2.4 Expanding the Server Unit
To add a fifth disk drive to the PRIMEPOWER200 Pedestal Server, the optional Disk Expansion Unit must be
installed.
The following settings should be made after the Disk Expansion Unit has been installed:
1 From the ok prompt execute the show-scsi command to get the path name of the UltraSCSI card and its PCI
slot.
The following example shows an UltraSCSI card installed in PCI slot#6.
ok show-scsi
PCI#6 : /pci@16,4000/scsi@5,1
PCI#6 : /pci@16,4000/scsi@5
SCSI#0: /pci@17,4000/scsi@3
ok
2 From the ok prompt set led-control-1 to correspond to the PCI slot number with the setenv command.
The following example shows an UltraSCSI card connected to SCSI connector #1 of the UltraSCSI card in
PCI slot#6.
ok setenv led-control-1 /pci@17,4000/scsi@5
Hot-swapping hard disk drives
CAUTION
Data Destruction
Data may be lost if hot-swapping of hard disk drives is not performed correctly.
Contact the service engineer if a hard disk drive must be hot-swapped.
IMPORTANT
To utilize the hot-swapping functions of the hard disk drive, use the option software (SynfinityDISK) to
perform mirroring.
Hard disk drives installed on the PRIMEPOWER200 Pedestal Server are hot-swappable. To enable hot-swapping,
use the tools (machine administration) contained in the "Enhanced Support Facility" to perform hot-swapping
while monitoring the state of the ACTIVE and FAULT LEDs. For details on how to swap hard disk drives, refer to
the "Machine Administration Instructions" included with the "Enhanced Support Facility".
