6. In the RCU S/N box, enter the remote RCU 5-digit serial number.
7. In the Controller ID box, select the remote system’s controller ID.
8. In the Logical Adr. (RCU CU) box, enter the CU number of the RCU being added. The CU
number differs by the specified controller ID, as follows:
• When the specified controller ID is 6 (XP P9500), or 5 (XP24000/XP20000 Disk Array),
or 4 (XP12000 Disk Array or XP10000 Disk Array), you can select a CU number from
00 to FE.
• When the specified controller ID is 4 (XP12000 Disk Array or XP10000 Disk Array), you
can select a CU number from 00 to 3F.
9. In the SSID boxes, enter the SSIDs of the RCU being added. The XP P9500 uses one SSID for
each set of 256 volumes and one SSID for each set of 64 volumes or four SSIDs per CU. SSID
is 4-FFFF (hexadecimal).
10. In the MCU-RCU Path box, define the logical path between local and remote systems. You can
define a maximum of eight logical paths to an RCU.
a. In the MCU Port column, select a local system initiator port, which you previously set up.
b. In the RCU Port column, select the remote system RCU target port, also previously set up.
This establishes a logical path between the ports.
You can abbreviate the number to two characters. For example, “1A” can be entered instead
of “CL1-A”. Letters can be uppercase or lowercase.
