LifeKeeper for Linux offers shared storage kits tailored to your specific shared storage needs. Please refer to the comparison table below for the device nodes protected by each kit. If no kit is explicitly used, SCSI-2 reservation is performed for the Linux SCSI device (/dev/sdX device node).
Please note that the term “shared storage” on this page refers to storage that enables exclusive control via reservations using the SCSI protocol. For alternative storage methods such as NFS and VMDK, please refer to the NAS Recovery Kit Overview and Recovery Kit for VMDK as Shared Storage Overview, respectively.
