Setting the T10 PI mode on a port

Before you begin

  • The Storage Administrator (Provisioning) role is required to perform this task.
  • Access to the CHB(FC) Fibre Channel board port is required.
  • The port speed must be 16 Gbps or 32 Gbps.

Caution

If you change the T10 PI mode of one port, the T10 PI mode of the other port paired with changed port also needs to be changed. You must verify the mode of each port in the pair before changing the T10 PI mode. Make sure the ports in each pair are the same in the resource group. The following shows pairs of port IDs.

If you change the setting on one of the ports in the pair, the setting on the other port in the pair will also be changed:

  • Port IDs 1x and 3x (where x is a letter from A to R). For example, 1A and 3A can be paired with each other.
  • Port IDs 2x and 4x (where x is a letter from A to R). For example, 2B and 4B can be paired with each other.
  • If the T10 PI mode of the CHB port of the 4HF32R package, port IDs 1x, 3x, 5x, and 7x (where x is a letter from A to R) are collectively changed.
NoteIf the T10 PI mode is enabled between the path of the target port and LDEV, you cannot disable the T10 PI mode of the port.

Procedure

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

  2. Click Ports/Host Groups/iSCSI Targets.

  3. Select the Ports tab.

  4. Select the desired port.

    To collectively change the T10 PI mode of ports, do not intermix ports with enabled or disabled T10 PI modes.

  5. Click Edit Ports.

  6. Click OK on the message window.

  7. Select Enable or Disable on the Edit T10 PI Mode window.

  8. Click Finish. The Confirm window appears.

  9. In the Confirm window, confirm the settings. In the Task Name, type a unique name for this task or accept the default, then click Apply. If Go to tasks window for status is checked, the Tasks window opens.

  • Managing logical volumes

    After provisioning your system, you can begin to manage open-system logical volumes. Managing logical volumes includes tasks such as configuring hosts and ports, configuring LU paths, setting LUN security on ports, and setting up Fibre Channel authentication. LUN Manager is required to manage logical volumes.
