- Once the 9513 is upgraded to NX-OS with Fabric-2 modules and reloaded, a downgrade to SAN-OS will be disruptive. It is recommended for the pair of Fabric modules to be of the same model. Mixing Fabric-1 and Fabric-2 modules with SAN-OS is supported.
ADDITIONAL MOUNTING REQUIREMENTS C-Series Fabric Switches can be installed in all HP standard racks. Please note the following restrictions: Side-Rail Rack-Mounted Options All side-rail rack-mounted options must have a minimum of four (4) inch clearance distance above or below the switch chassis for the C-Series MDS 9500 Series Multilayer Directors and MDS 9200 Series Multilayer Fabric Switches. Side-rail rack-mount options include HP zero-U options, KVM switches and power distribution units (PDUs).
SERIAL PORT You must use the serial interface to configure a switch IP address. Refer to the Cisco MDS 9000 Family Configuration Guide for instructions on how to connect the serial port to a host machine. INITIAL INSTALLATION RECOMMENDATIONS/REQUIREMENTS The C-Series MDS 9000 Family of switches does not automatically allow SAN connectivity for the first-time, out-of-the box power up. For more comprehensive initial setup information, please refer to the Cisco documentation found at http://www.cisco.com.
IV. Enable In-Order Delivery of Frame During a steady-state environment, the hardware and software architecture of the C-Series MDS 9000 Family prevents out-of-order (OOO) frame distribution from occurring. If the fabric encounters a failure, some devices may not be able to handle any OOO frames. For this reason, HP requires in-order delivery (IOD) be enabled for all switches. There is a switch setting to enable in-order of frames during fabric failure.
FABRIC MANAGER & DEVICE MANAGER GUI SETUP The optional Cisco Fabric/Device Manager GUI (graphical user interface) is a Java application. The Fabric/Device Manager installation process is based on requirements for installing Java Web Start. Refer to the Cisco MDS 9000 Fabric Manager Release Notes for system requirements and installation instructions. To install Device Manager, use a web browser to make an http:// connection to the IP address of a C-Series switch.
CISCO MDS 9000 N-PORT VIRTUALIZATION (NPV) MODE N-Port Virtualization (NPV) Mode is a software feature that can be optionally enabled on the CSeries MDS 9124 and the MDS 9124e Fabric Switches. Switches operating in NPV mode do not join a fabric; rather, they pass traffic between NPV core switch links and end devices. NPV technology addresses the increase in the number of domain IDs needed to deploy a large number of ports by making the MDS 9124 and the MDS 9124e behave as a host to the core FC switch.
HP VIRTUAL CONNECT FIBRE CHANNEL MODULE FOR C-CLASS BLADESYSTEM AND QLOGIC MEZZANINE HBAS When using Qlogic mezzanine HBAs with Virtual Connect on the same C-Series switch with its target on the same switch/VSAN, NPIV addresses are limited to 256. To scale beyond 256 addresses, for proper operation the C-Series switch commands below must be executed on the VSAN to which VC-FC is connected.
CISCO MDS 9000 STORAGE MEDIA ENCRYPTION (SME) Overview The SME solution is a comprehensive network-integrated encryption service with enterprise-class key management that works transparently with existing and new SANs. The innovative networkintegrated solution has numerous advantages over competitive solutions available today: • SME installation and provisioning are both simple and non-disruptive. Unlike other solutions, SME does not require rewiring or SAN reconfiguration.
FC AND FCIP WRITE ACCELERATION FEATURE MUST NOT BE ENABLED WHEN IMPLEMENTING CONTINUOUS ACCESS ENTERPRISE VIRTUAL ARRAY Continuous Access Enterprise Virtual Array includes an FC/FCIP write acceleration feature. For this reason, Cisco’s FC and FCIP write acceleration must not be enabled in a Continuous Access EVA environment. By default Cisco NX-OS write acceleration is disabled. FCIP TAPE ACCELERATION NX-OS FCIP Tape Acceleration (Write & Read) is disabled by default.
5. Enter the following command to enable the VSAN(s) that contain the Continuous Access EVA and/or DRM fabric to src-dst-id loadbalancing: switch(config-vsan-db)# vsan <1-4094> loadbalancing src-dst-id switch(config-vsan-db)# exit switch(config)# exit 6.
C-SERIES MDS 9124e FABRIC SWITCH FOR HP C-CLASS BLADESYSTEM The MDS 9124e 12-port fabric switch and the MDS 9124e 24-port fabric switch for HP c-Class BladeSystem have fixed configurations with 8-internal/4-external or 16-internal/8-external full rate 4-Gbps fibre channel ports. The 12-port switch can be upgraded to the 24-port switch with a software expansion license. Note: Refer to HP.com for the latest supported software for the fibre channel adapters and c-Class Onboard Administrator firmware.
UPGRADE FROM 2GB FIBRE CHANNEL SWITCHING MODULES TO 4GB FIBRE CHANNEL SWITCHING MODULES C-Series MDS 2Gb switch modules in 16-port and 32-port configurations and the 14/2 Multiprotocol Services module have approached their end of life and will no longer be sold. Customers wishing to upgrade to 4Gb technology to replace the older 2Gb modules can purchase 4Gb modules in a 12, 24, or 48-port configurations to replace the 2Gb 16 or 32-port modules.
UPGRADE FROM 14/2 MULTIPROTOCOL SERVICES MODULE TO 18/4 MULTISERVICE MODULE The replacement of the 14/2 Multiprotocol Services module with the 18/4 Multiservice module must be treated as an upgrade. Considerations must be taken to ensure that the configuration can be implemented on the new module. Please refer to the Cisco MDS 9000 CLI Configuration Guide for procedures to configure the new modules.
HP SPECIFIC KNOWN ISSUES Problem Description: Issuing an fcping to the EVA4400 may crash the EVA controller Workaround: None. Problem Description: If it becomes necessary to move an EVA controller port to a different port on the same C-Series switch, or to a port on a different C-Series switch, the corresponding controller port may become unavailable. Workaround: Restart the EVA controller. Problem Description: EVA controllers running VCS 3.
