Gigabit Ethernet Ports: Traffic on GigabitEthernet/IPStorage ports is disrupted during an upgrade or downgrade.
This includes the Gigabit Ethernet ports on the MSM-18/4 module, the MDS 9222i switch, the MDS 9000 16-Port
Storage Services Node (SSN-16), and the IPStorage ports in MDS 9250i. Those nodes that are members of VSANs
traversing an FCIP ISL are impacted, and a fabric reconfiguration occurs. iSCSI initiators connected to the Gigabit
Ethernet ports lose connectivity to iSCSI targets while the upgrade is in progress.
