Does the customer have an available alternate load source that can be
switched?
Yes No
↓ There is no alternate load source for the logical partition.
7. Have the customer switch the IOP with an available alternate load source to
the logical partition that requires an alternate load source. Have the customer
mark the IOP as the alternate IPL resource and note the alternate load
source-physical location.
Locating a secondary partition’s load source from the primary
partition’s console
Use this procedure to locate a logical partition’s load source and alternate load
source in a system that has logical partitions by using the console of the primary
partition.
Note: The logical partition identifier or partition name is required to perform this
procedure.
The partition number is the last two digits in the logical serial number of the
logical partition.
1. Go to the console of the primary partition.
2. From the SST or DST display, select the Work with system partitions option.
3. At the Work with System Partitions display:
a.
Record the partition management release.
b. Record the number of partitions.
c. Select Display partition information.
4. At the Display Partition Information display, select Display allocated I/O
resources.
a.
Locate the secondary partition and look for its load source. The load source
and alternate IPL resource are tagged on the screen under the logical
partition’s IOP information. Note that the logical partition may not have an
alternate IPL resource. Note the logical address of the load source and
alternate IPL resource. Use the logical address to determine where the
physical
load source is located.
b. If the logical partition does not have an alternate IPL resource and one is
needed, perform the following:
1)
Determine if the customer has an alternate IPL resource that can be
switched to this logical partition.
Does the customer have an available alternate IPL resource that can be
switched?
Yes No
↓
There is no alternate IPL resource for the logical partition.
2) Have the customer switch the IOP with an available load source to the
logical partition that requires an alternate IPL resource. Have the
customer mark the IOP as the altenate IPL resource and note the
alternate IPL resource-physical location.
