IBM DS4000 FC manual Restore default settings, Raw NVRAM data, Scan fibre-channel devices

hard disk that is attached to the DS4000 FC 4Gbps PCI-X, select the attached fibre-channel hard disk from the system BIOS menu.

Note: The Selectable Boot Settings option for the DS4000 FC 4Gbps PCI-X applies to only fibre-channel hard disk drives.

Restore default settings

You can use the Restore Default Settings option to restore the DS4000 FC 4Gbps PCI-X default settings and NVRAM.

The default NVRAM settings are the adapter settings that were saved the last time an NVRAM update operation was run from the BIOS Update Utility program (option U or command line /U switch). If the BIOS Update Utility program has not been used to update the default NVRAM settings since the adapter was installed, the factory settings are loaded.

Note: After selecting Restore default settings, check the NVRAM settings (for example the host bus adapter and advanced adapter settings) against the values that are recommended in this document and in the device driver READMEs for the appropriate operating system.

Raw NVRAM data

You can use the Raw NVRAM Data option to display the adapter NVRAM contents in hexadecimal format. This is a troubleshooting tool. You cannot modify the data.

Scan fibre-channel devices

You can use the Scan Fibre Channel Devices option to scan the fibre-channel loop and list all the connected devices by loop ID. Information about each device is listed, for example, vendor name, product name, and revision. This information is useful when you are configuring your DS4000 FC 4Gbps PCI-X and attached devices.

Fibre-channel disk utility

Attention: When you perform a low-level format, it removes all data on the disk.

You can use the Fibre Channel Disk Utility option to scan the fiber-channel loop bus and list all the connected devices by loop ID. You can select a disk device and perform a low-level format or verify the disk media or data.

Loopback data test

You can use the Loopback Data Test option to verify the basic transmit and receive functions of the adapter. A fiber-channel loopback connector option must be installed into the optical interface connector on the DS4000 FC 4Gbps PCI-X before starting the test.

Select host adapter

You can use the Select Host PCI-X Adapter option to select, configure, or view a specific adapter if you have multiple adapters in your system.
