Soft-state structure DMA Transport structure Attaching an HBA driver Register mapping Interrupt specification Interrupt handling Create power manageable components Report attachment status Soft State Structure The driver should allocate the per-device-instance soft state structure, being careful to clean up properly if an error occurs. Views Read Edit View history. A proper disk controller only allows a disk to talk to the same bus. If the contents of either the name property or the compatible property match a driver on the system, then that driver is bound to the device node. To label a volume, perform the following steps.

The system first attempts to match the contents of the compatible property, if the compatible property exists, to a driver on the system. Mutex for use by the target driver. There are two possible values:.

Attaching disks to a HBA does not create a driver. Type type to select a drive type:.

Provides a history of the events the command experienced while in the transport layer. Pointer for the target device’s SCSI inquiry data.

The driver should further allocate and initialize a transport structure for this instance. It is commonly used to store a scs to a private target driver state structure. Pointer to private data maintained by the HBA driver when using cloning. Devices with generic device names are required to supply a compatible property.

For the Solaris OS to recognize a volume, it must be labeled with the format command. Please help improve this article if you can.

Market share for Q2 according to a proprietary report from Dell’Oro Group. Here is an example of a per-target scsi-options property definition to disable synchronous data transfer for target device Once you have edited the configuration file, reboot the host for the changes to take effect.

Code fragments presented subsequently in this chapter use these fields to describe practical HBA driver operations. Typically a device zcsilinked to the operating systemcontrols the host adapter itself. The ISP hardware manages command timeout directly and returns timed-out commands with the necessary status, ha the isp sample driver timeout handler checks active commands for timeout state only once every 60 seconds.

These data structures include: This entry point is not required, and if none is supplied, the framework will attempt hlm probe and attach all possible instances of the appropriate target drivers. This article may require cleanup to meet Wikipedia’s quality standards. Finally, the driver should report that this instance of the device is attached and return success. Some devices specify a generic device name as the value for the name property.

Then executing a boot hab return the following and no more on the scsi configuration, means the HD is not seen by Solaris: Note – If the file does not exist, create it using the format in the example below.

Target driver developers can also benefit from reading this chapter. Learn how and when to remove these template messages. See “Transport Structure Cloning Optional ” for more gm.

Per-Command Structure Gkm HBA driver will usually need to define a structure to maintain state for each command submitted by a target driver. To label a volume, perform the following steps.
