14.2.4 Preparation Before Hardware RAID Operation


14.2.4 Preparation Before Hardware RAID Operation
Use the FCode utility to prepare for hardware RAID operation. Perform this work from xterm or an equivalent terminal that supports scrolling.
Operation Procedure
  1. Power on the system.
    If powered on already, reboot the system and disable auto boot in OpenBoot PROM.
  2. Confirm that the ok prompt is displayed.
  3. Execute the show-devs command to display a list of the server device paths.
  1. The following shows an example of the SPARC M10.
{0} ok show-devs
    .
    .
/pci@8000/pci@4/pci@0/pci@0/scsi@0
/pci@8000/pci@4/pci@0/pci@0/scsi@0/disk
/pci@8000/pci@4/pci@0/pci@0/scsi@0/tape
    .
    .
{0} ok
  1. Execute the select command to select the controller for creating a hardware RAID volume.
    For details on the relationship between device paths and internal HDD slot locations, see "Appendix A  Lists of SPARC M12/M10 System Device Paths."
Note - After executing the select command, you need to execute the unselect-dev command. After the procedure is finished, execute the unselect-dev command according to the directions in 14.2.5 or 14.2.6.
{0} ok select /pci@8000/pci@4/pci@0/pci@0/scsi@0
{0} ok
  1. Execute the .properties command to check the SAS address of the internal SAS controller.
{0} ok .properties
assigned-addresses 81030010 00000000 00000000 00000000 00000100
83030014 00000001 00000000 00000000 00010000

{0} ok 
Note - The output result of the .properties command is information that is needed for maintenance of the RAID volume. Be sure to make a note of this information.
  1. Execute the show-children command to display the SAS addresses of the connected drives.
{0} ok show-children
