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.
