Description:
We have a F820 with a lvd scsi card and a Overland Data LXS mini library express (1 dlt7000 and 15 slots) This is directly attached and controlled via ndmp and Veritas NetBackup 3.4.1
We were getting the following errors:
Sun Dec 1 12:30:18 EST [isp_timeout:warning]: 1.4(0x015e8ca4, 0x00): command timeout, quiescing bus to allow outstanding I/O to complete. Sun Dec 1 12:30:24 EST [isp_timeout:warning]: Resetting SCSI adapter 1 (ha #0) Sun Dec 1 12:30:25 EST [isp_timeout:warning]: Resetting SCSI bus 1 (ha #0) to clear outstanding I/O.
Solution: The problem was due to the qlogic single channel lvd scsi controller. This was the third one of these I had had in the system.
We found this out by doing an upgrade to 6.3.1 and having critical system problems. When I found a dual channel card and put that in, things worked fine and we have not had any errors since.
Our sales rep is sending us a dual channel to replace this single channel card, so they are taking care of us in that respect. Lost LOTS of time during this diagnosis since the card partially worked and we were able to do backups, but would have to sometimes reboot the filer to reset the jukebox.
We are getting a new STK L180 and will have SDLT320 tape drives to backup most of our filers (once we upgrade to 6.3.1 and Veritas 4.5).
Thanks to all who repsonded MBall@DATALINK.com Mikko Peltola [mikkotp@ssh.com] Sorry, but I lost the other emails, there were many other people who offered great advice.

right, one of the last qlogic cause problems with overland connected on (its a netapp known bug) i hope (i guess so) the dual qlogic card is supported by your filer. i know overland had develloped an experimental firmware patch to solve the problem. if you gonna get sdlt320 there is no need to dig further this problem. bubye
