Adding hard disks
If the capacity of the root disk is insufficient or you want to
reduce an I/O bottleneck on a disk, you may need to
install additional hard disks on your system. See
``Supported hard disk configurations''.
If you have multiple hard disks in your system,
you can manage your data storage more effectively by configuring
them as virtual disks. See
``About virtual disks'' in the System Administration Guide
for details.
