no messages like this.
The disk (da7) is placed in a concatenated vinum-plex.
When I launch vinum it tells me the drive is up (without
problems)
Attached is compete dmesg printout.
ahc1: <Adaptec 2940 SCSI adapter> port 0xe800-0xe8ff mem
0xea001000-0xea001fff irq 10 at device 10.0 on pci0
aic7870: Wide Channel A, SCSI Id=7, 16/255 SCBs

da7: <Quantum XP32150 81HB> Fixed Direct Access SCSI-2 device

da7: 2050MB (4199760 512 byte sectors: 255H 63S/T 261C)
...
This message appears in the kernel log after some hours running without
problems:
