MS ISCSI Initiator and Dynamic Disks

What the hell!!! Why is an iscsi lun not persistent...? It took me half a day to find out why some iscsi luns disappear after a reboot.

Dynamic disks on an iSCSI session are not supported. For best results it is recommended that basic disks be used with iSCSI. Basic Disks can be expanded in the same way that Dynamic Disks can be expanded. Please see KB325590 at http://support.microsoft.com/default.aspx?scid=kb;[LN];325590 for more information on extending a data volume on a basic disk. If you do attempt to setup a dynamic disk on an iSCSI volume,after logging into the target you may have to manually go into the disk manager and reactivate the disk. To do this, right click on the disk and select the Reactivate Disk menu item. Please see the iSCSI users guide for more information.
