Hot-Pluggability
Hot-pluggability refers to the ability to remove and replace a component
without interfering with system operation. There are three components in a
ProLiant Storage System /U system that are considered hot-pluggable:
■ Drives - Failed hot-pluggable drives in fault-tolerant configurations can
be replaced without interrupting system operation. The data on the
failed drive will be automatically restored on the replacement drive.
■ Fan array - If one of the cooling fans in the storage system should fail
(status indicator is amber), the entire fan array can be replaced without
interrupting system operation.
■ Power supply - In systems with the optional redundant power supply
installed, either power supply may be removed and replaced without
interrupting system operation.
See Chapter 4 for specific limitations when replacing hot-pluggable
components. It is important to understand that the hot-pluggability features
must also be supported by the operating system, and in the case of the drives,
the SCSI controller. See Table 1-2.

1-8 Introduction to the ProLiant Storage System /U
Hot-Pluggable Drives
The ProLiant Storage System /U supports these Compaq hot-pluggable drives:
■ 1.6-inch Fast SCSI-2
■ 1.6-inch Fast-Wide SCSI-2
■ 1.6-inch Wide-Ultra SCSI-3
■ 1.6-inch Wide-Ultra SCSI-3 10,000 RPM Drive
■ 1-inch Fast-SCSI-2
■ 1-inch Fast-Wide SCSI-2
■ 1-inch Wide-Ultra SCSI-3
ProLiant Storage System /U will accept both 1-inch and 1.6-inch standard
height drives. The drives may be of any storage capacity but must be mounted
on Compaq hot-pluggable drive trays.
In ProLiant Storage Systems U2 (dual bus) models, SCSI IDs are automatically
assigned according to the drive location, allowing 1-inch and 1.6-inch drives to
be easily intermixed. However, to make the maximum use of storage space,
use 1-inch drives for up to six drives per bus.
Maximum Storage
The maximum number of drives that may be installed in ProLiant Storage
System /U is shown in Table 1-1 below.
Drive Tray Height Model U1 Model U2

1-9 Introduction to the ProLiant Storage System /U
SCSI Controllers
ProLiant Storage System /U may be connected to any Fast-Wide SCSI-2 or
Wide-Ultra SCSI controller with appropriate external wide SCSI cables.
Supported Compaq SCSI controllers include:
■ 32-Bit Fast-Wide SCSI-2 Controller
■ Wide-Ultra SCSI-3 Controller
■ SMART-2 Array Controller Family
SCSI ID Assignments
Each device on a SCSI bus must have a unique identification number in the
range of 0 to 6. The SCSI ID determines the device priority when attempting to
use the SCSI bus. The highest priority, SCSI ID 7, is reserved for the
controller.
SCSI IDs are automatically assigned in the storage system according to the
drive bay used for each drive. The SCSI ID for each bay is indicated on the
front panel for both single and dual bus systems.
CAUTION:
bay set with a SCSI ID that is already used by another device in the server if
both devices are on the same SCSI bus.
IMPORTANT:
(within the server) or in an external storage system, but not both. A configuration
with both internal and external SCSI hard drives requires more than one SCSI bus.
Server lockups could occur if a hard drive is installed in a drive
All SCSI hard drives on the same SCSI bus must be either internal

1-14 Introduction to the ProLiant Storage System /U
System Power
The system power in the ProLiant Storage System /U does not completely shut
off with the power switch. The two positions of the front panel power switch
should be considered as ON and STANDBY, rather than ON and OFF. The
STANDBY position removes power from most of the electronics and the drives
but portions of the power supply and some internal circuitry remain active.
To completely remove all power from the system, you must disconnect the
power cord from the storage system. In systems with multiple power supplies,
you must disconnect all the power cords to completely remove power from the
system.
WARNING:
equipment, disconnect power from the storage system by unplugging all
power cords from either the electrical outlet or the storage system.

1-15 Introduction to the ProLiant Storage System /U
Options
The following options are available for your ProLiant Storage System /U and
may be obtained from your local Compaq Reseller or Authorized Compaq
Service Provider.
Redundant Power Supply Option
ProLiant Storage System /U has provisions for adding a second power supply
that acts as a redundant supply when installed. The Redundant Power Supply is
identical to the primary supply and when installed, shares the electrical load
equally. If either supply should fail or be removed, the other will take over the
full load without interruption. Hot-pluggability permits replacing the failed
supply without bringing the system down.
The Redundant Power Supply can be installed by the user at any time by
simply plugging it in to the storage system. No tools are needed and there is no
need to bring the system down. See Chapter 5, “Installing Options” for more
information on installing and using this option.
Recovery Server Option
Recovery Server refers to a fault-tolerant technique where two independent
servers have access to the same stored data. Both servers are connected to
separate Wide-Ultra SCSI-3 ports on the storage system, but only one port has
access to the internal SCSI bus at a time. If the primary server should fail, the
Recovery Server option will automatically switch the storage system internal
SCSI bus connection to the secondary server. The secondary server will then
take over all functions of the system without loss of data. Both Online and
Backup recovery techniques are supported and all hardware, software,
instructions, and cabling are included in the kit. The Recovery Server Option
can only be used in ProLiant Storage System U1 (single bus) models.
The Recovery Server Option can be installed by the user by simply replacing
the standard I/O Board with the Recovery Server I/O Board. No tools are
required and there is no need to access internal cabling or circuitry. See
Chapter 5, “Installing Options” for more information on installing and using
this option.

1-16 Introduction to the ProLiant Storage System /U
Dual Bus Conversion
The Dual Bus Conversion option is offered for customers who find that their
Model U1 storage system now requires two SCSI buses. Dual Bus refers to
dividing the total storage space in the ProLiant Storage System Model U1 into
two separate storage areas, each with its own SCSI bus. This may be used:
■ as part of a fault-tolerant configuration (controller duplexing).
■ to make maximum use of the available storage space with up to
12 drives instead of 7 with a single SCSI bus.
■ as separate storage areas for two servers.
This option effectively converts the ProLiant Storage System Model U1 into a
Model U2. The available storage space is split into two Wide-Ultra SCSI-3
buses with four 1.6-inch drives or six 1-inch drives on each bus. Each bus is
totally independent and requires a separate Fast-Wide SCSI-2 or Wide-Ultra
SCSI-3 controller and cable. Dual Bus Conversion option cannot be used with
the Recovery Server option.
The Dual Bus Option can be installed by the user by replacing the Single Bus
I/O Board with the Dual Bus I/O Board and replacing the Single Bus drive cage
with a Dual Bus drive cage. See Chapter 5, “Installing Options” for more
information on installing and using this option.

1-17 Introduction to the ProLiant Storage System /U
Single Bus Conversion
The Single Bus Conversion option is offered for customers who find that they
no longer require two SCSI buses and want to convert it to a Model U1 single
bus system. This option provides the ProLiant Storage System Model U2 with
a single Wide-Ultra SCSI-3 bus that supports up to seven 1.6-inch or 1-inch
drives, effectively converting the unit to a Model U1. This may be used:
■ when the storage system is no longer part of a duplexed drive array.
■ when the storage space is no longer shared between two servers.
■ to make maximum use of the available storage space with a single
SCSI bus.
The Single Bus Option can be installed by the user by replacing the Dual Bus
I/O Board with the Single Bus I/O Board and replacing the Dual Bus drive cage
with a Single Bus drive cage. See Chapter 5, “Installing Options” for more
information on installing and using this option.
