equivalent of Linux dev loss timeout?

Linux SCSI initiator drivers have the ability to send transport events
(e.g. link up/down) to a module that handles reporting and removing
devices from the system. By setting a "dev loss timeout", users can
specify how long a device can be missing before it is removed from the
system.

As one example of how this is used, enthusiastic testers can run IO to
a device, yank out the cable between the initiator and the device for
less than dev loss timeout seconds, and then watch as the IO's resume
after the cable is reinserted.

Does anything like this exist in CAM or would it be up to each SIM to
implement this behavior?
