Abstract
When a failure occurs in an LPAR on a physical computer under an SAN environment, a destination LPAR is set in another physical computer to enable migrating of the LPAR and setting change of a security function on the RAID apparatus side is not necessary. When a failure occurs in an LPAR generated on a physical computer under an SAN environment, configuration information including a unique ID (WWN) of the LPAR where the failure occurs is read, a destination LPAR is generated on another physical computer, and the read configuration information of the LPAR is set to the destination LPAR, thereby enabling migrating of the LPAR when the failure occurs, under the control of a management server.
Claims14
A virtual computer system comprising a plurality of physical computers including first and second physical computers and a management apparatus that is connected to the plurality of physical computers via a network to manage the physical computers and logical partitions, and allows OSs to operate by generating the logical partitions on the physical computers,
- wherein the first physical computer includes:
- failure detection means for detecting that a failure occurs in the first physical computer or a first logical partition formed in the first physical computer;
- and
- first management means for managing hardware configuration information of the first physical computer and unique configuration information assigned to the first logical partition,
- the management apparatus includes:
- means for accepting notification of the failure occurrence from the failure detection means to receive the hardware configuration information and the unique configuration information from the first management means;
- and
- means for determining the substitute second physical computer to transmit the hardware configuration information and the unique configuration information to the second physical computer, and
- the second physical computer includes:
- means for receiving the hardware configuration information and the unique configuration information transmitted from the management apparatus;
- means for determining whether or not a second logical partition can be generated on the second physical computer on the basis of the hardware configuration information and the unique configuration information;
- and
- means for generating the second logical partition on the basis of the unique configuration information when the determination means determines that the second logical partition can be generated.
A control method of migrating logical partitions in a virtual computer system having a plurality of physical computers including first and second physical computers and a management apparatus that is connected to the plurality of physical computers via a network to manage the physical computers and the logical partitions, and allows OSs to operate by generating the logical partitions on the physical computers, the method comprising:
- in the first physical computer detecting that a failure occurs in the first physical computer or a first logical partition formed in the first physical computer;
- in the first physical computer managing hardware configuration information of the first physical computer and unique configuration information assigned to the first logical partition;
- in the management apparatus accepting notification of the failure occurrence from failure detection means to receive the hardware configuration information and the unique configuration information transmitted from the first physical computer;
- in the management apparatus determining the substitute second physical computer to transmit the hardware configuration information and the unique configuration information to the second physical computer;
- in the second physical computer receiving the hardware configuration information and the unique configuration information transmitted from the management apparatus;
- in the second physical computer determining whether or not a second logical partition can be generated on the second physical computer on the basis of the hardware configuration information and the unique configuration information;
- and
- generating the second logical partition on the basis of the unique configuration information when it is determined in the determination step that the second logical partition can be generated.
A control method of a virtual computer system having a plurality of physical computers, hypervisors that generate and control a plurality of LPARs in the respective physical computers, and a management apparatus that manages the plurality of physical computers and the respective LPARs on the physical computers,
- wherein each LPAR has a logical fibre channel port, and a software image including an operating system of each LPAR is booted from a storage area network by using a unique ID assigned to the logical fibre channel port,
- the hypervisor of each physical computer notifies, when detecting failure occurrence in any one of the plurality of LPARs under the control of the hypervisor, the management apparatus of the failure occurrence, the management apparatus instructs to generate, when receiving configuration information including the unique ID of the LPAR where the failure occurs from the hypervisor that detects the failure occurrence, a new LPAR by transmitting the configuration information including the unique ID of the LPAR where the failure occurs to any one of the hypervisors of the physical computers, and the hypervisor which receives the configuration information including the unique ID of the LPAR where the failure occurs generates a new LPAR with the same configuration information as the received one.
