EMC Host Connectivity with Emulex FC HBAs and FCoE CNAs for the Linux Environment

Configuring a Boot Device on an EMC Storage Array

local disks in the system, you may be forced (depending on how

Linux discovers the drives) to put your boot block onto a local

disk.

◆ Some servers present the option of disabling the local drive. If the

local drive is disabled, then verify that the boot block is installed

on the first EMC storage array device seen by the Linux host.

Symmetrix-specific limitations

The following are Symmetrix-specific limitations:

◆ When attached to a Symmetrix, the physical-to-logical split must

be such that you meet the minimum required disk space required

to install the Linux operating system. Refer to your Linux

distribution guide for these requirements.

◆ Prior to the installation on a Symmetrix LUN, the Linux host HBA

must have successfully logged into the array. Using Solutions

Enabler from another host, at least one LUN must be assigned to

the host.

◆ During the installation procedure, it is recommended, but not

required, that only one LUN be allocated to the host for ease of

use. Once the installation has completed, additional LUNs may

be assigned to the host.

◆ For RHEL 4.5, boot from a LUN with the VCM gatekeeper

existing on a Symmetrix, you may receive an "unhandled

exception with ZeroDivisionError" message when partitioning

the boot LUN. Remove the VCM gatekeeper from the FA port and

the installation will be successful.

VNX series- and CLARiiON-specific limitations

The folloiwng are VNX series- and VNX series- or

CLARiiON-specific limitations:

◆ Prior to the installation on a VNX series or CLARiiON LUN, the

Linux host must have been manually registered on the array and

assigned to a Storage Group. At least one LUN must be bound to

the host’s Storage Group and owned by the SP connected to the

HBA being used for the fabric boot. The lowest-numbered path to

the boot LUN must be the active path.

◆ It is required that the boot LUN be assigned Host LUN ID 0.
