PowerStore appliances are independent of each other but are managed and maintained under a single cluster. In the modern data center, administrators must be quick and agile to support mission-critical applications. PowerStore data migration allows end users to easily move volumes, volume groups, and VMware virtual volumes from one appliance in the cluster to another, without disrupting host I/O. When you migrate a volume or volume group, all associated snapshots and thin clones are also migrated simultaneously with the underlying storage resource.
Note: To perform a rescan at the beginning of a migration (recommended), use rescan-scsi-bus.sh for a Linux host or the equivalent for a UNIX or Microsoft Windows operating system.
AppSync is unaware and unaffected by a PowerStore migration. We recommend planning the migration to occur when a service plan or workflow repurposing is not in progress. Users can also use the maintenance mode functionality in AppSync to prevent workflows from running. After the migration is complete, rediscover the PowerStore appliances in AppSync to update the records. All data will remain intact and the associated service plans and repurposing workflows will work normally.
