If the A6828A Adapter is Not Claimed

If the A6828A adapter is not claimed (it shows as “UNCLAIMED” in the output from the ioscan command), the most likely reason is that you installed the c8xx driver but did not install the required patches.

To fix this problem, perform the following steps:

Confirm that the c8xx driver has not claimed the A6828A adapter, by issuing the following command:
ioscan -f
The applicable line in the ioscan output could look like this:
```
unknown -1  0/0/10/0/0          UNCLAIMED  UNKNOWN    PCI SCSI (10000021)
```
In the example above, the pieces of information that are abnormal—indicating an unclaimed adapter—are shown in bold, for highlighting purposes. (To see what “normal” output could look like, see “Verifying Installation” or step 6 below.)
Check to see if the c8xx driver is loaded in the kernel, by doing one of the following two things:
- Use SAM, as follows:
  Select the “Kernel Configuration” icon.
  Select the “Drivers” icon.
  On the “Kernel Configuration” screen, check to see if the c8xx driver is in the kernel.
- Issue the following command:
  what /stand/vmunix | grep scsi_c8xx.c
  Check to see if the c8xx driver is listed.
If the driver is in the kernel but the A6828A adapter is still not claimed, go to step 4.
If the driver is not in the kernel, go to step 3.
Load the c8xx driver into the kernel through SAM by performing the following steps:
1. Select the “Kernel Configuration” icon.
2. Select the “Drivers” icon.
3. In the “Kernel Configuration” screen, follow the normal steps for loading the driver into the kernel (and building a new kernel).
Note that you will need to reboot the system as part of these steps.
If the c8xx driver is in the kernel but the A6828A adapter is still not claimed, check the /var/adm/syslog.log file for errors like these:
```
Jan 11 16:08:00 svt38 vmunix: SCSI: SIOP RAM address out of range
Jan 11 16:12:05 svt38 vmunix: init of hardware not successful. id=10000021 and
my_isc=24
```
If you encounter such errors, you must install the patches required for the c8xx driver. You can find information on the patches you need to install in the following places: (1) the README file for the March 2002 (and later) HWE1100 patch bundle (for HP-UX 11.0), and (2) the March 2002 (and later) HP-UX 11i Release Notes (for HP-UX 11i).
Follow the normal procedure to install the required patches.
Note that you will need to reboot the system as part of these steps.
After the system reboots, verify that the adapter is now claimed, by issuing the following command:
ioscan -fnk
The applicable line in the ioscan output could look like this:
```
ext_bus 0 0/0/10/0/0 c8xx CLAIMED INTERFACE  SCSI C1010 Ultra160 Wide LVD A6828-60101
```
In the example above, the pieces of information that are normal—indicating a claimed adapter—are shown in bold, for highlighting purposes.
If the A6828A adapter is claimed, you have fixed the problem.
If the adapter is still not claimed, repeat steps 2 through 6, as needed.
