Cisco MDS 9000 Series Release Notes, Release 7.3

General Upgrading Guidelines

Follow these general guidelines before performing a software upgrade:

• Install and configure dual supervisor modules before the upgrade.
• Issue the show install all impact upgrade-image command to determine if your upgrade will be nondisruptive.
• Be aware that some features are impacted whether an upgrade is disruptive or nondisruptive:

– Fibre Channel Ports : Fibre Channel ports can be nondisruptively upgraded without affecting traffic on the ports. See Table 2 for the nondisruptive upgrade path for all MDS NX-OS releases.

– Gigabit Ethernet Ports : Traffic on Gigabit Ethernet or IPStorage ports are disrupted during an upgrade or downgrade. This includes the Gigabit Ethernet ports on the MDS 9000 16-Port Storage Services Node (SSN-16), IPStorage ports on the MDS 9250i, MSM-18+4 Module, and Cisco MDS 24/10 Port SAN Extension Module. 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.

Note In addition to these guidelines, you may want to review the information in the “Limitations and Restrictions” section prior to a software upgrade to determine if a feature may possibly behave differently following the upgrade.

Generation 2 modules or switches can have one or more ports in port groups that share common resources such as bandwidth and buffer credits. If this command fails, reduce the number of zones, IVR zones, TE ports, or a combination of these in the system and issue the command again.
• Disable all features that are not supported by the downgrade release. Use the show incompatibility system downgrade-image command to determine what you need to disable.
• Use the show install all impact downgrade-image command to determine if your downgrade will be nondisruptive.
• Be aware that some features impact whether a downgrade is disruptive or nondisruptive:

– Fibre Channel Ports : Fibre Channel ports can be nondisruptively downgraded without affecting traffic on the ports.

– Gigabit Ethernet Ports : Traffic on Gigabit Ethernet or IPStorage ports is disrupted during a downgrade. This includes the Gigabit Ethernet ports on the MDS 9000 16-Port Storage Services Node (SSN-16), IPStorage ports in MDS 9250i, MSM-18+4 module, and 24/10 Port SAN Extension Module. 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 downgrade is in progress.

Find the NX-OS or SAN-OS image that you want to downgrade to in the To NX-OS or SAN-OS Release column of the table and follow the steps in the order specified to perform the downgrade.

Note The software downgrade information in the below tables applies only to Fibre Channel switching traffic. Downgrading system software disrupts IP and intelligent services traffic.
