Be aware that some features impact whether an upgrade is disruptive or nondisruptive:
–
Fibre Channel Ports: Traffic on Fibre Channel ports can be nondisruptively upgraded. See
Table 4
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.
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 13
for these instructions.
–
FICON: If you have FICON enabled, the upgrade path is different. See
Table 4
to determine your nondisruptive upgrade path to Cisco SAN-OS Release 3.1(3). Find the
