Troubleshooting
Problem
After a DLPAR operation, the correct resources can reflect on the partition but not on the HMC or vice versa. This failed DLPAR Operation might be solved by the rsthwres command.
Symptom
Resources mismatch between HMC and Partition.
Cause
However, a DLPAR operation can fail, an error might not appear and, the operation can complete without errors.
Environment
HMC and Partition
Diagnosing The Problem
The lshwres command might show an output like pend_mem =xxxx.
Example: lshwres -r mem -R -m <MANAGED SYSTEM NAME> --level lpar
Example: lshwres -r mem -R -m <MANAGED SYSTEM NAME> --level lpar
Resolving The Problem
Use the rsthwres command with the appropriate syntax depending on whether it is a mismatch in the memory or the CPUs
rsthwres -r {io | mem | proc} -m managed-system
[{-p partition-name | --id partition-ID}]
[-l slot-DRC-index] [--help]
Example for CPU: rsthwres -r proc -m <Managed System> -p <Partition>
This command ensures that resources are allocated correctly after any
DLPAR operation.
The command has to be run for the logical partition. It is better to run it 3 times
With 10 - 15 minutes intervals between each time.
It ensures that resource allocation is correct and then you
Might check that with the command lshwres command.
Example: lshwres -r proc -m <Managed System> --level lpar
rsthwres -r {io | mem | proc} -m managed-system
[{-p partition-name | --id partition-ID}]
[-l slot-DRC-index] [--help]
Example for CPU: rsthwres -r proc -m <Managed System> -p <Partition>
