23 Boot-from-SAN considerations
The template attributes include the attributes to support Boot-from-SAN operations. Boot-from-SAN
functionality may run over iSCSI, FC, or FCoE connections. The Boot-from-SAN operations attributes include
the attributes for both initiators and targets.
Regardless of the protocol being used, the storage (target) hardware and software must be setup, configured,
and available on the network. It is beyond the scope of this document to address this topic, as these
procedures are usually vendor-specific.
Irrespective of the protocol, ensure the following actions for the storage (target) hardware and software:
• Setup
• Configuration
• Availability on the network
For a device to boot-from-SAN, its attributes need to be configured correctly. During the manual identity
assignment, the operator sets all the attributes to the appropriate values. During OME’s auto identity
assignment, OME uses the Virtual I/O pool associated with the Compute Pool to set applicable Initiator
identity attributes associated with Boot-from-SAN operations. If you need to change the Target attributes for
Boot-from-SAN operations (For example, if you need to use the different target), the operator has to make
those changes manually.
