Multiple Adapters

The HP NetRAID drivers and firmware will support up to six adapters, but your
particular model of HP Netserver may have fewer PCI slots available. Be sure to
check your system's PCI I/O slot availability and any slot restrictions before
purchasing another adapter.
If you will be configuring more than one adapter, make one photocopy of
Worksheets A and B for each adapter.

Boot Order

The RAID BIOS residing on the HP NetRAID-1M or 2M board will report the
first logical drive of each adapter to the Netserver system BIOS. The system
BIOS will then include these logical drives in its boot order selection list.
Sharing IRQs
The adapter can share IRQs. To determine the implications of IRQ sharing for
slot selection, refer to your system documentation and the NOS Installation
Guide in the HP Netserver Navigator CD-ROM.
Cable Management
Cable management is another factor to consider when choosing a slot for the
adapter. Try to avoid having cables block access to other I/O cards in the system.
!
Log the adapter's PCI slot on Worksheet A.

Channels

!
In this section you determine which physical devices will connect to each SCSI
channel of the adapter. Record the SCSI ID number and physical capacity of each
disk drive in the correct channel on Worksheet A. No two devices on a single
channel can have the same SCSI ID. SCSI ID 7 is reserved for the
HP NetRAID-1M or 2M adapter. For some HP Netservers and optional mass
storage enclosures, another SCSI ID is reserved for the processor managing the
mass storage cage or enclosure. Physical drives on different channels can be
assigned to the same array.
HP NetRAID-1M and 2M adapters support all HP hot-swap SCSI devices and
certain non-hot-swap SCSI devices, such as the Wide hard disk drives installed
in the HP Netserver E 60.
