Hi, I was just looking at the manpage for scsi (8) and was particularly intrigued by the -z option which claims to be able to freeze the scsi bus for an audible "beep" delimited (with the -v option) specified period of time provided you have compiled your kernel with the "SCSI_FREEZE" option. The manpage goes on to state that this kernel code is not committed yet and indeed a grep of the kernel source for -current for the string "SCSI_FREEZE" comes up empty-handed. I presume that an appropriately contrived sequence of scsi -z and scsi -p commands could be used to perform hot-swapping of scsi devices -- something I would dearly love to be able to do. Does this actually work yet and how should I specify any required kernel options? Thanks for your help, Tom
