We need a second machine, e.g. tethys

• burn image /project/dell_proje2850/Firmware_Updates/CD18FUP.iso on CD
  • further information in /project/dell_2850/Firmware_Updates/00README.sw
• downtime tethys, shutdown tethys, take out both disks
• put the disk with errors (select timeout) from machine with degraded raid into tethys slot 0
• boot tethys from CD, this makes automatically the firmware upgrade
  • comment: machine stops in BIOS, multiple ENTERs necessary
• put back the disk into the original machine again, the rebuild should start
  • check with /usr/sbin/dellmgr if the rebuild is running
