Learn how to add a PCIe storage enclosure to the system
with the system powered off.
Notes: - Depending on the feature of PCIe storage enclosure that you are
working with, you might be able to add it to the system with the system
powered on and the logical partitions active. To learn which options
you have for adding your PCIe storage enclosure to the system, read
the following information:
- If you are adding a 5888 PCIe storage
enclosure, you must use this procedure to add the enclosure to the
system with the system powered off.
- If you are adding any other PCIe storage enclosure, you can use
this procedure to add the PCIe storage enclosure to the system with
the system powered off, or you can use Adding a PCIe storage enclosure with the system powered on instead of this procedure
to add it with the system powered on.
- To learn about the different options for cabling PCIe storage
enclosures to the system, see Connecting PCIe storage enclosures with PCIe cables.
- Steps in this topic require you to have connector information
for the hardware in your configuration. For details about PCIe storage
enclosure or system connector locations, see Connector
locations.
To add a PCIe storage enclosure to the system with the
system powered off, complete the following steps:
- If the system is not already powered off, remove
power from the system. For details, see Stopping
a system or logical partition
Important: If the PCIe storage enclosure is connected to two
systems, complete this step for each system.
- If the system has a rear cover, remove or open
it.
Important: If the PCIe storage enclosure is connected
to two systems, complete this step for each system.
- Locate the PCIe GX++ adapter or adapters to which
the PCIe storage enclosure will be connected.
Note: This procedure
assumes that the PCIe GX++ adapters are already installed. If the
adapters are not installed, stop now and follow the instructions that
came with the GX adapters to install them. After the PCIe GX++ adapters
are installed, continue with the steps in this procedure to add the
PCI storage enclosure.
- Using PCIe cables, connect the PCIe storage
enclosure to the PCIe GX++ adapters that you identified in step 3.
Note: If you
are connecting a PCIe cable to an unused PCIe connector that is covered
with a plastic or metal clip, remove the clip before installing the
PCIe cable.
- If the system has a rear cover, close it.
Important: If the PCIe storage enclosure is connected to two
systems, complete this step for each system.
- If the power cords for the PCIe storage enclosure
are not connected to the power source, connect them now. Then connect
the power cords to the power supplies on the PCIe storage enclosure.
- Record the current date and time for use
later in the procedure when checking for serviceable events.
- Power on the system. For details, see Starting the system or logical partition.
- Verify the PCIe hardware topology by completing
the steps in the applicable procedure:
While you are completing the verification steps of that procedure,
confirm that the PCIe links that connect the PCIe storage enclosure
being added have Link Status column values of Operational and
valid I/O Enclosure Port column values. The I/O Enclosure Port column
value looks similar to Uxxxx.001.yyyyyyy-P1-Cz-T3,
where xxxx is the feature code of the PCIe storage
enclosure connected by the PCIe link, yyyyyyy is
the serial number of the PCIe storage enclosure connected by the PCIe
link, and z is either 1 or 2.
An example of an actual I/O Enclosure Port column value is UEDR1.001.6BAH004-P1-C1-T3.
Important: If the PCIe storage enclosure is connected to two
systems, complete this step for each system.
Requirement: All PCIe hardware topology problems
that are discovered in this step must be corrected before continuing
with this procedure.
- Check for and handle new serviceable events
that were generated during the procedure by completing the steps in Checking for new serviceable events.
Use the date and time information that you recorded in step 7 as the
start time for searching for new serviceable events.
Important: If the PCIe storage enclosure is connected to two
systems, complete this step for each system.
- Verify the new configuration. For details,
see Verifying that the PCIe storage enclosure is functioning.
- If the system is managed by an HMC, is not in the manufacturing
default configuration, and the I/O slots associated with the connection
to the PCIe storage enclosure are not assigned to logical partitions,
you can now assign them. For information about adding I/O slots to
partitions dynamically, see Adding physical I/O devices and slots dynamically.
