The system 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 volume data as if no
data migration were occurring.
Data migration applications
Data migration has the following characteristics and applications:
- Changes the MDisks to which the volume is allocated.
- Does not disrupt access to the volume data.
- Can be used when you are removing MDisks from a clustered system.
- Can move data to an MDisk that has appropriate performance for host requirements.
- Can move data from image mode volumes to MDisks when you
are adding a
system to an existing SAN infrastructure.
- Can migrate striped and sequential volumes to an image mode
volume.
