Question
The systems administrator received an alert that one of the servers went offline. The systems administrator logged on remotely to the machine using the IPMI connection and noticed the following message upon boot up: No logical volumes present. Press F1 to continue. Which of the following is the BEST step for the systems administrator to take to resolve the issue?
Options
- ACheck the array controller to see if the disks are visible.
- BVerify the array controller to determine if it is seen by the BIOS.
- CEnter the BIOS and enable the disk.
- DResume the server reboot by pressing F1.

Why each option
The error message 'No logical volumes present' during server boot indicates that the RAID controller cannot detect or present any configured logical volumes, requiring investigation of the physical disks and RAID array configuration.
The message 'No logical volumes present' directly points to an issue where the RAID controller is not able to detect or present any RAID arrays to the operating system. The most appropriate first troubleshooting step is to access the RAID controller's utility or BIOS to verify if the physical disks are visible and if the logical volumes are properly configured and healthy.
While the array controller must be seen by the BIOS, the specific error implies the controller is recognized but isn't presenting valid volumes, so checking its visibility isn't the most direct first step.
The BIOS does not typically 'enable' individual disks within a RAID array; the RAID controller itself manages the disk configuration and presents logical volumes.
Pressing F1 would only bypass the error message, likely leading to a 'No boot device found' message, without resolving the underlying problem of missing logical volumes.
