Abstract

The embodiment of the invention provides a VTL backup method and VTL nodes, and relates to the field of communication. The VTL backup method and the VTL nodes can improve usability of a VTL node link. The VTL backup method comprises the steps that when a fault port is detected, a cluster file system is visited to obtain a normal port in the VTL node where the fault port is located, the WWPN of the fault port and virtual device information running on session connection corresponding to the WWPN; then the WWPN of the fault port is drifted to the normal port; according to the WWPN drifted to the normal port, the session connection between the normal port and a backup server port is created; a virtual device below the fault port is allocated to the session connection, the session connection enables the virtual device below the fault port to be mounted to a backup server, and the backup server enables the virtual device to be operated through the session connection to carry out data backup.

Description

technical field

[0001] The present invention relates to the communication field, in particular to a VTL (Virtual tape library, virtual tape library) backup method and a VTL node. Background technique

[0002] When VTL is used for backup, its network architecture is as follows: figure 1 As shown, it includes: a backup server 11, a fiber optic switch 12, two paired VTL nodes A131, VTL nodes B132 and RAID14 (Redundant Array of Independent Disks, redundant array of independent disks). Several virtual tape libraries, virtual tape drives, and virtual tapes are created in the two VTL nodes.

[0003] The backup server 11 is physically connected to the VTL node A131 and the VTL node B132 respectively through the optical fiber switch 12, and the ports T1 and T2 of the VTL node A respectively correspond to a WWPN (World Wide Port Name, globally unique port name). If a virtual tape drive A is created on the VTL node A, then the VTL node A131 will allocate a session connection on a por...
