Adaptec AHA-2950U2B - Ultra2 SCSI Driver

Using the SCBs in a straight forward manner would only allow the driver to handle as many concurrent transactions as there are physical SCBs.

Проект OpenNet: MAN cadp (FreeBSD и Linux)

To fully use the SCSI bus and the devices on it, requires much more concurrency. If you have problems at bootup, please make sure you aren't using this option.

There is no reliable way to autodetect this ordering. So, we default to the most common order, which is lowest to highest.

Then, in case your motherboard scans Adaptec AHA-2950U2B - Ultra2 SCSI highest to lowest, we have this option. If your BIOS finds the drives on controller A before controller B but the linux kernel finds your drives on controller B before A, then you should use this option.

As a result, timeouts and resets on those devices appear on the console. This violates the SCSI protocol and it causes the cadp driver to behave erroneously. Because this is difficult to guard against, you should disable tagged queuing for these targets.

Use the iostat --E command to determine if you have a Fujitsu MS disk. However, if you have such a configuration, add the following entry to the cadp.

This entry disables wide negotiation for the specified target. Also ensure that the upper 8 bits of the bus are properly terminated at both ends of the SCSI chain.

If you place a narrow device at the end of the chain, wide devices on the same chain will terminate the low byte, resulting in a illegal configuration. The scsi-options properties that are specified per target ID have the highest precedence, followed by scsi-options per device type.

Global scsi-options for all cadp instances per bus have the lowest precedence. You must reboot the system for the specified scsi options to take effect.

Driver Capabilities To enable certain features on the cadp driver, the target driver must set capabilities. The following capabilities can be queried and modified by the target driver: All other capabilities are query only.
