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

Configuring a Boot Device on an EMC Storage Array

Limitations

This section contains the following limitation information:

◆ “Common limitations” on page 124

◆ “Symmetrix-specific limitations” on page 126

◆ “VNX series- and CLARiiON-specific limitations” on page 126

Common limitations

Boot configurations must not deviate from the following limitations

established by EMC:

◆ LUN 000 must exist on the EMC storage array in order for the

SCSI layer to scan all devices on RHEL 4 (all releases), SLES 9 SP1,

and Asianux 2.0. In these distributions, the v2.6.x kernel does not

allow scanning past a nonexistent LUN 000.

Note: This issue has been resolved with SLES 9 SP2 and RHEL 4 U3.

Note: It is recommended that SPC-2 and the SC3 bit be set on the

Symmetrix FA ports attached to the host.

◆ The EMC Storage device must have enough disk space to hold the

Linux operating system.

◆ A maximum of 32 volumes may be configured on the EMC

storage array port that will be used to boot Linux.

◆ EMC recommends that you install, rather than upgrade, the

kernel-source and kernel UP, SMP, and enterprise RPMs.

◆ Linux hosts booting from an EMC storage array are limited to the

use of one HBA.

◆ Hosts booting from an EMC storage array must use the Emulex

driver as a module, not statically linked into the kernel.

◆ Only 32-bit SLES 8 hosts are supported booting from an EMC

storage array. 64-bit architectures are not supported.
