SAN Volume Controller allows
you to migrate data across MDisks without interfering with any host
applications that are simultaneously accessing or writing data.
During data migration, host applications can continue
to access and use VDisk data as if no data migration were occurring.
Data migration applications
SAN Volume Controller data
migration has the following characteristics and applications:
- Data migration changes the MDisks to which the VDisk is allocated.
- Data migration does not disrupt access to the VDisk data.
- Data migration can be used when removing MDisks from a cluster.
- Data migration can move data to an MDisk that has appropriate
performance for host requirements.
- Data migration can move data from image mode VDisks
to MDisks when adding SAN Volume Controller to
an existing SAN infrastructure.
- You can migrate striped and sequential VDisks to
an image mode VDisk.
