Dell 1950 server running Dell PERC 6 RAID controller, how can we monitor the RAID status under Centos 7 without checking it in boot status? Thanks.

How about PERC CLI? See here: http://www.dell.com/support/article/hu/hu/hubsdt1/sln283135/how-to-use-the-command-line-utility-on-your-dell-raid-controller-?lang=en

You have to download that from Dell, I am not a Dell customer so I can't help with that one. Or maybe it's on the DVD came with the server.– StoneJan 18, 2018 at 9:23
Stone's answer is correct, use the PERC CLI; his link gives good installation instructions, but currently doesn't lead to the RPM file. See https://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverid=52r3d for the latest version.
You can use "yum localinstall" instead of "rpm -i" on CentOS:
yum -y localinstall perccli-007.0127.0000.0000-1.noarch.rpm.
You have to run perccli64 as root. Example usage:
sudo /opt/MegaRAID/perccli/perccli64 -LDInfo -Lall -aALL

I have another perccli, so to get all possible info (about controller #0):
/opt/MegaRAID/perccli/perccli64 /c0/eall/sall show allMar 23, 2019 at 11:01
Tried perccli and megacli without success.
I managed to get status(health) of drives in a RAID environment using smartmontools.
What I didn't know was that they were hiding behind /dev/sg#
Example:
smartctl -a /dev/sg0 (1st physical disc)
smartctl -a /dev/sg1 (RAID1 virtual disc)
smartctl -a /dev/sg2 (2nd physical disc)
Not sure how to check RAID status, but helps a lot when checking for drive failure.
