AFAIU, the scsi_eh (error handler) already has proper code for exactly this purpose, but the code is inactive. Any driver (SCSI low-level driver or SCSI command set driver) can activate it by setting scsi_device->allow_restart = 1.
Brian King posted a patch which lets you enable that flag at runtime: "scsi: Add allow_restart sysfs class attribute", 2006-06-27 http://marc.theaimsgroup.com/?l=linux-scsi&m=115142503103468
The patch is in Linus' tree now. http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=history;f=drivers/scsi/sd.c -- Stefan Richter -=====-=-==- -=== ===== http://arcgraph.de/sr/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
