The current code retries this case until it encounters a different ASC/ASCQ. Basically, it means your disk is just spinning up. > Any ideas as to what this is? > > Flaky scsi-disk? Something else? Together with the other SCSI complaints, i would first look for a misterminated (or mis-powered) SCSI bus. Make sure only the ends of the chain get terminators, and avoid having anything else than the SCSI controller feeding termination power. (It's in theory acceptable to have more than one source of term power, but in practice, it has proven to lead to occasional problems. Disk spin-downs belong to this problem category, from my experience.) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
