Abstract:
A method for managing a cluster of nodes, said method comprising the steps of:coupling first and second nodes in said cluster; said first node recognizing said second node as an operational node in said cluster; subsequently, said second node being decoupled from said cluster; subsequently, said second node recoupling with said cluster; subsequently, said first node recognizing that said second node has been recoupled with said cluster; in response to the subsequent recognizing step, said first node diagnosing at least one characteristic of said second node relating to operational status of said second node; and subsequently, if said second node is operational, said second node verifying its configuration to said first node and then said first node sending a command to be executed by said second node for load balancing; and wherein said first and second nodes are both coupled to a same plurality of RAID storage controllers, and said command is a storage access command.
