vSphere Storage
Change the Path Selection Policy in the vSphere Client
Generally, you do not have to change the default multipathing settings your host uses for a specific storage
device. However, if you want to make any changes, you can use the Manage Paths dialog box to modify a path
selection policy and specify the preferred path for the Fixed policy.
Procedure
1 Open the Manage Paths dialog box either from the Datastores or Devices view.
2 Select a path selection policy.
By default, VMware supports the following path selection policies. If you have a third-party PSP installed
on your host, its policy also appears on the list.
n Fixed (VMware)
n Most Recently Used (VMware)
n Round Robin (VMware)
3 For the fixed policy, specify the preferred path by right-clicking the path you want to assign as the
preferred path, and selecting Preferred.
4 Click OK to save your settings and exit the dialog box.
