Configuring a Boot Device on an EMC Storage Array

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 for these requirements.

For RHEL 4.5 boot from a LUN with 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- or CLARiiON-specific limitations

Consider the following 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 adapter being used for the fabric boot. The VNX series or CLARiiON storage system SP should be zoned to the lowest-numbered channel in the server and the lowest-numbered path to the boot LUN must be the active path.

EMC recommends, although it is not required, that the boot LUN be assigned Host LUN ID 0.

During the installation procedure, it is recommended, but not required, that only one LUN be assigned to the Storage Group for ease of use. Once the installation has completed, additional LUNs may be added to the Storage Group.

Booting from the SAN requires the use of a Unisphere/Navisphere Management station with the Unisphere/Navisphere Manager or NaviCLI. The stations must be separate from the boot server, but networked to the VNX series or CLARiiON storage system.
