If you happen to be running any Atlas II drives with a frimware level below LYK8, you'd be well advised to upgrade your firmware. We saw some really nasty behavior on one of our machines here where, after a QUEUE FULL condition, the drive would simply never reconnect for any pending transactions. In CAM, the recovery code was able to bring the drive back to life by issuing a BUS DEVICE RESET, but I don't know that the older aic7xxx and NCR drivers would fair as well. After upgrading to LYK8 (from LXY4), this particular QUEUE FULL issue was resolved. Supposedly LYK8 was released specificly to deal with QUEUE FULL problems. The drive will still return QUEUE FULL for temporary write cache full conditions, but at least now it doesn't occasionally lose it's brain after doing so.
