>Release: FreeBSD 4-STABLE i386
>Organization:
Private FreeBSD site - The Netherlands
>Environment:
FreeBSD-stable as of jul 27, 2001. (Old & weary) PTI ISP-2100-based
FCAL adapter.
>Description:
Forcing LIPs on the FCAL will after some time result in the
FCAL disk being dropped (invalidating pack). This will take
quite some clobbering of the AL though. And is supposedly
also dependent on the adapter / firmware in use.

>How-To-Repeat:
Inject LIPs during heavy disk I/O every 180 seconds did this.
My heavy I/O was a buildworld with /usr/src and /usr/obj each
on their own FC disk, both on the same loop.
>Fix:
mjacob has sysctl changes sitting in the pipeline to allow
retry tuning for the da(4) driver. Adding delay hysteresis
(Matt's words) in the isp driver is also called for.
