Abstract
Intended is improvement in reliability of a disk array unit formed of a plurality of nodes at the time of start-up and stop. The disk array unit formed of a plurality of nodes, which includes a control unit which executes power source control of other node based on power source control information set at one of the nodes by inter-node communication executed through a common signal line which connects each node.
Claims27
A disk array unit formed of a plurality of nodes, comprising:
- a control unit which executes power source control of other node based on power source control information set at one of said nodes by inter-node communication executed through a common signal line which connects each said node.
A power source control method in a disk array unit formed of a plurality of nodes, comprising:
- a first step of sensing establishment of communication between respective said nodes by inter-node communication executed through a common signal line which connects each said node;
- and
- a second step of executing power source control of said extended node based on power source control information set at one of said nodes.
A computer readable medium storing a power source control program to be executed on a disk array unit formed of a plurality of nodes, wherein said power source control program causes a computer forming said disk array unit to execute:
- a first processing of sensing establishment of communication between respective said nodes by inter-node communication executed through a common signal line which connects each said node;
- and
- a second processing of executing power source control of said extended node based on power source control information set at one of said nodes.
