Active path information (I/O) is missing after patching an ESXi host

In the storage path Information window, you normally find a list looking like below. It shows “Active path” and “Active Path (I/O)”:

If you are missing the “Active path (I/O)” Information after patching/upgrading your ESXi hosts do not panic.

As described in VMware KB “Active path information (I/O) missing after update to 6.0 Update 3 (2149992)” this behavior is not normal, but only a cosmetic issue.

After patching: no more “Active (I/O)”

VMware KB lists the following symptoms for this issue:

  • The ESXi host has been updated to 6.0 Update 3.
  • This issue appears in the vSphere Client and vSphere Web Client.
  • Storage path information does not display which path is active (I/O).
  • Preferred path information is not seen using PSP Fixed.

Unfortunately, there is no workaround or resolution available for this issue at the moment.
