Configuring the MCUs and RCUs for TrueCopy for z/OS
Operations
After you have installed the TrueCopy for z/OS hardware and software, you
can configure the MCUs and RCUs for TCz operations.
Fibre-Channel Interface Configuration
To configure the MCUs and RCUs for TCz fibre-channel operations:
1. Identify the volumes that will become the TrueCopy for z/OS M-VOLs and R-
VOLs. You need to know the storage system S/N, SSID, and CU of each
volume, so that you can configure the MCUs and RCUs correctly for your
desired pairs and async groups. When you create the pairs, you will need to
know the LDEV ID of each volume.
2. At the RCUs (i.e., remote site), use the TrueCopy for z/OS software to
configure the fibre-channel ports which are connected to the MCUs as RCU
target ports (see
Figure 3-6).
3. At the main site, connect to and log on to the USP V that you want to
configure as a TCz MCU. You must log on with Administrator or TrueCopy for
z/OS write access, and you must be in Modify mode.
4. Click Go, TrueCopy for z/OS(R), and then RCU Operation on the menu
bar of the Storage Navigator main window to display the TrueCopy for z/OS
window (RCU Operation window is displayed).
5. Configure the fibre-channel ports which are connected to the RCUs as initiator
ports (see Figure 3-6).
6. Add the desired RCU(s) to each MCU CU, and set the desired RCU options
using the Add RCU dialog box (see Figure 3-7) and RCU Option dialog box
(see Figure 3-8). Enter the following information on the Add RCU dialog box:
RCU S/N = serial number of the RCU
LDKC = the number of LDKC which the RCU belongs to (00 or 01).
Controller ID = For fibre-channel, the controller ID must be 5 (4 for
TagmaStore USP/NSC , 03 for 9900V RCU).
Logical Adr. (RCU CU) = RCU CU number (00-FE for USP V, 00-3F for
TagmaStore USP/NSC, 00-1F for 9900V)
SSID = maximum of four SSIDs per CU with 64 LDEVs per SSID. Note: If
only one
SSID is specified, there are 256 LDEVs per SSID.
Path Gr. ID = path group ID for using CU Free.
MCU-RCU path = physical port numbers (1A-2R) for each path (initiator
port-to-RCU
target port).
