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.
