Cisco MDS 9000 Family Release Notes for Storage Services Interface Image Release 4.2(3k)
OL-20651-07
Compatibility Matrix
Configuring SSM Ports in Auto Mode
Starting with Cisco MDS SAN-OS Release 3.0(1), the SSM front panel ports can no longer be
configured in auto mode. Because auto mode is the default for releases prior to Release 3.0(1), you
should modify the configuration of the ports before upgrading the SAN-OS software image to NX-OS
Release 4.2(3a) to avoid any traffic disruption.
For information on how to reconfigure the SSM ports, refer to the “Reconfiguring SSM Ports Before
Upgrading to NX-OS Release 4.2(3a)” section of the Cisco MDS 9000 Family Release Notes for Cisco
MDS NX-OS Release 4.2(3a).
Compatibility Matrix
Before upgrading your SSI image, refer to the Cisco MDS NX-OS Release Compatibility Matrix for
Storage Service Interface Images, and to Table 11 in the MDS 9000 Family Release Notes for NX-OS
Release 4.2(3a). Use Table 11 to determine your nondisruptive upgrade path to Cisco MDS NX-OS
Release 4.2(3k).
Note If you are using SANTap in your environment, you cannot upgrade directly from SAN-OS Release 3.3.x
to NX-OS Release 4.2. The only supported upgrade path for SANTap environments is from SAN-OS
Release 3.3.x to NX-OS Release 4.1.x to NX-OS Release 4.2.
