After installing the adapter and the c8xx driver and attaching the peripheral devices, verify that all of the components
are working by performing the following steps: To verify that the
adapter is correctly installed, issue the following command: ioscan -fnk The applicable lines 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 A6829-60101
ext_bus 0 0/0/10/0/1 c8xx CLAIMED INTERFACE SCSI C1010 Ultra160 Wide LVD A6829-60101
The third column shows the hardware path of the PCI device/function (shown
in bold in the above example,
for highlighting purposes). The A6829A supports two PCI devices/functions
(one per channel). In addition, since this is a dual channel HBA,
two lines are listed—one for channel A of the adapter (denoted
by a 0 as the last digit in the hardware path), and one
for channel B (denoted by a 1 as the last digit). In the same lines 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 A6829-60101
ext_bus 0 0/0/10/0/1 c8xx CLAIMED INTERFACE SCSI C1010 Ultra160 Wide LVD A6829-60101
If the adapter is not claimed, see “If
the A6829A Adapter is Not Claimed”“If the A6829A Adapter is Not Claimed” on
page 88. Still in the same lines of the
ioscan output, verify that the SCSI driver and adapter
information are displayed (they are 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 A6829-60101
ext_bus 0 0/0/10/0/1 c8xx CLAIMED INTERFACE SCSI C1010 Ultra160 Wide LVD A6829-60101
In this example, the SCSI driver information is c8xx (the 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. A6829-60101—The HBA’s HP part number.
In addition, in the ioscan output, the ctl lines show 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 Initiator
/dev/rscsi/c0t7d0
ctl 1 0/0/10/0/1.7.0 sctl CLAIMED DEVICE Initiator
/dev/rscsi/c1t7d0
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]).

operation. |
