Hi All

In the recent commits in SCST SVN repository I added to SCST ability to
automatically notify initiators about the following two types of events:

1. Devices addition or removal (REPORTED LUNS DATA CHANGED)

2. If any device changed its size (CAPACITY DATA CHANGED)

Both types of notifications are supported: Asynchronous Events
Notifications (AEN) and Unit Attentions. If a target driver supports
AENs, they will be used, otherwise, Unit Attentions will be used.

At the moment in Linux only open-iscsi partially understands those
events. It can see added devices. But it doesn't process devices removal
or size changed events.

I'm going to make development freeze of SCST 1.0.1 tomorrow. Then after
few weeks of testing 1.0.1 is going to be released.

SCST is an alternative implementation of SCSI target subsystem for
Linux. You can find more information about it on its home page
http://scst.sourceforge.net
