MAP 3245

Use this MAP to resolve the following problem: Unsupported enclosure function detected (SRN nnnn-4110) for a PCIe2 or a PCIe3 controller

The possible causes follow:

Device enclosure or adapter microcode levels are not up to date.
The type of device enclosure or device is not supported.

For example, this error can occur if a SATA device, such as a DVD drive, is attached to a CCIN 57B4 adapter. The CCIN 57B4 adapter does not support SATA devices. To determine if an adapter supports SATA devices, see PCIe2 SAS RAID card comparison and PCIe3 SAS RAID card comparison.

Consider removing power from the system before connecting and disconnecting cables or devices, as appropriate, to prevent hardware damage or erroneous diagnostic results.

Step 3245-1

Identify the adapter SAS port that is associated with the problem by examining the hardware error log. The hardware error log can be viewed as follows:

Follow the steps in Examining the hardware error log and return here.
Obtain the Resource field from the Detail Data / PROBLEM DATA section as illustrated in the following example:
Detail Data PROBLEM DATA 0001 0800 1910 00F0 0408 0100 0101 0000 0150 003E 0000 0030 57B5 4100 0000 0001 0004 FFFF FFFF FFFF 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0004 AA98 ^ | Resource is 0004FFFF

Using the resource found in step 2, see SAS resource locations to understand how to identify the controller's port that the device, or device enclosure, is attached.

For example, if the resource is equal to 0004FFFF, port 04 on the adapter is used to attach the device or device enclosure that is experiencing the problem.

Step 3245-2

Ensure that the device enclosure or adapter microcode levels are up to date.

If unsupported device enclosures or devices are attached, either remove or replace them with supported device enclosures or devices.

Review the device enclosure cabling, and correct the cabling as required. To see examples of device configurations with SAS cabling, see Serial attached SCSI cable planning.

Step 3245-3

Run diagnostics in system verification mode on the adapter to rediscover the devices and connections.

Start Diagnostics and select Task Selection on the Function Selection display.
Select Run Diagnostics.
Select the adapter resource.
Select System Verification.

Referring to the steps in Examining the hardware error log, did the error reoccur?

No: Go to Step 3245-4.
Yes: Contact your hardware service provider.

Step 3245-4

When the problem is resolved, see the removal and replacement procedures topic for the system unit on which you are working and do the "Verifying the repair" procedure.
