# yum install OpenIPMI (or use rpm to install OpenIPMI/OpenIPMI-libs rpms directly) On Dell SSD systems using ledctl and ledmon requires the ipmi drivers to be loaded. Ledctl can be used to identify an individual drive on a backplane, useful when determining which drive maps to which drive bay slot. Ledmon can be run as a daemon to constantly monitor the status of drives and Software RAID and set the drive LEDs appropriately. SLES11 SP2 however uses an older version of ledmon that must be updated in order to support Dell PCIE SSD devices. The latest ledmon package ships with RHEL6.3. Monitor Name, MRMonitor, MRMonitor, Adaptec Event Manager, Adaptec Event Manager Monitor Location, /opt/Broadcom/mrmonitor/bin/mrmonitord, C:Program Files (. According to the specification, there can be several states for drive LEDs: Ledmon uses the International Blinking Pattern Interpretation (IBPI) specification for displaying which state the drives are in. The activity LED is caused by drive activity, read or write. Normally drive backplane LEDs are controlled by a hardware RAID controller (PERC), but when using Software RAID on Linux (mdadm) for PCIE SSD, the ledmon daemon will monitor the status of the drive array and update the status of drive LEDs.ĭell systems use a three-LED status on their backplane. Ledmon and ledctl are two utilities for Linux that can be used to control LED status on drive backplanes.
