Chapter 4 HP NetRAID Express Tools ◊ For optimal performance of RAID 5 logical drives, use separate adapters to control arrays with three physical drives and arrays with four or more physical drives. • Change Disk Geometry: Changes the layout of logical drives presented to the NOS. The default setting is 8 GB, and the alternative is 2 GB. Different operating systems use different disk geometries. Your NOS documentation may indicate the disk geometry it uses. NOTE Changing the disk geometry setting only changes the geometry of logical drives created after the change. It does not change the geometry of existing logical drives. • Disk Spin-Up Timings: Sets the method and timing for spinning up the hard disk drives in the HP NetServer. The default setting is Automatic. • Cache Flush Timings: Sets the cache flush interval to once every 2, 4, 6, 8, or 10 seconds. The default setting is 4 seconds. • View/Update Rebuild Rate: View or change the Rebuild Rate for the adapter. • Diagnostics: The hardware diagnostic tool performs the following hardware tests: ◊ On-board memory test ◊ NVRAM test ◊ Parity check ◊ DMA test ◊ Timer test ◊ Interrupt test ◊ Hardware register test • Adapter Type: Displays the adapter type: HP NetRAID-1Si, HP NetRAID-3Si, or integrated HP NetRAID. • Emulation: Sets PCI class code to I2O (for I2O operation) or Mass Storage (for conventional non-I2O mass storage). The default setting is Mass Storage. • Autorebuild: Enables or disables the Autorebuild parameter. For complete information, see "Rebuilding Data" in Chapter 5 in this guide. 80

For optimal performance of RAID 5 logical drives, use separate
adapters to control arrays with three physical drives and arrays with
four or more physical drives.
•
Change Disk Geometry
: Changes the layout of logical drives presented to
the NOS. The default setting is 8 GB, and the alternative is 2 GB. Different
operating systems use different disk geometries. Your NOS documentation
may indicate the disk geometry it uses.
NOTE
Changing the disk geometry setting only changes the geometry
of logical drives created after the change. It does not change

: Sets the method and timing for spinning up the
hard disk drives in the HP NetServer. The default setting is Automatic.
•
Cache Flush Timings
: Sets the cache flush interval to once every 2, 4, 6,
8, or 10 seconds. The default setting is 4 seconds.
•
View/Update Rebuild Rate
: View or change the Rebuild Rate for the
adapter.
•
Diagnostics
: The hardware diagnostic tool performs the following
hardware tests:
◊
On-board memory test
◊
NVRAM test
◊
Parity check
◊
DMA test
◊
Timer test
◊
Interrupt test
◊
Hardware register test
•
Adapter Type
: Displays the adapter type: HP NetRAID-1Si,
HP NetRAID-3Si, or integrated HP NetRAID.
•
Emulation
: Sets PCI class code to
I2O
(for I
2
O operation) or
Mass
Storage
(for conventional non-I
2
O mass storage). The default setting is
Mass Storage.
•
Autorebuild
: Enables or disables the Autorebuild parameter. For complete
information, see "Rebuilding Data" in Chapter 5 in this guide.
