REFER TO THE CISCO NX-OS RELEASE NOTES FOR A
COMPLETE LIST OF NEW FEATURES AND OTHER
INFORMATION PERTINENT TO THIS RELEASE
As part of the NX-OS 4.1(1c) image updates provided by HP, the Cisco MDS 9000 Family
Release Notes for NX-OS 4.1(1c) have been included in the bundle. For a complete list and
detailed description of features included in the NX-OS 4.1(1c) release, refer to the Cisco release
notes as appropriate.
REBRANDING OF SAN-OS TO NX-OS
Cisco MDS 9000 SAN-OS Software is rebranded to Cisco MDS 9000 NX-OS Software starting
with release 4.1(1b). Software prior to NX-OS 4.1(1b) will continue using the name “SAN-OS”
and remain on the 3.x code stream. NX-OS is designed to interoperate with switches running
SAN-OS software.
When mixing NX-OS, SAN-OS, and FabricWare in the same fabric, HP strongly recommends
upgrading all fabric switches to the latest supported software version in order to maintain a
consistent version throughout the SAN. All switches in the same major NX-OS/SAN-
OS/FabricWare family must use the same software version. Two successive NX-OS/SAN-
OS/FabricWare versions can be used in a fabric temporarily while upgrading switch software.
Do not enable new switch features until the upgrade is complete. For new NX-OS features,
switch limitations, and caveats, refer to the Cisco MDS 9000 Family Release Notes.
Fabric Manager is not embedded in the NX-OS software. Fabric Manager is available from a
CD-ROM that ships with the switch, provided by HP in the NX-OS image bundle, or by
requesting a CD through HP SUM. Fabric Manager Update Installer is provided in the HP SAN-
OS image bungle.
