Cisco MDS 9000 Family Release Notes for Cisco MDS SAN-OS Release 3.2(3)

OL-14116-04

Upgrading Your Cisco MDS SAN-OS Software Image

–

Fibre Channel Ports: Traffic on Fibre Channel ports can be nondisruptively upgraded. See

Table 5 for the nondisruptive upgrade path for all SAN-OS releases.

–

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,

the MSM-18/4 module, and the MDS 9222i switch. 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.

–

Inter-VSAN Routing (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 “Upgrading with

IVR Enabled” section on page 15 for these instructions.

–

FICON: If you have FICON enabled, the upgrade path is different. See Table 6.

Use Table 5 to determine your nondisruptive upgrade path to Cisco SAN-OS Release 3.2(3). Find the

image release number you are currently using in the Current column of the table and use the path

recommended.

Note The software upgrade information in Table 5 applies only to Fibre Channel switching traffic. Upgrading

system software disrupts IP traffic and SSM intelligent services traffic.
