If you're unable to create a logical drive in the Cisco Integrated Management Controller (CIMC), it could be due to several reasons. Here are steps to troubleshoot: Hardware Issue: Ensure all hardware components (disks, RAID controller, etc.) are in working condition. Firmware Update: Update the firmware of your server and RAID controller to the latest version. Disk Status: Check that the drives are not part of an existing array, are of the correct type and size, and are in 'Unconfigured Good' status. RAID Level: Confirm you have enough drives to support the RAID level you're trying to configure. Configuration Clear: If the above steps fail, clear the current RAID configuration (ensure you backup any data before doing this). Contact Support: If the issue persists, contact Cisco Support for further assistance.
