MAP 3145

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

The possible causes follow:

  • Device enclosure or adapter microcode levels are not up to date.
  • Unsupported type of device enclosure or device.
Consider removing power from the system before connecting and disconnecting cables or devices, as appropriate, to prevent hardware damage or erroneous diagnostic results.

Step 3145-1

Identify the adapter SAS port associated with the problem by examining the hardware error log. The hardware error log might be viewed as follows:
  1. Follow the steps in Examining the hardware error log and return here.
  2. Obtain the Resource field from the Detail Data / PROBLEM DATA section as illustrated in the following example: 
    Detail Data
PROBLEM DATA 
0000 0800 0004 FFFF 0000 0000 0000 0000 0000 0000 1910 00F0 0408 0100 0101 0000
          ^
          |
      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 were equal to 0004FFFF, port 04 on the adapter is used to attach the device or device enclosure, which is experiencing the problem.

Step 3145-2

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

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

Review the device enclosure cabling and correct the cabling as required. To see example device configurations with SAS cabling, see Planning for serial-attached SCSI cables.

Step 3145-3

Run diagnostics in system verification mode on the adapter to rediscover the devices and connections.
  1. Start Diagnostics and select Task Selection on the Function Selection display.
  2. Select Run Diagnostics.
  3. Select the adapter resource.
  4. Select System Verification.
Referring to the steps in Examining the hardware error log, did the error reoccur?
No
Go to Step 3145-4.
Yes
Contact your hardware service provider.

Step 3145-4

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