Ooops, I missed a citation:
"We normally see these when the target has multiple controllers and one

Hi,
In last summer, I have had same problems with Dell + CentOS +
multipath combination. For example I/O errors and stability problems
on the initiator machines. The initator machines are (in a Pacemaker
cluster):
- Dell R310
- Broadcom 5709 Gigabit Ethernet card (4-port)
- CentOS 5.4
- 2 Ethernet
