>Description:
I want to use a SAN volumn mapping to two ports of a fibre from the HBA card.
And I want to use gmultipath with it, but it failed.

And I notice that someone had the similar problem:
http://forum.nginx.org/read.php?23,113752

The information of the volumn in dmesg:
da1 at isp0 bus 0 scbus2 target 0 lun 0
da1: <HP MSA2012fc J200> Fixed Direct Access SCSI-5 device
da1: 400.000MB/s transfers
