– The resources representing the partition's LAN connection to the HMC, such as ent0 and en0,
must not be unconfigured or the procedure will not work. If these resources use the expansion
unit, the partition must be powered off to continue with the procedure.
Attention: If resources in the expansion unit are assigned to I/O server partitions and are being
used by I/O server partitions (also known as virtual I/O servers), work with the customer to
determine whether powering off the expansion unit will negatively impact the client partitions. If so,
the client partitions should be powered off before continuing.
13. Power off all external DVD-RAM storage devices (containing their own power supplies) connected
to resources in the expansion unit, and then go to step 14.
14. Use one of the following procedures to power off the expansion unit. Carefully follow the
instructions provided by the utility to complete the power off.
Attention: If the server is not managed by a management console and there is no IBM i service
partition, the expansion unit power cannot be turned off with the server power turned on.
To turn off the power in an expansion unit with the server power on, do one of the following
procedures:
v If the server is HMC-managed, the power off and power on functions must be performed by
using the Power On/Off Unit utility on the HMC.
– For HMC V6R1.3 and earlier, do the following steps:
a. In the navigation area, open the Service Applications folder.
b. Select Service Focal Point.
c. In the contents area, select Service Utilities.
d. In the Service Utilities window, select the system on which you are working.
e. Select Selected > Power On/Off Unit
– For HMC V7 and later, do the following steps:
a. Select the managed system, then select Serviceability -> Hardware -> Power on/off IO
Unit.
b. In the Power on/off IO Unit window, expand the Managed system I/O and select the
appropriate unit.
c. Click the Power off button.
– For the IBM Systems Director Management Console (SDMC), complete the following steps:
a. On the Welcome page, under the Resources tab, select the server.
b. Click Actions > Service and Support > Hardware > Power on/off IO Unit.
v If the server is not managed by a management console, the power off and power on functions
must be performed by using the Packaging Hardware Resources utility from the IBM i service
partition, do the following steps:
a. Access the system service tools or the dedicated service tools on the IBM i service partition.
b. Select Start a service tool.
c. Select Hardware service manager.
d. Select Packaging hardware resources.
e. Select Concurrent maintenance.
