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.
