Hi,
My HP machine is using as boot device a disk defined in the Storage (IBM V5000). The connection is done by fiber connected through fiber switch.
No lacal disks are installed.
I'm using redhat 6.6.
I've installed and configured multipath.
Everything seems to work properly, however, randomly, after having rebooted the machine, I could have the following errors:
Oct 6 13:07:36 sms01 kernel: device-mapper: multipath: version 1.6.0 loaded
Oct 6 13:07:36 sms01 kernel: device-mapper: multipath round-robin: version 1.0.0 loaded
Oct 6 13:07:36 sms01 kernel: device-mapper: table: 253:0: multipath: error getting device
Oct 6 13:07:36 sms01 kernel: device-mapper: table: 253:0: multipath: error getting device
This is the output of multipath -ll

While, the command multipath -d shows:
