LSI got split up a few years back the SANS went to Netapp and the raids went to Broadcom you should be able to find the linux tools here https://www.broadcom.com/support/download-search/?pg=&pf=&pn=&pa=&po=&dk=MegaRAID+9266-4i

As for monitoring you have a few options, the megaraid cli is a nice tool, storage manager has a nice GUI if i remember correctly, and for remote monitoring look at the SMIS provider.
SMIS is an industry standard for storage monitoring that works very well, there are a number of tools and API's that support it too. the down side is the API isn't documented well for consumption by the general public I wrote some documentation about it for a perl implementation of a client some years back here https://github.com/prmarino1/Lib-CIM-Perl/blob/master/LCP::Query.md the documentation on how the queries  work  should work for any WBEM/CIM client and for any subset including SMIS and WMI.
when you get down to it CIM (the transport protocol for SMIS) is kind of like a sane version of SNMP where you can get just the raw data but you can also get the mib from the device you are querying.

LSI puts out an rpm, the one I've got laying around from an old install

Current version is either at your vendor's drivers page, or presumably
from LSI's own website.

I run the attached cronjob nightly to get an email report of the array's
