There are restrictions for sharing EMC VMAX systems
between a host and the system.
An EMC VMAX system can be shared between a host and the
system under the following conditions:
- When possible, avoid sharing target ports between the system and other hosts. If you cannot avoid this situation,
you must regularly check the combined I/O workload that is generated
by the system and the other hosts. The performance of either
the system or the hosts is affected if the workload exceeds
the target port capabilities.
- A single host must not be connected to both the system and an EMC VMAX because the multipathing drivers
(for example, subsystem device driver [SDD] and PowerPath) cannot
coexist.
- If the EMC VMAX is configured in such a way that other hosts cannot
access the LUs that are managed by the system, other hosts can be directly connected to an
EMC VMAX system at the same time as the system.
