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
Logical units (LUs) or managed disks (MDisks) should be made 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.
