Prepare to Create a RAID Hardware Volume
(FCode-based RAID Utility)
Perform this procedure to be ready to create
a RAID volume using the FCode-based RAID utility. This procedure
also enables you to use other FCode-based RAID utility commands
on a specific controller.
- Perform the following procedure from an Xterm or an equivalent terminal window that supports
scrolling.
Note - OpenBoot commands and FCode-based commands produce large
amounts of detailed output. An Xterm or Gnome terminal window provides
scroll bar functionality, which helps you view such output.
- Either apply power to the system
or reset the system if power is already present, and disable auto-boot in
the OpenBoot environment.
See Obtain the OpenBoot Prompt Under Various Conditions.
- Enter the OpenBoot environment.
- List the device paths on the
server.
For example, the output from the command might include these
lines:
ok show-devs
...
/pci@300/pci@1/pci@0/pci@4/scsi@0
/pci@300/pci@1/pci@0/pci@4/scsi@0
...
- Use the OpenBoot select command
to specify the controller where you want to create a hardware RAID
volume.
ok select /pci@300/pci@1/pci@0/pci@4/scsi@0
Instead of using the entire device path for the controller,
you can use a preconfigured alias for a controller. For example:
ok select scsi_alias
where scsi_alias corresponds to a
preconfigured alias you had previously created for your path.
- If you decide to select a different
controller after performing Step 5,
you must unselect the current controller.
ok unselect-dev
Now you can select a different controller, as described in Step 5.
You can then run other FCode-based RAID commands that apply to the
selected controller.
- Continue to create a hardware
RAID volume on the selected controller.
