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 server or reset the server if power is already present, and disable
auto-boot in the OpenBoot environment.
See Obtaining the OpenBoot Prompt.
- Enter the OpenBoot environment.
- List the device paths on the server.
For example, the output from the command might include this line for a SPARC T7-1:
ok show-devs
...
/pci@301/pci@2/scsi@0
...
- Use the OpenBoot select command
to specify the controller where you want to create a hardware RAID
volume.
ok select /pci@301/pci@2/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 the previous step, you must
unselect the current controller.
ok unselect-dev
Now you can select a different controller, as described in the previous step. 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.
