Instructions

Per Cisco release notes for MDS series switches:

General Upgrading Guidelines
Follow these general guidelines before performing a software upgrade:
  • Review the non-disruptive upgrade path to Release 6.2(17) in Table 13.
  • Install and configure dual supervisor modules before the upgrade.
  • Issue the show install all impact upgrade-image CLI command to determine if your upgrade will be non-disruptive.
  • Be aware that some features impact whether an upgrade is disruptive or non-disruptive:
  Fibre Channel Ports: Fibre Channel ports can be non-disruptively upgraded without affecting traffic on the ports. SeeTable 13 for the nondisruptive upgrade path for all NX-OS and SAN-OS releases.

  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-PortStorage Services Node (SSN-16), and the IPStorage ports in MDS 9250i. Those nodes that are members of VSANstraversing an FCIP ISL are impacted, and a fabric reconfiguration occurs. iSCSI initiators connected to the GigabitEthernet ports lose connectivity to iSCSI targets while the upgrade is in progress.
