Adding a disk drive to a system to increase storage capacity. See “Adding a
Hot-Pluggable Disk Drive” on page 16.

Replacing a faulty disk drive while the system is running. See “Replacing a Faulty
Hot-Pluggable Disk Drive” on page 19. When you intend to replace a faulty drive,
prepare replacement disks ahead of time to simplify replacement later. Each
replacement disk should be formatted, labeled, and partitioned the same as the
disks to be replaced, and have file systems or other application specific
preparation performed.

Removing a drive from a system that no longer needs it. See “Removing a
Hot-Pluggable Disk Drive” on page 27.
Adding a Hot-Pluggable Disk Drive
This section contains information on how to configure your system when you add a
disk drive while the power is on and the operating system is running.
The way in which you add a disk drive depends on the application you are using.
Each application requires that you decide where to install the new disk drive, add
the drive, and then reconfigure the operating environment.
In all cases, you must select a slot, physically install the disk drive, and configure the
Solaris environment to recognize the drive. Then you must configure your
application to accept the new disk drive.
Selecting a Slot for the New Disk Drive
The system’s internal disk array can accommodate up to 20 low-profile UltraSCSI
disk drives. The basic system configuration includes support for one to four disk
drives connected to a four-slot backplane.
Note -
To support five to twelve internal disk drives, you must install an optional
8-bay storage expansion kit, which includes an eight-slot backplane, UltraSCSI PCI
controller card, and all necessary cabling. A second 8-bay storage expansion kit is
required to support any more than twelve internal disk drives. These kits may be
factory-installed when you purchase your system, or installed later as an upgrade.
Figure 3–1 shows the system’s 20 internal disk slots. Disk slots are numbered from 0
to 19. When adding a new disk drive to the system, you should install the drive in
the lowest available slot number.
