Just updated my FS7300's from 8.7.0.9 to 8.7.0.13.
The disk is hosted by VIOS to four LPARs of IBM i. Each of the four LPARs of IBM i have 8 redundant paths to each 'drive'. On two of the four LPARs I am seeing:

The other two LPARs are fine.
No, like a dummy I did not verify these paths prior to the update. Since the data centers are hours away a quick check to see if a cable is bad by onsite checking is not an easy do.
One of the two LPARs with the issue is showing:
