Access to the quorum disk is based on storage system I/O performance. Priority is given to the storage system that has a higher performance before the link failure. When the communication link fails, both storage systems attempt to access the quorum disk. If the system that first attempts to access the quorum disk is the non-priority storage system, a timer is started. If the priority system attempts to access the quorum disk within a predetermined time interval, the priority system locks the quorum disk and forms the cluster. If the priority system does not attempt to access the quorum disk within the predetermined time interval, the non-priority system locks the quorum disk and forms the cluster."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Disaster recovery for split storage cluster","description":"A method, computer program product and/or computer system assigns access to a quorum disk in a split-storage cluster environment when a communication link between storage systems fails.
