Changing the port settings of an external storage system

You can change the port settings of an external system.

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 normal I/O, set I/O Timeout from 5 - 15 seconds.
  • Use the external system's recommended values for other port settings.
  • 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.

Before you begin

  • You must have the Storage Administrator (Provisioning) role.
