2.For more detailed information on the installed A7173A adapters, including verification of devices that have been connected to the A7173A adapter(s), use the mptconfig <dev file> command for each channel of each A7173A adapter. Use the device files displayed in the ioscan -fnkd mpt output. For example:

# mptconfig /dev/mpt8

NOTE: The In Use Device column only displays on systems running HP-UX 11i v3.

NOTE: When the system boots after installation, the insf command creates the proper device files for the “ctl” interfaces (which would include the A7173A adapter) as well as the SCSI devices attached to the A7173A adapter. Sometimes, however, the insf command does not create all of the device files that are needed. For example, this happens when you attach SCSI disks to the adapter after the system boots, but the adapter is already installed in the system.

If you see a SCSI device listed in the ioscan output, but there is no device file in the second line of the ioscsan output for that device, the device file is missing. To solve this problem, use the insf -ecommand, which will create all of the device files.

For more information about the ioscan command, see the ioscan(1M) man page.

For more information about the insf command, see the insf(1M) man page.

See your system documentation for information about verifying system operation.

Adding Multi-Initiator Support

The A7173A adapter supports multi-initiator configurations. In a multi-initiator configuration, multiple SCSI host bus adapters are connected to the same SCSI bus. See “About SCSI IDs” (page 24), for details on setting SCSI IDs in a multi-initiator configuration.
