Info
Document Version Release Date Details 2 April 8, 2024 Update the Description section to include information about possible unexpected impact to the system, and added text to the Scope section to clarify that this advisory applies to all Gen6 (32G) and Gen7 (64G) switches 1 November 1, 2023 Original Document Release On HPE 3PAR StoreServ 8000, 9000, and 20000 storage arrays connected using 16Gbps FC HBAs to a Brocade/Broadcom SAN switch Fabric Operating System (FOS) version 9.x firmware, a rare instability might occur. IMPORTANT : Current information indicates that this instability occurs during a port sync phase, in which the switch is checking if it might be an E-port coming online. The port, in this state, may report as functional in both the SAN and the storage array, but the host data path is not functioning normally. This could cause unexpected impact, including data integrity. To avoid this issue, HPE recommends disabling the E-port capability on the SAN switch port for all 16Gbps storage and replication device ports. As a proactive measure, customers with 16G HBAs and Brocade FOS 9.x should disable E-Port functionality on Brocade switch ports.
Scope
This advisory applies to HPE 3PAR StoreServ 8000, 9000, and 20000 Storage arrays running 3.x.x connected via 16G HBAs to any Brocade Switches running FOS firmware version 9.x. These include all Gen6 (32G) and Gen7 (64G) switches.
Resolution
If the following workaround does not completely clear the issue, open a case with HPE Support. NOTE : Action taken to prevent this issue is only to avoid the instability occurrence and may not completely resolve the issue. Execute the portcfgeport [slot/] port [-p] command in the FC host port. The different modes (0, 1, 2) specify the E-port configuration: 0 - Disables E-port capability for the specified ports. <<< correct setting 1 - Enables the ports as E-port. This is the default port state . 2 - Locks down the ports as E-port This command effectively disables the port's E-port capability. NOTE : Disabling the E-port's capability will force a flogi , and you will need to disable the capability on one port at a time. For example, if an array is connected on slot 1 port 7, use the following command: portcfgeport 1/7 0 IMPORTANT : The recommendation to disable E-port capability one at a time only applies if both of the following conditions are met: Brocade/Broadcom SAN switches running a FOS 9.x firmware version HPE Storage Array models whose maximum Fibre Channel port speed is 16 Gbps or lower RECEIVE PROACTIVE UPDATES : Receive support alerts (such as Customer Advisories), as well as updates on drivers, software, firmware, and customer replaceable components, proactively in your e-mail through HPE Support Alerts.
