sccli> sh ch
Ch  Type    Media   Speed   Width  PID / SID
--------------------------------------------
0  Drive   SCSI    80M     Wide     6 / 7
1  Host    SCSI    80M     Wide     0 / 1
2  Drive   SCSI    ASYNC   Narrow   6 / 7
3  Host    SCSI    ASYNC   Narrow   1 / 0
6  Drive   Unknown ASYNC   Narrow  N/A / N/A
7  Host    LAN     N/A     Serial  N/A / N/A

Resolution
In this case it was found the, there is no lun '0' configured. Lun 0 is a SCSI requirement and must exist for sd to work properly.

See Document ID:   <Document: 1017707.1>
Title:     Logical Unit Number(LUN) 0 , A SCSI Requirement
Once lun 0 is mapped, the channel changes to "80M/Wide" or appropriate setting. Hence we must map a lun 0 for proper operation of the 3310. This needs to be done on all host channels.
