When I create a new iSCSI volume, I get..

"These changes require resetting iSCSI connections.

WARNING! RESETTING ISCSI CONNECTIONS WILL CAUSE A SHORT OUTAGE FOR ALL ISCSI CONNECTIONS. SOME APPLICATIONS WILL HAVE SERIOUS PROBLEMS WITH ISCSI RESETS!

Press OK to reset iSCSI connections or CANCEL to abort,"

if you click cancel, no volume is created. If you click ok, all iscsi sessions are reset, possibly corrupting a file system.

So does this mean that everytime I want to create a new iscsi volume, I have to stop all application and server access to the SAN?
