I have an extensive background in SCSI and OS development, including 15 years of working with the Linux kernel. I would also like to have a discussion at LSF/MM 2015 about how we could better handle devices whose properties change after being probed. This includes: - READ CAPACITY data - ALUA state - EMC OWNED/UNOWNED state - NOT READY state Currently, when these properties change, we do not always handle it very well (e.g. multipath stops using a path if the capacity changes, even if it the only good path to the device...) -Ewan Milne
