Registering the system ports with the EMC CLARiiON

If Access Logix is installed, you must register the system ports with an EMC CLARiiON controller.

The following prerequisites must be met before you can register the system ports with an EMC CLARiiON controller that has Access Logix installed:

Each initiator port [worldwide port name (WWPN)] must be registered against a host name and against a target port to which access is granted. Refer to Default and required settings for registering system ports with the EMC CLARiiON.. If a host has multiple initiator ports, multiple table entries with the same host name are listed. If a host is allowed access by using multiple target ports, multiple table entries are listed. For system hosts, register all WWPN entries with the same host name.

Default and required settings for registering system ports with the EMC CLARiiON. lists the associations:
Table 1. Default and required settings for registering system ports with the EMC CLARiiON.
Option EMC CLARiiON default setting Required system setting
WWPN N/A Any
WWN N/A Any
Host name N/A Any
SP port N/A Any
Initiator type 3 3
ArrayCommPath Enable Disable
Failover mode 0 2
Unit Serial Number Array Array
  1. Connect the Fibre Channel and zone the fabric as required.
  2. Issue the detectmdisk command-line interface (CLI) command.
  3. Right-click on the storage system from the Enterprise Storage window.
  4. Select Connectivity Status.
    The Connectivity Status window is displayed.
  5. Click New.
    The Create Initiator Record window is displayed.
  6. Wait for the list of system ports to appear in the dialog box. Use the WWPN to identify them.
    This process can take several minutes.
  7. Click Group Edit.
  8. Select all instances of all the system ports in the Available dialog box.
  9. Click the right arrow to move them to the selected box.
  10. Complete the HBA WWN field.
    You must know the following information:
    • WWNN of each system node in the clustered system
    • WWPN of each port ID for each node on the system
    The HBA WWN field is made up of the WWNN and the WWPN for the system port. The following output is an example: 
    50:05:07:68:01:00:8B:D8:50:05:07:68:01:20:8B:D8
  11. Select A in the SP field, and 0 in the SP Port field.
  12. Select CLARiiON Open in the drop-down list of the Initiator Type field.
  13. If the ArrayCommPath check box is selected, clear it.
  14. Select 2 in the drop-down list of the Failover Mode field.
    Attention: Failure to select failover mode 2 prevents the system from being able to fail over I/O. If a single failure occurs, your data might become unavailable.
    1. If this time is the first time that a port was registered, ensure that you select the New Host option. Otherwise, select Existing Host.
    2. Ensure that the same host name is entered for each port that is registered.
  15. Select Array in the drop-down list of the Unit Serial Number field.
  16. Assign a host name in the Host Name field.
  17. Click OK.
  18. Specify the IP address of your switch.
    The EMC CLARiiON does not use this IP address. However, it must be unique (within the EMC CLARiiON) to prevent errant behavior by Navisphere.
  19. Repeat step #svc_registeringwwpns_29eidk/sp for all possible combinations.
    The following example shows the different combinations of a system with four ports:
    • SP: A SP Port: 0
    • SP: A SP Port: 1
    • SP: B SP Port: 0
    • SP: B SP Port: 1
  20. Repeat steps #svc_registeringwwpns_29eidk/storagesub to #svc_registeringwwpns_29eidk/spb to register the rest of your system WWPNs.

All your WWPNs are registered against the host name that you specified.
