>Organization:
Private FreeBSD site - The Netherlands
>Environment:
-current as of Jul 23, 2001. PTI isp2100 based FC HBA.
Any x86 or axp box.
>Description:
Powering down FC disk cab results in LIP, noted by the isp driver.
This is OK. Running for example camcontrol rescan on the FC
loop/bus results in camcontrol hanging in 'cbwait' forever.
The I/O request obviously never times out.
>How-To-Repeat:
See description
>Fix:
Some timeout mechanism needs to be implemented so that a dead FCAL
can be detected and attached FC/SCSI devices can be declared 'gone'
properly.
