After installing the adapter and the c8xx driver and attaching the peripheral devices, verify that all the components are working by performing the following steps:

  1. To verify that the adapter is correctly installed, issue the following command:

    ioscan -fnk

    The applicable line in the ioscan output can have the following form:

    ext_bus 0 0/0/10/0/0 c8xx CLAIMED INTERFACE  SCSI C1010 Ultra160 Wide LVD A6828-60101

    The third column shows the hardware path of the PCI device/function (shown in bold in the above example, for highlighting purposes). The A6828A supports one PCI device/function (because it has only one channel). In addition, since this is a single channel HBA, one line is listed for channel A of the adapter (denoted by a 0 as the last digit in the hardware path).

  2. In the same line of the ioscan output, verify that the adapter is claimed by the SCSI c8xx driver by looking at the fifth column of information (shown in bold in the example below, for highlighting purposes).

    ext_bus 0 0/0/10/0/0 c8xx CLAIMED INTERFACE  SCSI C1010 Ultra160 Wide LVD A6828-60101

    If the adapter is not claimed, see “If the A6828A Adapter is Not Claimed”.

  3. In the same line of the ioscan output, verify that the SCSI driver and adapter information are displayed (shown in bold in the example below, for highlighting purposes).

    ext_bus 0 0/0/10/0/0 c8xx CLAIMED INTERFACE  SCSI C1010 Ultra160 Wide LVD A6828-60101

    In this example, the SCSI driver information is c8xx (name of the driver), and the adapter information is as follows:

    • SCSI C1010—The type of HBA ( SCSI) and the type of Ultra160 controller ( C1010).

    • Ultra160—The HBA’s maximum data transfer rate. This can be Ultra160, Ultra2, Ultra, Fast, or Async. You should keep the following in mind:

      • This is not the actual transfer rate, but the maximum transfer rate set for the HBA.

      • This is either the firmware default or the rate set through the BCH menus, unless you attach an SE device, which causes the entire bus to change to a transfer rate of Ultra (see “Performance Tuning”).

    • Wide—The HBA’s bus width. This can be Wide or Narrow.

    • LVD—The HBA’s bus type. This can be LVD or Single-Ended. If no bus type is shown, then the SCSI channel is disabled.

    • A6828-60101—The HBA’s HP part number.

  4. In addition, in the ioscan output, the ctl line shows the adapter’s SCSI ID in its hardware path (shown in bold in the example below, for highlighting purposes).

    ctl     0 0/0/10/0/0.7.0  sctl  CLAIMED   DEVICE     
                             /dev/rscsi/c0t7d0
  5. Verify that the devices you attached to the adapter are present in the ioscan output. For example, a partial list may look like this:

    disk   10 0/0/1/0/1.0.0  sdisk  CLAIMED   DEVICE     SEAGATE ST39103LC
                             /dev/dsk/c1t0d0  /dev/rdsk/c1t0d0
    disk   11 0/0/1/0/1.2.0  sdisk  CLAIMED   DEVICE     SEAGATE ST39103LC
                             /dev/dsk/c1t2d0  /dev/rdsk/c1t2d0
    disk   45 0/2/1/0/1.8.0  sdisk  CLAIMED   DEVICE     HP 18.2GST318404LC
                             /dev/dsk/c9t8d0  /dev/rdsk/c9t8d0
    disk   46 0/2/1/0/1.10.0 sdisk  CLAIMED   DEVICE     HP 18.2GST318404LC
                             /dev/dsk/c9t10d0 /dev/rdsk/c9t10d0

    The second line under each disk line shows the disk’s device files (/dev/... [shown in bold in the example above, for highlighting purposes]).

TIP: When the system boots after installation, the insf command creates the proper device files for the “ctl” interfaces (which are usually adapters) and the SCSI devices attached to the A6828A adapter. Sometimes, though, it does not create all of the needed device files.

One situation when this happens is when you attach SCSI disks to the adapter after the system boots and the adapter is already installed in the system.

In the ioscan output, if you see a SCSI device listed without the second line, that means you are missing that device’s device files. To fix the problem, issue the insf -e command, which creates all of the device files.

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

Refer to your system documentation for information on verifying system operation.
