Is a link broken between two pdisks?
NO
No trouble found.

a. Find the devices that are on each side of the broken link. The Identify
function, which is available on this display, helps you to find the
locations of pdisks. See “Finding the Physical Location of a Device” on
page 409 if you need more information about finding the disk drive.
b. Go to “SSA Link Errors” on page 478. The information that is provided
there can help you solve the problem. For information on how to
identify and exchange the FRU, see the service information for the
enclosure that contains the device.
