SSM: Intelligent services traffic on the SSM, such as SANTap, NASB, and FC write
–
acceleration, is disrupted during an upgrade. SSM Fibre Channel traffic is not.
Gigabit Ethernet Ports: Traffic on Gigabit Ethernet ports is disrupted during an upgrade or
–
downgrade. This includes IPS modules and the Gigabit Ethernet ports on the MPS-14/2 module.
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.
IVR: With IVR enabled, you must follow additional steps if you are upgrading from Cisco
–
SAN-OS Release 2.1.(1a), 2.1(1b), or 2.1.(2a). See the
on page 16
for these instructions.
FICON: If you have FICON enabled, the upgrade path is different. See
