Apparatus, system, and method for booting using an external disk through a virtual SCSI connection

摘要

An apparatus, system, and method are disclosed for booting a Logical Partition using an external storage device. The method creates a virtual SCSI device assigned to a first logical partition ("LPAR") of a first computer using a virtual I/O server by mapping a LUN of a storage volume to a SCSI ID. The storage volume is located external to the first computer and the first LPAR is configured to share one or more physical processors and one or more physical I/O devices of the first computer with a plurality of LPARs. The method receives a boot request to boot the first LPAR. The boot request identifies the storage volume as a boot device using the SCSI ID of the virtual SCSI device. The method retrieves boot data from the storage volume using a SCSI driver of the first LPAR and boots the first LPAR using the boot data.
