Optional LUN Masking: No Report LUN

Interception

When a host (Linux or Windows) issues a SCSI report LUNs, the chassis filters the

response based on what is in the Oracle Fabric Interconnect database. If LUN

masking changes in an array and a host issues a report LUNs, the new LUN will not

be available to the host until a set vhba rescan command is run on the Oracle

Fabric Interconnect. In some cases, this approach goes against customer expectations

and breaks the existing model.

Use the -no-lun-masking feature to disable the LUN masking so that if you

choose to do LUN masking on arrays, rescans on the Oracle Fabric Interconnect are

not required. Specifically the -no-lun-masking feature disables the “report luns”

interception and allows all new LUN/target information to pass through directly to

SCSI. When SCSI issues the report luns command, the request will pass through

the Oracle Fabric Interconnect’s IOP and discover the disk array’s new LUN/target

information.

When a vHBA is created, LUN masking is enabled by default. An administrator

must use –no-lun-masking to disable it. The –no-lun-masking flag can be

specified only during the creation of a vHBA and cannot be changed throughout the

lifetime of this vHBA. After specifying this flag while creating a vHBA, the CLI will

also prevent you from assigning any LUN mask to this vHBA.

Note – No Report LUN Interception is the default when a vHBA is created.
