HMC Tips V - DLPAR Operations

1. To list the memory by system level :
# lshwres -r mem -m Managed-System --level sys
2. To list the memory by lpar level :
# lshwres -r mem -m Managed-System --level lpar
3. To list the processor / processing units by system level :
# lshwres -r proc -m Managed-System --level sys
4. To list the processor / processing units by lpar level :
# lshwres -r proc -m Managed-System --level lpar
5. To list the processor / processing units by pool level :
# lshwres -r proc -m Managed-System --level pool
6. To add 1GB of memory to an lpar dynamically :
# chhwres -r mem -m Managed-System -o a -p Lpar_name -q 1024
7. To remove 1GB of memory to an lpar dynamically :
# chhwres -r mem -m Managed-System -o r -p Lpar_name -q 1024
8. To move 1GB of memory from lpar_a to lpar_b dynamically :
# chhwres -r mem -m Managed-System -o m -p Lpar_a_name -t Lpar_b_name -q 1024
9. To add 1 dedicated cpu to an lpar dynamically :
# chhwres -r proc -m Managed-System -o a -p Lpar_name -procs 1
10. To remove 1 dedicated cpu to an lpar dynamically :
# chhwres -r proc -m Managed-System -o r -p Lpar_name -procs 1
11. To move 1 dedicated cpu from lpar_a to lpar_b dynamically :
# chhwres -r proc -m Managed-System -o m -p Lpar_a_name -t Lpar_b_name -procs 1
12. To add 0.5 processing unit to an lpar dynamically :
# chhwres -r proc -m Managed-System -o a -p Lpar_name -procunits 0.5
13. To remove 0.5 processing unit to an lpar dynamically :
# chhwres -r proc -m Managed-System -o r -p Lpar_name -procunits 0.5
14. To move 0.5 processing unit from lpar_a to lpar_b dynamically :
# chhwres -r proc -m Managed-System -o m -p Lpar_a_name -t Lpar_b_name -procunits 0.5
15. To restore memory resources on a lpar based on its profile :
# rsthwres -r mem -m Managed-System -p Lpar_name
16. To restore memory resources for all partitions in a managed system :
# rsthwres -r mem -m Managed-System
17. To restore processing resources on a lpar based on its profile :
# rsthwres -r proc -m Managed-System -p Lpar_name
18. To restore processing resources for all partitions in a managed system :
# rsthwres -r proc -m Managed-System
19. To restore physical I/O slots on a lpar based on its profile :
# rsthwres -r io -m Managed-System -p Lpar_name
20. To restore physical I/O slots for all partitions in a managed system :
# rsthwres -r io -m Managed-System
