I have a new dell md3600f ( 2 controller ) fiber channel storage, two
qlogic 2560 single port HBAs and two brocade 300 switches. FC cables
are redundant connected between switches and
storage controllers.
Â*
I have installed multipath-tools and configured my multipath.conf file.
I couldn't find and understandÂ* the "mpath_prio_rdac" file. There isn't
the file on the disk and repos.Â*
What / Where is the file?
The multipath software and failover mechanism are work fine. But I get
lot of failures at computer boot time and when after down/up the switch
port. These failures are shown asÂ* "Buffer I/O error on device sdc,
logical block" in kern.log but there is no problem on runtime and I can
access to the all disk volume on the storage.Â*
My system is debian/squeeze. How can I solve this problem?
