Running a 'probe-scsi' at the obp can cause your system to hang unless you clear the CPU registers first - Here's how:
- Drop to the open boot prom
- Set the auto-boot? parameter to false:
- Reboot the system using reset-all:
- When the system stops at the ok prompt, you can safely probe:
ok} setenv auto-boot? false
ok} reset-all
ok} probe-scsi-all /pci@1f,0/pci@1,1/scsi@2 Target 0 Unit 0 Disk SEAGATE ST318203LSUN18G 034A Target 1 Unit 0 Disk HP 4.26GB F 80-1201
