esos 3.0.14_z H/W RAID error. MegaCli64 tool is not installed

[ivanco007]

Hi!
We use esos 3.0.14_z with SAS 9361-8i RAID card
but MegaCli64 tools doesn't install

health_chk.sh output:
"Checking hardware RAID logical drives...

Checking hardware RAID physical drives...

It appears the '/opt/sbin/MegaCli64' tool is not installed, or at least
is not executable. Skipping additional MegaRAID health checks...

Checking MD RAID arrays... "

Can anybody help with MegaCli64 or StorCLi installaition process?
Thanks a lot!

P.S. esos 4.x.x won't even boot???

Update

We install MegaCLi64 with raid_tools.py BUT

ERROR
No hardware RAID controllers were detect
Are the correct HW RAID CLI tools installed?

health_chk.sh output:
Checking hardware RAID logical drives...

Checking hardware RAID physical drives...

Starting additional MegaRAID health checks...
Number of adapters found: 1
Checking physical drives for media errors...
Checked 4 physical drive(s).
Checking enclosure(s) health/state...

Checking MD RAID arrays...

What that mean?
