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 I

O operation) or Mass

Storage (for conventional non-I

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.
