You must register the SAN Volume Controller ports
with an EMC CLARiiON controller if Access Logix is installed.
The following prerequisites must be met before you can register
the
SAN Volume Controller ports
with an EMC CLARiiON controller that has Access Logix installed:
- The EMC CLARiiON controller is not connected to the SAN Volume Controller
- You have a RAID controller with LUs and you have identified which
LUs you want to present to the SAN Volume Controller
Each initiator port [worldwide port name (WWPN)] must
be registered against a host name and against a target port to which
access is granted. If a host has multiple initiator ports, multiple
table entries with the same host name are listed. If a host is allowed
access using multiple target ports, multiple table entries are listed.
For SAN Volume Controller hosts,
all WWPN entries should carry the same host name.
The following
table lists the associations:

- Connect the fibre channel and zone the
fabric as required.
- Issue the svctask detectmdisk command-line interface
(CLI) command.
- Right-click on the storage system from the Enterprise Storage
window.
- Select Connectivity Status. The
Connectivity Status window is displayed.
- Click New. The Create Initiator
Record window is displayed.
- Wait for the list of SAN Volume Controller ports
to appear in the dialog box. Use the WWPN to Identify them. This can
take several minutes.
- Click Group Edit.
- Select all instances of all the SAN Volume Controller ports
in the Available dialog box.
- Click the right arrow to move them to the selected box.
- Fill in the HBA WWN field. You must
know the following information:
- WWNN of each SAN Volume Controller in
the cluster
- WWPN of each port ID for each node on the cluster
The HBA WWN field is made up of the WWNN and the WWPN for the SAN Volume Controller port.
The following is an example of the output:50:05:07:68:01:00:8B:D8:50:05:07:68:01:20:8B:D8
- Select A in the field marked SP and 0 in the SP Port field.
- Select CLARiiON Open in the drop
down list of the Initiator Type field.
- Deselect the ArrayCommPath checkbox if it has been selected.
- Select 2 in the drop down list of the Failover
Mode field.
Attention: Failure
to select failover mode 2 prevents the SAN Volume Controller from
being able to failover I/O. Your data might become unavailable in
the event of a single failure.
- If this is the first time that a port has been registered,
ensure that you select the New Host option. Otherwise, select Existing
Host.
- Ensure that the same host name is entered for each port
that is registered.
- Select Array in the drop down list
of the Unit Serial Number field.
- Assign a host name in the Host Name field.
- Click OK.
- 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.
- Repeat step 11 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
- Repeat steps 1 to 19 to register the rest
of your SAN Volume ControllerWWPNs.
All your WWPNs are registered against the host name that
you specified.
