EMC Host Connectivity with QLogic FC and iSCSI HBAs and FCoE CNAs for the Linux Environment
Connecting to the Storage
Zoning and connection planning in a Fibre Channel or Fibre
Channel over Ethernet environment
In a fabric environment, the user should plan for the switch topology,
target-to-hosts mapping, and the zone.
Planning procedure
The recommended procedure is as follows:
1. Draw the connectivity among the hosts, switch, and storage array
to verify the correct fabric configuration.
2. Configure the zone capability in the switch. If connecting to EMC
Connectrix, refer to the Connectrix Enterprise Storage Network
System Planning Guide for information on the zone configuration.
Establishing connectivity to the storage array
Once the adapter has been properly configured, connectivity will
need to be established between the adapter and the storage array. In
the case, where the adapter will be directly connected to the storage
array, the cable can just be attached. However, when attaching to an
FC or FCoE switch, several additional configuration steps are needed.
These include zoning the port on the adapter to the correct port on
the storage array, as well as configuring LUN Masking on the array.
◆ For additional information on how to perform these additional
installation steps, refer to the documentation located at E-Lab
Interoperability Navigator, Topology Resource Center tab, at
http://elabnavigator.EMC.com.
Note: You will need to reload the driver or reboot the server so the new
targets and LUNs may be scanned and acquired by the Linux SCSI
subsystem.
What next? Follow the instructions in “Device reconfiguration procedures for FC
and FCoE” on page 195.
