Logical volume management (LVM) migration is performed on a Linux host. It supports block devices that have been presented to the Linux host as logical devices. LVM migration may be performed from any Dell storage product or third-party storage system. LVM migration can be performed over iSCSI or Fibre Channel and is an included service with most standard Linux distributions.
Depending on the method of LVM migration that is used, host access to the block devices can continue while the migration transfer takes place. Once complete, the migration session can be cut over so that host access can resume on the volumes that are presented by the PowerStore system. At this point, the source storage resources may be decommissioned, or they may be kept if a rollback operation is required.
Since LVM migration is a host-based operation, supporting material for LVM migration is on the associated Linux distribution of the Linux host that is used for LVM migration.
