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.
