On the MSA1000, I believe that you need to present the storage to the
right host and that's normally done by WWN (World Wide Name). It's been
a couple of years since I saw an MSA1000 being configured (for a Windows
server) but the concept should be the same as any other SAN controller.
The WWN you can get by looking at the switch (if the MSA1000 is
connected to a switch) or from the host. e.g.:
[ewilts@corpftp ewilts]$ grep adapter-node /proc/scsi/qla2300/?
/proc/scsi/qla2300/0:scsi-qla0-adapter-node=200000e08b191b91;
/proc/scsi/qla2300/1:scsi-qla1-adapter-node=200000e08b19a7a3;
