Use this procedure to verify that a PCIe storage enclosure
is functioning and is recognized by the system.
Prerequisite: To use this procedure,
the PCIe storage enclosure must have power, must be connected to the
system, and the system must be powered on.
- Choose from the following options:
- If your system is managed by an Hardware Management Console (HMC), continue with step 2.
- If your system is not managed by an HMC, see Verifying the installed part.
When you are finished, continue with step 4.
- If your system is managed by an HMC, complete the following
steps:
- From the navigation area, expand Systems Management.
- Click Servers.
- From the content area, select the system with which you want to
work.
- Click .
- Click the I/O tab.
- Verify that the system recognizes the storage controllers
in the PCIe storage enclosure by completing the following steps:
- Scan the Slot column values to identify
the entries that correspond to the connections to the PCIe storage
enclosure. The following tips can be helpful in identifying these
entries:
- When an entry corresponds to a PCIe storage enclosure connection,
the Slot column contains an identifier that resembles Uwwww.uuu.xxxxxxx-P1-Cy-Tz-L1,
where wwww is the feature code of the system, uuu is
a set of three numbers 0-9 or letters A-F, xxxxxxx is
the serial number of the system, y is a number
greater than 0, and z is 1 or 2.
An example of an actual Slot column value is U8205.E6C.DQDMLTM-P1-C1-T1-L1.
The exact value of the identifier varies depending on the type of
server and the location of the PCIe connector. Identifiers for slots
that connect a PCIe storage enclosure terminate with -T1-L1 or -T2-L1.
- You can use identify indicators to visually confirm that an entry
represents the connection to the storage enclosure being added. Record
the PCIe connector location code, which is the slot identifier value
minus the -L1 at the end. Then, complete
the procedure in Using identify indicators to locate hardware components to
illuminate the identify indicator for the PCIe connector that is associated
with that location code.
- For each entry that you identified in step 3.a, verify
that the Description column correctly identifies the type of adapter
in the PCIe storage enclosure that is connected to that slot. Use
the following information to verify whether the system correctly identifies
the adapter:
- When the system recognizes the PCIe storage enclosure, the Description
column contains a value that resembles PCIe2 3.1GB Cache
RAID SAS Enclosure 6Gb x8. The exact string is dependent
on the type of enclosure.
- When the system does not recognize the PCIe storage enclosure,
the value in the Description column is Empty slot, Unknown,
or PCI-to-PCI bridge. To ensure that
the PCIe storage enclosure has been connected correctly, complete
the following steps:
- Verify that the PCIe cables are connected to the system and to
the PCIe storage enclosure. If you find an incorrect connection at
either end, connect the cables correctly.
- Verify that the power cables are connected to the power source
and to the power supplies on the PCIe storage enclosure, and verify
that the green enclosure power light-emitting diode (LED) is on solid.
If you find an incorrect connection at either end, connect the cables
correctly.
- If you needed to reconnect the PCIe cables or power cables, power
the system off and back on. Then repeat step 3.
If you detect no physical connection problems, or if the problem
persists after a system reboot was required, contact your next level
of support for assistance.
- Return to the procedure that sent you here.
