Upgrading Your Cisco MDS SAN-OS Software Image Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m Step 2 Issue the no ivr virtual-fcdomain-add vsan-ranges vsan-range command to disable RDI mode on all IVR enabled switches. The range of values for a VSAN ID is 1 to 4093. This can cause traffic disruption. Note Step 3 Complete Step 2 for all IVR enabled switches before moving to Step 3. Check the syslogs for any ISL that was isolated.

Upgrading Your Cisco MDS SAN-OS Software Image Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m – All SSM applications are disabled. Use the show ssm provisioning CLI command to determine what applications are configured. Use the no ssm enable feature CLI command to disable these applications. – No SSM ports are in auto mode. See the “Reconfiguring SSM Ports Before Upgrading to SAN-OS Release 3.1(2a)” section on page 14.
Downgrading Your Cisco MDS SAN-OS Software Image Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m Step 4 If the new installation or upgrade fails while copying the image and you want to keep the old (existing) image, then copy the old image (that you saved to an external server in Step 1) to the bootflash using either Fabric Manager or the copy command.
Downgrading Your Cisco MDS SAN-OS Software Image Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m – Fibre Channel Ports: Traffic on Fibre Channel ports can be nondisruptively downgraded. See Table 6 for the nondisruptive downgrade path for all SAN-OS releases. – SSM: Intelligent services traffic on the SSM, such as SANTap, NASB, and FC write acceleration, is disrupted during a downgrade. SSM Fibre Channel traffic is not.
Downgrading Your Cisco MDS SAN-OS Software Image Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m Table 6 Nondisruptive Downgrade Path from SAN-OS Release 3.1(2a) To SAN-OS Release Nondisruptive Downgrade Path SAN-OS 2.1(1a) Downgrade to SAN-OS Release 2.1(2b) and then downgrade to Release 2.1(1a). SAN-OS 2.0(4a) Downgrade to SAN-OS Release 2.1(2b) and then downgrade to Release 2.0(4a). SAN-OS 2.0(4) Downgrade to SAN-OS Release 2.

Refer to the Cisco MDS SAN-OS Release Compatibility Matrix for Storage Service Interface Images. • SSM intelligent services traffic switching on SSM ports is disrupted on upgrades or downgrades.
Limitations and Restrictions Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m Note When configuring domain interface zoning in Cisco Fabric Manager, use the MDS 9000 format for an interface name: fc slot/port. When configuring interface zoning from the command-line interface, use the bay/ext format.
Limitations and Restrictions Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m CWDM SFPs The 2-Gbps CWDM SFPs do not have have a maximum speed set in memory and they negotiate to 4-Gbps on modules that support the higher speed. As a result, the link comes up and appears to work, but then becomes disabled and connectivity problems occur. To correct this problem, both sides of the connection must have their speed hard coded to 2-Gbps.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m Reconfiguring SSM Ports Starting with Cisco MDS SAN-OS Release 3.0(1), the SSM front panel ports can no longer be configured in auto mode, which is the default for releases prior to Release 3.1(1). For instructions about how to modify the configuration of the ports before upgrading to SAN-OS Release 3.1(2a), see the “Reconfiguring SSM Ports Before Upgrading to SAN-OS Release 3.

To ensure that the port indexes between 0x0 and 0xf behave correctly, follow these steps: • 1. Issue the shut command for ports with indexes 0x200 to 0x20f. 2. Issue the shut command for the ports with indexes 0x0 to 0xf, followed by the no shut command for the same port indexes.
