In 2.5/2.6, things will change because of the generalized Linux support for dynamic I/O config changes, with automatic execution of device startup/cleanup scripts, etc. (If that's what you mean by "hotplug".... not sure what the official Linux name for this function is.) But I think you do not want automatic assignment of a drive that comes online (attached, in VM terms). That needs to wait until the drive is actually needed. The point is that assignment of a drive when it comes online or at driver load time prevents any kind of multi-host sharing. It's not a Linux problem, per se, but a driver issue. The real point of discussion is whether the mt, UTS or a combination approach is best. One of the advantages I see in the UTS approach is that the driver can prevent access to the standard label, just as the dasd drivers do for disks.
