If the A6829A Adapter is Not Claimed

If the A6829A Adapter is Not Claimed

If the A6829A 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, follow these steps:

Step 1. Confirm that the c8xx driver has not claimed the A6829A adapter, by issuing this command:

ioscan -f

The applicable lines (one for each channel of the HBA) in the ioscan output could look like this:

unknown	-1	0/0/10/0/0	UNCLAIMED	UNKNOWN	PCI	SCSI	(10000021)
unknown	-1	0/0/10/0/1	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” on page 74 or step 6 below.)

Step 2. Check to see if the c8xx driver is loaded in the kernel, by doing one of these two things:

•Use SAM, as follows:

1.Select the “Kernel Configuration” icon.

2.Select the “Drivers” icon.

3.On the “Kernel Configuration” screen, check to see if the c8xx driver is in the kernel.

•Issue this 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 A6829A adapter is still not claimed, go to step 4.
