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.
