Add bidirectional remote connections between the primary and secondary storage systems. Specify the same path group ID to the bidirectional remote connections. If you add remote connections when remote connections already exist for performing GAD pair operations, due to a bandwidth shortage or another reason for example, use ports that are not used for the existing remote connections. If you add remote connections by using the ports that are already used for the existing remote connections, host I/Os to the GAD pair might be temporarily stopped.

Note:

To specify serial numbers in CCI commands:

For VSP One Block 85, add "9" to the beginning of the serial number (6 digits in total). For example, enter 912345 to specify serial number 12345.
For VSP 5000 series, add "5" to the beginning of the serial number (6 digits in total). For example, enter 512345 to specify serial number 12345.

To specify storage system models in CCI commands:

For VSP One Block 85 storage systems, enter RH20ETP.
For VSP One Block 20 series models, enter M800.
For VSP 5000 series models, enter R900.
For VSP E series, VSP G130, G/F350, G/F370, G/F700, G/F900, VSP Gx00 models, or VSP Fx00 models, enter M800.

When viewing storage systems in CCI command output:

VSP One Block 85 models are displayed as RH20ETP in command output.
VSP One Block 20 series models are displayed as M8 in command output.
VSP 5000 series models are displayed as R9 in command output.
VSP E series, VSP G130, G/F350, G/F370, G/F700, G/F900, VSP Gx00 models, and VSP Fx00 models are displayed as M8 in command output.

Add a remote connection with path group ID 0 from primary storage system port (CL3-A) to secondary storage system port (CL3-C).
```
raidcom add rcu -cu_free 822222 M800 0 -mcu_port CL3-A -rcu_port CL3-C -IH0
```

Confirm that asynchronous command processing has completed.

raidcom get command_status -IH0
HANDLE   SSB1    SSB2    ERR_CNT      Serial#   Description
00c3        -       -          0       811111   -

Add a remote connection with path group ID 0 from secondary storage system port (CL4-C) to primary storage system port (CL4-A).
```
raidcom add rcu -cu_free 811111 M800 0 -mcu_port CL4-C -rcu_port CL4-A -IH1
```

Confirm that asynchronous command processing has completed.

raidcom get command_status -IH1
HANDLE   SSB1    SSB2    ERR_CNT      Serial#   Description
00c3        -       -          0       822222   -

Add the redundant paths between the storage systems using the raidcom add rcu_path command. These redundant paths are not shown in the illustration.

Check command and output examples

On the primary storage system, display remote connection information.

raidcom get rcu -cu_free 822222 M800 0 -IH0
Serial# ID  PID  MCU RCU  M/R T  PNO  MPORT  RPORT  STS_CD  SSIDs ...
 822222 M8    0    -   -  RCU F    0  CL3-A  CL3-C  NML_01  -

On the secondary storage system, display the remote connection information, and confirm that the serial number, model, and port name of the storage system are correct and that the path status is normal.

raidcom get rcu -cu_free 811111 M800 0 -IH1
Serial# ID  PID  MCU RCU  M/R T  PNO  MPORT  RPORT  STS_CD  SSIDs ...
 811111 M8    0    -   -  RCU F    0  CL4-C  CL4-A  NML_01  -
