3.Enter the device data for each disk array device in a table. See “Path worksheet” on page 62.

4.Construct the device file name for each device, using the device information, and enter the file names in your table. Use the following formula to construct the device file name:

cxtydz where

x= SCSI bus instance number

y= SCSI target ID

z= LUN

c stands for controller, t stands for target ID, and d stands for device. The numbers x, y, and z are hexadecimal.

Example

SCSI bus
instance number	Hardware path	SCSI TID	LUN	File name
00	14/12.6.0	6	0	c6t0d0
00	14/12.6.1	6	1	c6t0d1

5.Verify that the SCSI TIDs correspond to the assigned port address for all connected ports (see mapping tables on page 63 in Appendix B, for values). If so, the logical devices are recognized properly.

If the logical devices are not recognized properly:

•Check the AL-PA for each port using the LUN Manager software.

•If the same port address is set for multiple ports on the same loop (AL with HUB), all port addresses except one changed to another value, and the relationship between AL-PA and TID does not correspond to the mapping given in Appendix B (page 63), set a
