hi could anyone tell me the parameter to make CAM never timeout a transaction ? i need it to get rid of a problem with a dpt raid controller: Aug 4 13:16:13 newtrinity /kernel: (da0:dpt0:0:0:0): CCB 0xc83fd07c - timed out Aug 4 13:16:13 newtrinity /kernel: (da0:dpt0:0:0:0): CCB 0xc83fd07c - timed out CCB already completed simon shapiro who did the freebsd support for dpt controllers told me to first check if the array has a lost disk which normally causes this problem but it hasn't he told me further this is a classic problem if the dpt firmware takes too long in the opinion of the cam abstraction layer to complete a transaction and then the dpt completes a "non-existing" transaction a while later i already wrote an email to justin gibbs to tell me the parameter but he unfortunately didn't reply i had a look to the cam sources but i didn't see something concerning disabling the timeout for transaction thanks marius To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the messagehelp
