terminated ioc 804b scsi 0 state c xfer 0

[Scott Long]

Hi Dan,

Can you share the entire console log for the uptime?  What you’ve pasted is missing the initial messages of the problem.  the “terminated ioc” messages are likely because the driver has decided to reset the drive and terminate all outstanding I/O to it.  In other words, they’re red herrings.  The reason for the driver deciding to do the reset is likely earlier in the log.

Thanks,
Scott
