When
devices are accessible through a general-purpose SAN, a mechanism is needed to ensure that the
devices are accessed only by the storage system.
Use one of the following techniques to control the access to the
storage systems and devices:
- Switch zoning
- LUN-masking capability of the storage systems
Make logical units (LUs) or managed disks (MDisks) accessible to all ports on all the
nodes
for a clustered system.
Attention: Two systems are not prevented from accessing the same MDisks. However, if two
systems are configured so that they can detect the same MDisks, data corruption is likely to
occur.
