For Fibre Channel ports, use the Edit External WWNs window. For iSCSI ports, use the Edit External iSCSI Targets window.

However, note the following:

If the current setting is error-free, it is best to continue using it.
For an external volume with host I/O, set I/O Timeout to a value no more than 15 seconds. (For details about timeout, see Detection of response delay from the external storage system and actions to take.)
For an external volume that is not used for host I/O, you can change the port settings according to the recommended values for the external storage system.
If you are going to change several parameters for the same external WWN or the same external iSCSI target, ensure that a task is completed before you perform the next task. If you perform a new task before the prior task is completed, the prior task might not be applied.

Open the External Storage window.
1. Click Storage Systems, and then expand the Storage Systems tree.
2. Click External Storage.
On the External Paths tab, select a port, and then open the window for editing port settings.
- For a Fibre Channel port, click Edit External WWNs.
- For an iSCSI port, click More Actions > Edit External iSCSI Targets.
In the Edit External WWNs or Edit External iSCSI Targets window, change the desired settings.

Note: The current values for the external WWN are displayed unless you have selected multiple paths with different values. Then the fields are blank.
Click Finish.
In the confirmation window:
1. Confirm the settings.
2. Accept the default task name or enter a unique name.
  You can enter up to 32 letters, numbers, and symbols, except these:
  \ / : , ; * ? " < > |
3. If you want to view the list of tasks for the storage system after clicking Apply, select Go to tasks window for status.
Click Apply to submit the task.
