If all four iSCSI ports of the DS3300 are used to connect to servers, every logical drive that is

mapped to the host will initially be seen 4 times before the MPP driver combines them and

shows only one disk to the user. This information can be found in the file /proc/scsi/scsi, which

shows SCSI devices that are detected by the Linux kernel. See Example 17-17. SCSI port 5,

6, 7, 8 are the iSCSI connections to the iSCSI ports of the DS3300. Both LUNs (0 and 1)

appear on each SCSI port as well as the Access LUN also called Universal Xport. SCSI port

9 represents the two logical drives configured on the DS3300 that are seen by the user as

physical disks.
