But which type of alert?, in case of performance alert you have option described by koopa79. But for health status you will need to configure Service processor alerts. And there is also remote support monitored by HPE.
In case of 4.x version of SP be careful (slow), not difficult but not so intuitive.
And there is another thing - try to configure access to Infosight (cloud based utility for long-term analysis and reporting).
https://infosight.hpe.comProblem of Infosight is that informations from this portal you will get after 1-2 days. It is mainly used for longterm monitoring and especially prediction and analysis of performance and capacity.
You only post special code to SSMC and wait for ca 24 hours.
I am not expert just admin of some 3PARs.
