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 Symmetrix boot device for iSCSI 5.x
This section describes how to install an EMC-qualified version of
Linux onto an EMC Symmetrix storage array connected to an
Intel-based x86 and x86_64 class systems and AMD Opteron-based
x86_64 class systems.
Preparing the Symmetrix storage array
◆ It is recommended that Volume Logix be enabled on the
Symmetrix storage array for LUN masking purposes.
◆ During the installation procedure, only one LUN should be
allocated to the host, so that the boot LUN may be identified
easily. After the OS installation, additional LUNs may be
allocated.
◆ Mask a LUN on the Symmetrix to the iSCSI Qualified Name
(IQN) of the HBA port being used on the server to boot from the
Symmetrix. The IQN can be found in the BIOS of the HBA in the
Fast!UTIL Options menu. Select Configuration Settings, then
Adapter Settings.
Preparing the host
◆ 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.
◆ SCSI hard disks are allowed in SAN boot configurations.
However, the BIOS for the disk's SCSI adapters must be disabled.
Any SCSI disks attached to the host should be disconnected
during the operating system installation.
◆ For servers with SCSI CD-ROM drives, ensure that the BIOS is
enabled on the SCSI channel that includes the CD-ROM. Disable
the BIOS on any other integrated SCSI channels.
◆ For servers with IDE CD-ROM drivers, disable the BIOS on the
server's integrated SCSI adapter(s). The SCSI BIOS is not required
to boot from the CD-ROM.
