Last updated on OCTOBER 05, 2022

Applies to:

Brocade DCX Backbone - Version All Versions and later
Information in this document applies to any platform.


There are several Solaris 10 servers with Oracle Emulex FC HBA LPe16002-M6 connected to the SAN (Brocade switches)
accessing disks and tape devices.

From time to time there are link down / link up messages

Bottleneck detection detects latency towards the device attached to the port. MAPS throws up some events, and as well recovery resets the link, and finally the bottleneck detector announces latency bottleneck is cleared.



FC HBA was replaced and problem persist.
