Hi,
With 2.6.17.2, if a FC device is in use (mounted FS), a scan error is reported
when recovering after a 'long' link down period (>30s, 'no device timeout').
Then, devices aren't detected again (and oops are generated when reloading HBA
drivers, but this may be a side effect).
We have this issue with point to point configuration using:
- Emulex + DDN
- Emulex + NEC
- QLogic + DDN
- QLogic + NEC
In all cases, we got the message "Unexpected response from lun 0 while scanning,
scan aborted" in the scsi_report_lun_scan function (scsi_scan.c) and I'm
thinking there's something wrong when calling scsi_probe_and_add_lun.
We don't have such error if devices aren't used (not mounted) when link failure
occurs.
Do you know if such issue has already been encountered ?
May be an already existing patch ? (I look for scsi_probe_and_add_lun in the
mailling list but didn't find any revelant message)
Here are the extracts from syslog about these errors:

This is a known side effect of removing a fibre target which
has references. There is a crude workaround available. Essentially,
it modifies the fc transport to not delete the target when the
timer expires.
http://marc.theaimsgroup.com/?l=linux-scsi&m=115015423722568&w=2
Root cause is being investigated by various interested parties.
Be sure to read the entire thread. This patch is not going to be
accepted into the kernel.
