Configuring Fibre Channel ports

Use this procedure to set the topology (FC-AL or P-to-P) of a Fibre Channel port.

Procedure

1. Click Storage Systems, and then expand the Storage Systems tree.

2. Click Ports/Host Groups/iSCSI Targets.

3. In the Ports/Host Groups/iSCSI Targets window, click the Ports tab.

4. Select the desired port, and then click Edit Ports.

5. Under Connection Type, select FC-AL or P-to-P.

6. Click Finish.

   The Confirm window opens.

7. In the Task Name text box, type a unique name for the task or accept the default.

   You can enter up to 32 ASCII characters and symbols, with the exception of: \ / : , ; * ? " < > |. The value <date>-<window name> is entered by default.

8. Click Apply.

   If the Go to tasks window for status check box is selected, the Tasks window appears.

Procedure

1. Click Storage Systems, and then expand the Storage Systems tree.

2. Click Ports/Host Groups/iSCSI Targets.

3. In the Ports/Host Groups/iSCSI Targets window, click the Ports tab.

4. Select the desired port, and then click Edit Ports.

5. In the Edit Ports window, select the Port Speed check box, and then select the desired port speed.

   Select the speed of the Fibre Channel port in the unit of Gbps (Gigabit per second). If Auto is selected, the storage system automatically sets the speed to 4, 8, 16 or 32 Gbps.
   CautionObserve the following cautions when setting speed on a Fibre Channel port:

   • If they support 4, 8, 16 or 32 Gbps, use 4, 8, 16 or 32 Gbps for the CHB(FC) port speed, respectively.
   • If the Auto Negotiation setting is required, some links might not be up when the server is restarted. Check the channel lamp. If it is flashing, disconnect the cable, and then reconnect it to recover from the link-down state.
   • If the CHB(FC) port speed is set to Auto, some equipment might not be able to transfer data at the maximum speed.
   • When you start a storage system, HBA, or switch, check the host speed appearing in the Port list. If the transfer speed is different from the maximum speed, select the maximum speed from the list on the right, or disconnect, and then reconnect the cable.

   • The available port speed which is specified in Port Speed is limited due to the combination of the type of the Fibre Channel port and the topology which is specified in Connection Type.

6. Click Finish.

   The Confirm window appears.

7. In the Task Name text box, type a unique name for the task or accept the default.

   You can enter up to 32 ASCII characters and symbols, with the exception of: \ / : , ; * ? " < > |. The value <date>-<window name> is entered by default.

8. Click Apply.

   If the Go to tasks window for status check box is selected, the Tasks window appears.

Enabling LUN security

In the following example, LUN security is enabled on port CL1-A. The two hosts in the hg-lnx host group can access only three LUs (00:00:00, 00:00:01, and 00:00:02). The two hosts in the hg-hpux host group can access only two LUs (00:02:01 and 00:02:02). The two hosts in the hg-solar host group can access only two LUs (00:01:05 and 00:01:06).

Disabling LUN security

Typically, you do not need to disable LUN security on ports. For example, if LUN security is disabled on a port, the connected hosts can access only the LUs associated with host group 0, and cannot access LUs associated with any other host group.

Host group 0 is the only host group reserved, by default, for each port. If you use the LUN Manager window to view a list of host groups in a port, host group 0, indicated by the number 00, usually appears at the top of the list.

The default name of host group 0 consists of the port name, a hyphen, and the number 00. For example, the default name of host group 0 for port 1A is 1A-G00. However, you can change the default name of the host group 0.

LUN security is disabled, by default, on each port. When you configure your storage system, you must enable LUN security on each port to which hosts are connected.
