zl5380(7)


zl5380 -- 5380 compatible SCSI host adaptor subsystem

Description

The zl5380 SCSI host adaptor driver provides a Storage Device Interface (SDI)-compliant interface to the Trantor T160 adaptor and the SCSI interface provided by the Media Vision Pro Audio Spectrum 16 adaptor. The driver enables SDI-compliant target drivers (sc01 and st01) to communicate on the SCSI bus with target controllers and logical units. This allows normal access to the SCSI devices connected to the Trantor T160 or Media Vision Pro Audio Spectrum 16 host adaptor using standard system interfaces and filesystems.

You can access the SCSI bus subsystem directly by using the driver's pass-through interface. This allows the user to issue sb control blocks directly to a SCSI target device. To find the appropriate pass-through device to use for a particular target device, the user should open(2) the character special file for the device in question and then issue the B_GETDEV ioctl (see ioctl(2)). The device value returned should then be used to create a character special file which, when opened, can be used for pass-through (SDI_SEND ioctl).

ioctl calls

zl5380 supports all of the SDI pass-through ioctl(2) commands documented on the sdi(7) manual page.

Notices

By default, interrupts are disabled on the Trantor T160 adaptor. The performance of the driver is improved by setting the interrupts on the card using jumpers.

Exercise caution when using the pass-through interface. You can interfere with normal system I/O and cause hangs if pass-through is used to an active device. Pass-through should be used only to a device that is otherwise quiescent.
