Environment

• Broadcom SAS3108
• Broadcom SAS3516
• HCP G10
• HCP G11

Procedure

1. To generate the RAID controller log (ttylog) output:
   • MegaCli.exe -FwTermLog -Dsply -aALL (for Windows)
   • ./MegaCli64 -FwTermLog -Dsply -aALL (for Linux)
2. To generate a list with information about the RAID controllers, virtual disks and hard disks installed:
   • MegaCli.exe -PDList -aALL (for Windows)
   • ./MegaCli64 -PDList -aALL (for Linux)
3. To generate a list with information about existing RAID volumes and configurations:
   • MegaCli.exe -LDInfo -LALL -aALL (for Windows)
   • ./MegaCli64 -LDInfo -LALL -aALL (for Linux)
4. To generate a list with information about RAID controller settings:
   • MegaCli.exe -AdpAllInfo -aALL (for Windows)
   • ./MegaCli64 -AdpAllInfo -aALL (for Linux)
5. To generate a detailed list of the battery status of the RAID controller (state of charge, learning cycle, etc.):
   • MegaCli.exe -AdpBbuCmd -aALL (for Windows)
   • ./MegaCli64 -AdpBbuCmd -aALL (for Linux)
6. To create the RAID controller log (ttylog) with all information since very first controller initialization:
   • MegaCli.exe -AdpEventLog -IncludeDeleted -f filename.txt -aALL (for Windows)
   • ./MegaCli64 -AdpEventLog -IncludeDeleted -f filename.txt -aALL (for Linux)
