IBM Power System POWER7 Series, Общие процедуры обслуживания

Страница: 159 / 198

Attention: Do not use this procedure in either of the following situations:
v
To replace disk units that are supported under device concurrent maintenance. Use the device
concurrent maintenance procedure instead.
v
On the system unit or the system unit's integrated I/O enclosure. For system units and system units
integrated I/O enclosures, see the "Powering on or off a system". This procedure is located in your host
system's service information.
Notes:
1. References to the console in this procedure refer to the console of the logical partition in which you
are working.
2.
Throughout this procedure, the term HSL I/O bridge is interchangeable with RIO adapter .
3. Messages that may be generated on the HMC during the procedure refer to specific partitions by their
partition IDs. A partition ID is a numeric value that represents the order in which the partitions were
created. The partitions listed in the Server Management content area are not necessarily listed in order
of partition ID. A partition ID is listed under the
General tab in the Partition Properties.
Perform the following with the assistance of the customer.
1. If the ac power cords were disconnected when the enclosure was powered off and have not been
reconnected, reconnect them now. If they are already connected, go to step 2.
v The enclosure will automatically power on when the ac power cords are connected.
v
If this is a System i
®
server that is not managed by an HMC, go to step 2.
v
If this is a server managed by an HMC, power off the enclosure again. See “Powering off an
expansion unit” on page 137. Then go to step 3.
2. Were you instructed to perform a function 69 to power on the enclosure?
No: Go to step 3.
Yes: Perform function 69 (with the control panel set to manual mode) from the system unit
control panel. See Control panel functions. Then go to step 4.
3. Power on the enclosure using either the Power On/Off Unit utility from the HMC, or the Packaging
Hardware Resources utility from the IBM i service partition, as described at the top of this page.
Follow the instructions provided by the utility. Go to step 4.
Note: If you are required to do this step by using the Packaging Hardware Resources utility from
the IBM i service partition, but the Packaging Hardware Resources utility cannot be accessed, you
might be able power on the enclosure by using the system control panel as follows:
a.
With the control panel set to manual mode, select function
07
and press Enter.
b. Increment to A1 and press Enter. This will send out a Rack Power On command is issued on the
SPCN, which will restore power any enclosure that is powered off.
c.
For further information about control panel functions and how to use them, see Control panel
functions.
4. Wait for I/O resources in the enclosure to be brought back online to a functional state, and then
continue with the next step.
It may take between five and ten minutes after the enclosure is powered on for IBM i resources in
the enclosure to return to a operating state. Using the Packaging Hardware Resources and Logical
Hardware Resources utilities in the hardware service manager, you can determine when resources in
the enclosure return to a operating state by observing the transition of the resources from
non-reporting (designated by a "?" next to the resources) to reporting (designated by the absence of a
"?" next to the resources) or Unknown, Not Connected, Failed, or Disabled status to Operational
status. If there is a disk unit attention SRC in the partition operator panel and the hardware service
manager is not available, the transition to functional/operational has occurred when the disk unit
attention SRC disappears and the partition resumes normal operation.
