The ungleich hardware maintenance guide

This guide describes common operations on hardware we use.

APU Bios Update

APU Serial and bootloader configuration

  • Ensure that the bootloader has "console=ttyS0,115200" configured
  • Ensure that there is a getty running on serial
  • Use grub-bios as the bootloader
    • Install using grub-install /dev/sda

Updating the Perc H800 SAS controller

  • wget 'https://dl.dell.com/FOLDER03292738M/3/SAS-RAID_Firmware_XKF5X_LN_12.10.7-0001_A13.BIN?uid=4b8a2506-f4d4-46a9-ab19-3c2a5008a782&fn=SAS-RAID_Firmware_XKF5X_LN_12.10.7-0001_A13.BIN' -O SAS-RAID_Firmware_XKF5X_LN_12.10.7-0001_A13.BIN
  • chmod u+x SAS-RAID_Firmware_XKF5X_LN_12.10.7-0001_A13.BIN
  • ./SAS-RAID_Firmware_XKF5X_LN_12.10.7-0001_A13.BIN

HP servers disk management

Show all drives/controller overview:

hpacucli ctrl slot=0 pd all show

Add a disk as raid0:

hpacucli ctrl slot=0 create type=ld drives=1I:1:1 raid=0

Dell servers disk management

Listing all disks:

megacli -PDList -aALL

Adding disks:

megacli -CfgLdAdd -r0 [Enclosure Device ID:slot] -aX (X : host is 0. md-array is 1)

# Sample call, if enclosure and slot are KNOWN (aka not N/A)
megacli -CfgLdAdd -r0 [32:0] -a0

# Sample call, if enclosure is N/A
megacli -CfgLdAdd -r0 [:0] -a0

Remove cache of disks that are not in the server anymore:

megacli -DiscardPreservedCache -Lall -aAll

Remove foreign configurations on foreign disks

megacli -CfgForeign -Clear -aAll

Do both in many cases:

megacli -DiscardPreservedCache -Lall -aAll
megacli -CfgForeign -Clear -aAll
