B Boot-from-SAN Considerations
The attributes for a template include attributes to support Boot-from-SAN operations. Boot-from-SAN
functionality may run over iSCSI, FC, or FCoE connections. Attributes for Boot-from-SAN operations
include 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.
In order for a device to be able to boot-from-SAN, its attributes must be correctly configured. When using
manual identity assignment, the operator is responsible for setting all attributes to appropriate values.
When using OME’s auto identity assignment, OME uses the Virtual IO Pool associated with a Compute
Pool to set applicable Initiator identity attributes associated with Boot-from-SAN operations. If Target
attributes for Boot-from-SAN operations need to be changed (e.g., to use a different target), the operator
has to make those changes manually.
