must
stop all applications, including console applications, and subsystems
that are running in
all
logical partitions, before the delayed power-off
operation is complete.
Attention:
Using the control panel power push-button to power off the system
may cause unpredictable results in the data files, and the next IPL will take longer
to complete.
Powering Off a Secondary Partition
Attention:
Powering off a secondary partition will not power off any expansion
tower(s) that the partition owns. If it is necessary to power off the expansion
tower(s) owned by the secondary partition, use the “Expansion Tower and SPCN
Controlled Expansion Unit Power Procedure”. Power off the secondary partition(s)
before powering off the expansion tower(s) owned by the logical partition(s).
If the secondary partition is operating under Dedicated Service Tools (DST), power
off the logical partition by selecting the
Power Off the System
option on the
Start a
Service Tool (SST)
display of the secondary partition’s console.
Note:
To locate the secondary partition’s console or alternative console, see
iSeries
Service Functions
.
If the secondary partition is operating under OS/400, from the logical partition’s
console enter the
PWRDWNSYS
command to power off the secondary partition.
Note:
For consoles on the secondary partition that run Client Access, a delayed
power-off operation by using the
PWRDWNSYS
command is required. You
must
stop all applications, including console applications, and subsystems
that are running in the
secondary
partition before the delayed power-off
operation is complete.
If the secondary partition fails to power off
or
if the console of the secondary
partition is not functioning:
1.
Go to the console of the Primary partition.
2.
From the
Use Dedicated Service Tools (DST)
screen, select the
Work with System
Partitions
option.
3.
At the
Work with System Partitions
screen:
a.
Select the
Work with Partition Status
option.
b.
Select the
Power off Delayed
option and press enter.
If the secondary partition fails to power off then go to “Powering Off a System
with Multiple Logical Partitions Using the Control Panel or Primary Partition’s
Console” on page 925.
Expansion Tower and SPCN Controlled Expansion Unit Power
Procedure
Attention:
If there is an SPD migrated tower on the HSL loop with this tower,
then follow this procedure very carefully. This procedure will help you determine
if the SPD migrated tower is the next tower (leading link) or the previous tower
(trailing link) from this tower on the loop. Powering down a tower when the next
tower or the previous tower on the loop is an SPD migrated tower will cause a
machine check that will crash the entire system.
