Use this procedure to resolve the following problem: Unsupported
enclosure function detected (SRC xxxx4110).
The possible causes are:
- Device enclosure or adapter code levels are not up to date.
- Unsupported type of device enclosure or device. For example, this
error can occur if a SATA device, such as a DVD drive, is attached
to certain levels of a CCIN 57B4 adapter. The initial levels of the
CCIN 57B4 adapter did not support SATA devices. To determine whether
an adapter supports SATA devices, see PCIe2
SAS RAID card comparison or PCIe3 SAS RAID card comparison.
Considerations:
To prevent hardware damage or erroneous diagnostic
results, remove power from the system as appropriate before connecting
and disconnecting cables or devices.
- Identify the affected adapter and its port by examining
the product activity log. Perform the following steps:
- Access SST or DST.
- Access the product activity log and record address information.
- If a type D IPL was not performed to get to SST or DST:
- The log information is formatted. Access the product activity
log and display the SRC that sent you here. Press the F9 key for address
information. This is the adapter address. Then, press F12 to cancel
and return to the previous screen. Then press the F4 key to view
the additional information to record the formatted log information.
The Adapter Port field indicates the port on the adapter that is reporting
the problem. There may be more than one port listed because multiple
ports map to the same physical connector. For example, ports 0 through 3 map to the first physical connector, 4 through 7 map to the second physical connector, and so on.
The port numbers are labeled on the adapter tailstock.
- If a type D IPL was performed to get to DST:
- The log information is not formatted. Access the product activity
log and display the SRC that sent you here. The direct select address
(DSA) of the adapter is in the format BBBB-xxxx:
- BBBB
- Hexadecimal offsets 4C and 4D
- xxxx
- Not used
In order to interpret the hexadecimal information
to get device addresses, see Examples:
Obtaining additional information from hexadecimal reports. The Adapter Port field indicates
the port on the adapter reporting the problem. There might be more
than one port listed because multiple ports map to the same physical
connector. For example, ports 0 through 3 map to the first physical connector, 4 through 7 map to the second physical connector, and so on.
The port numbers are labeled on the adapter tailstock.
- Determine the location of the adapter that reported the problem.
Go to Addresses and find the following
items:
- The card slot that is identified by the direct select address
(DSA)
- The physical connector identified by the port number found on
the adapter tailstock
Have you determined the location of the adapter and its port?
- No:
- Ask your next level of support for assistance. This ends the procedure.
- Yes:
- Continue with the next step.
- Check for the latest PTFs for the device enclosure or adapter
and apply them. If you need assistance finding PTFs, contact your
next level of support. 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 for the device or device enclosure attached
to the identified adapter port. To see example device configurations
with SAS cabling, see Serial-attached
SCSI cable planning,
in the Site and hardware planning
information.
- Perform the following steps to cause the adapter to rediscover
the devices and connections:
Note: Performing this step
causes the system partition to temporarily hang. Wait until the system
bypasses the temporary hang.
- Use the logical resources IO debug option in Hardware Service
Manager to perform another IPL of the virtual I/O processor that is
associated with this adapter.
- Vary on any other resources attached to the virtual I/O processor.
Did the error recur?
- No:
- This ends the procedure.
- Yes:
- Contact your hardware service provider. This ends the procedure.
