Dell H710P RAID card is equivalent to LSI MegaRAID SAS 9266-8i, so if you want to use the MegaCLI tool to manage the card, go to the LSI webpage:

Dell:

“Management Software and Tools” tag and download the MegaCLI for Linux. I am using CentOS 6.x. Inside of the zip file, there is a RPM that works!

To show all cards in your box:

/opt/MegaRAID/MegaCli/MegaCli64 AdpAllInfo -aALL

PS: Check check!

$ /opt/MegaRAID/MegaCli/MegaCli64 -LDInfo -LALL -aALL | grep State

State: Optimal

Good Luck!
