Checking Solaris iScsi Performance with Dtrace

I've just discovered David Weibel's Blog and he has a couple of interesting posts regarding using dtrace(1M) to check performance issues with iScsi on Solaris.

• iSCSI Kernel Visibilty


• iSCSI device reporting lots of iSCSI sessions logging in and out


• And David show a way to disable MPxIO for the Solaris iSCSI initiator here.

David worked on the Solaris iScsi initiator code when he was at Sun Microsystems, Inc.
