Ensure the following:
The disk drives have been properly installed on the server.
For more information, review the server Service Manual.
The host bus adapter (HBA) installed on the server is supported.
A list of supported HBAs is provided in the server Product Notes.
If the server is running a UNIX-based platform, you have root permission.
If the server is running the Oracle Solaris operating system, note the following:
On Oracle Solaris, raidconfig is not compatible with the raidctl CLI tool. raidconfig supports SAS2, but the raidctl tool does not.
For servers running Oracle Solaris, after hot-plugging any device, run the devfsadm -C command to reenumerate all of the system device nodes before running the raidconfig command.
Caution - Changing the RAID configuration erases all the data on the affected drives, including the OS. If you change the RAID configuration on a boot drive, you must reinstall the OS.
raidconfig create raid [--level level] [--stripe-size stripeSize] [--subarrays sizeOfRAIDcomponents] [--name volumeName] [--subdisk-size size] -disks disks
