Description
This article addresses how to identify Disk Drive IDs (CH:# ID:#) in a single-bus or split-bus (dual-bus) configuration in a StorEdge[TM] 3310 or 3320 SCSI Array. Identifying cabling schemes are also identified with connecting the JBODs (Just a Bunch of Disks).


Steps to Follow
This document illustrates how you identify and or correct Disk Drive IDs on a Sun StorEdge[TM] 33x0 SCSI Raid Array with attached JBODs

Disk Drive IDs on a 33x0 with a RAID controller (single-bus configuration):

 CH0-ID0		CH0-ID3		CH0-ID8		CH0-ID11
CH0-ID1		CH0-ID4		CH0-ID9		CH0-ID12
CH0-ID2		CH0-ID5		CH0-ID10	CH0-ID13

Disk Drive IDs on a 33x0 with a SCSI RAID controller (dual-bus configuration):

 CH2-ID0		CH2-ID3		CH0-ID0		CH0-ID3
CH2-ID1		CH2-ID4		CH0-ID1		CH0-ID4
CH2-ID2		CH2-ID5		CH0-ID2		CH0-ID5

See <Document: 1003147.1> for single-bus/dual-bus configurations

NOTE: ID 6 & ID7 are reserved for internal channels. Each drive channel can
have up to 16 IDs (0-15). The terms 'Dual-bus' and 'split-bus' are interchangeable.

Disk Drive IDs on JBOD connected to 33x0 RAID Array within a Single-bus
configuration.

The following cabling Scheme is needed:
A)Jumper cable on RAID array from SB-port (SINGL BUS CONF) to CH:0,
B)Jumper cable on JBOD from Upper-Right Port to Lower-Left Port,
C)Jumper cable from RAID array's CH:2 port to JBOD's Lower-Right Port

 CH2-ID0		CH2-ID3		CH2-ID8		CH2-ID11
CH2-ID1		CH2-ID4		CH2-ID9		CH2-ID12
CH2-ID2		CH2-ID5		CH2-ID10	CH2-ID13

To attach a second JBOD to a 33x0 SCSI array within a Single-bus
configuration, Host Channel ports 1 or 3 need to be configured
as a drive channel and then attached to the 2nd JBOD. Use the
following cabling scheme with Host Channel port 3 configured as
a drive channel:

A)Jumper cable on RAID array from SB-port (SINGL BUS CONF) to CH:0
B)Jumper cable on 1st JBOD from Upper-Right Port to Lower-Left Port
C)Jumper cable from RAID array's CH:2 port to JBOD's Lower-Right Port
D)Jumper cable on 1st JBOD from Upper-Right Port to Lower-Left Port
E)Jumper cable from RAID array's CH:3 port to JBOD's Lower-Right Port
NOTE:Host Channel port 1 is connected to a server

The following Disk IDs are seen...

33x0 SCSI array's disk IDs (w/ controller):

 CH0-ID0		 CH0-ID3   	CH0-ID8   	CH0-ID11
CH0-ID1	  	 CH0-ID4   	CH0-ID9  	CH0-ID12
CH0-ID2	  	 CH0-ID5   	CH0-ID10  	CH0-ID13

1st JBOD's disk IDs:

 CH2-ID0		CH2-ID3		CH2-ID8		CH2-ID11
CH2-ID1		CH2-ID4		CH2-ID9		CH2-ID12
CH2-ID2		CH2-ID5		CH2-ID10	CH2-ID13

2nd JBOD's disk IDs:

 CH3-ID0		CH3-ID3		CH3-ID8		CH3-ID11
CH3-ID1		CH3-ID4		CH3-ID9		CH3-ID12
CH3-ID2		CH3-ID5		CH3-ID10	CH3-ID13

Disk Drive SCSI IDs on JBOD connected to 33x0 RAID Array within a Dual-bus
configuration.

The following cabling Scheme is needed:
A)Jumper cable on RAID array from DB-port to CH:2
B)No jumper cable is required to configure a single JBOD unit for dual-bus use
C)Jumper cable from RAID array's SB-port to JBOD's Lower-Right port
D)Jumper cable from RAID array's CH:0 to JBOD's Lower-Left port.

33x0 SCSI array's disk IDs:

 CH2-ID0		CH2-ID3		CH0-ID0		CH0-ID3
CH2-ID1		CH2-ID4		CH0-ID1		CH0-ID4
CH2-ID2		CH2-ID5		CH0-ID2		CH0-ID5

JBOD Disk IDs JBOD Disk IDs JBOD Disk IDs JBOD Disk IDs

 CH2-ID8		CH2-ID11	CH0-ID8		CH0-ID11
CH2-ID9		CH2-ID12	CH0-ID9		CH0-ID12
CH2-ID10               CH2-ID13	CH0-ID10	CH0-ID13

With this configuration you can connect up to 2 hosts to CH:1 & CH:3 which are
assigned as host channels by default.

To attach a second JBOD to a 33x0 SCSI array within a Dual-bus configuration, Host Channel 3 must be reassigned as a drive channel and connected to the second JBOD.

A)Jumper cable on RAID array from DB-port to CH:2
B)No jumper cable is required between the 1st JBOD's ports
C)Jumper cable from RAID array's CH:0 port to 1st JBOD's Lower-Left port
D)Jumper cable from RAID array's SB-port (SINGL BUS CONF) to 1st JBOD's
Lower-Right port
E)Jumper cable from second JBOD's Lower-Left port to second JBOD's Upper-Right port
F)Jumper cable from RAID array's CH:3 to second JBOD's Lower-Right port

With the above configuration, the 33x0 SCSI array and 1st JBOD use a Dual-Bus
configuration. The second JBOD uses a Single-bus configuration.

33x0 SCSI array's disk IDs:

 CH2-ID0		CH2-ID3		CH0-ID0		CH0-ID3
CH2-ID1		CH2-ID4		CH0-ID1		CH0-ID4
CH2-ID2		CH2-ID5		CH0-ID2		CH0-ID5

1st JBOD's Disk IDs:

 CH2-ID8		CH2-ID11	CH0-ID8		CH0-ID11
CH2-ID9		CH2-ID12	CH0-ID9		CH0-ID12
CH2-ID10	        CH2-ID13	CH0-ID10	CH0-ID13

2nd JBOD's Disk IDs:

 CH3-ID0		CH3-ID3		CH3-ID8		CH3-ID11
CH3-ID1		CH3-ID4		CH3-ID9		CH3-ID12
CH3-ID2		CH3-ID5		CH3-ID10	CH3-ID13
