A Linux administrator has physically added a new RAID adapter to a system. Which of the following commands should the Linux administrator run to confirm that the device has been recognized? (Select TWO).
The following commands can help you confirm that the new RAID adapter has been recognized by the Linux system:
dmesg: This command displays the kernel messages, which can show the information about the newly detected hardware device. You can usedmesg | grep -i raidto filter the output for RAID-related messages.
The other commands are not relevant for this purpose. For example:
rmmod: This command removes a module from the Linux kernel, which is not useful for detecting a new device.
ls -l /etc: This command lists the files and directories in the /etc directory, which is not related to hardware devices.
pvdisplay: This command displays the attributes of physical volumes, which are part of the logical volume management (LVM) system, not the RAID system.
rmdir /dev: This command removes an empty directory, which is not helpful for detecting a new device. Moreover, /dev is a special directory that contains device files, and should not be removed.
