Abstract

The invention discloses an iSCSI (Internet Small Computer System Interface) service setting method, which comprises the following steps of: binding a target volume with an initiator, and writing the target volume and the initiator into a storage cluster; obtaining attribute information of all active nodes in the storage cluster, and sorting the number of lun corresponding to the active nodes according to the information to obtain a target list; based on the principle of uniform distribution of the number of lun, distributing the storage nodes to be set by the user on the active nodes of all rack cabinets according to the target list to obtain screening nodes; when the initiator logs in the screening node, mapping the target volume to the lun of the target corresponding to the screening node; and selecting a target node in the storage cluster, and configuring a virtual IP and an iqn which are the same as those of the screening node for the target node, so that when the screening node fails, the initiator uses the target node to access the target volume. Through the method, high availability of the iSCSI service in the storage cluster can be ensured.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a method, apparatus, device and medium for setting an iSCSI service. Background technique [0002] iSCSI (Internet Small Computer System Interface, Internet Small Computer System Interface) is a new storage technology, which combines the existing SCSI interface with Ethernet technology, so that the server can use IP (Internet Protocol, Internet Protocol) ) network storage devices exchange data with each other. The iSCSI service is based on the client / server model, and its main function is to encapsulate and transmit a large amount of data between the host system initiator and the storage device target on the TCP / IP network. However, in the prior art, there is no way to ensure the high availability of the iSCSI service in the storage cluster, and this problem needs to be solved by those skilled in the art. SUMMARY OF THE INVENTION [0003] In view of this, the p...
