I am searching for a long time tool that can runs as CLI on linux machine and identify which RAID configuration is defined on the disk or disks ( according to the list from lsblk )

the reason for that we cant showdown ( Production machines ) the linux machine and look on the RAID controler when OS id down

I am just cant understand why it is so difficult to capture the RAID conf when OS is up , must be somewhere tool that identify the RAID configuration

  • You already asked this question. I answered it. There is no tool that will tell you the firmware RAID controller's configuration all the time. – John Dec 9 '17 at 17:37

What's the make and model of your hardware?

At least some Fujitsu PRIMERGY servers use the megaraid_sas kernel module for their RAID controller. And Fujitsu provides a tool called ServerView RAID Manager which includes a command-line tool and a web GUI, both of which can both view and modify the RAID configuration. I think amCLI was the name of their command-line tool.

Dell has a MegaCli command-line tool for their LSI MegaRAID controllers.

You should check your hardware vendor's support pages for your specific OS + hardware model combination, and see if they offer any useful downloadables.

  • we have HP servers , do you know the tool that fit for HP? – yael Dec 9 '17 at 18:13
  • I found this - access.redhat.com/discussions/536883 – yael Dec 9 '17 at 18:27
  • Yes, HP (now HPe) has a similar (but not identical) tool for the purpose, named hpacucli. Looks like a lot of their downloads require a valid warranty or support registration now, so I cannot give you a direct link. – telcoM Dec 9 '17 at 19:24
