Hi Ed,
The persistent reservation is a SCSI-3 feature. I'ts useful in a
cluster environment, where multiple nodes are configured to access a
device while at the same time blocking access to other nodes.
To disable the iSCSI offload feature, disable the Broadcom iSCSI diver
(bnx2i), for example:
Ooops, I missed a citation:
We normally see these when the target has multiple controllers and one
of the controllers is in passive mode where it would normally be used to
fail over to, or when one controller is being upgraded or when some
management operation is being executed on a controller.

We've been wrestling with this for ... rather longer than I'd care to admit.
Host / initiator systems are a number of real and virtualized CentOS 5.5
boxes. Storage arrays / targets are Dell MD3220i storage arrays.
