EMC Host Connectivity with QLogic FC and iSCSI HBAs and FCoE CNAs for the Linux Environment
Configuring a Boot Device on an EMC Storage Array
Configuring a VNX series or CLARiiON boot device for iSCSI 5.x
This section describes how to install an EMC-qualified version of
Linux onto an EMC VNX series or CLARiiON storage system
connected to an Intel-based x86 and x86_64 class systems and AMD
Opteron-based x86_64 class systems.
Preparing the VNX series or CLARiiON storage system
◆ It is recommended that Access Logix be enabled on the VNX
series or CLARiiON storage system for LUN masking purposes.
◆ Boot device support requires a Unisphere/Navisphere
Management station with Unisphere/Navisphere Manager or
CLI installed. The station must be separate from the server being
installed and must be networked to the VNX series or CLARiiON.
◆ Before installing Linux onto an EMC VNX series or CLARiiON
system, the array must have one bound LUN allocated to the
Storage Group for the server being installed. The LUN must be
owned by the SP connected to the boot HBA.
◆ During the installation procedure, only one LUN should be in the
boot Storage Group, so that the boot LUN may be identified
easily. After the installation, additional LUNs may be added to
the host's Storage Group.
Note: If LUNs need to be created, refer to the Unisphere/Navisphere
Management software documentation for the array type.
Preparing the host
To prepare the host:
◆ EMC recommends using port 0 on the SP for consistency.
◆ The QLogic iSCSI HBA must be the lowest-numbered PCI slot in
the server. For example, if there are three adapters in the system
in slots 2, 4, and 5, connect the cable to the adapter in slot. Do not
connect cables to other adapters until the installation is complete
and the host rebooted.
