Using VCEM subranges in a federated CMS environment
In a federated CMS environment, it is critical to select unique pre-defined VCEM subranges during
HP Insight Management DVD installation for each CMS in the federation. This prevents the different
VCEM instances from using MAC or WWNs which belong to other instances. This also results in
an automatic creation of VCEM exclusion ranges for MAC or WWNs which do not belong to a
particular VCEM instance.
Transferring managed VC domains from one VCEM instance to another
Use the procedure in the following example to transfer a managed VC Domain from one VCEM
instance to another VCEM instance.
1.
Remove VC Domain A from the VCEM VC Domain Group which resides in the source CMS.
2.
Power off CMS#1. This guarantees that no more than one VCEM instance is using that same
#01 subrange.
NOTE:
CMS#1 cannot be powered on again unless you provide a new VCEM subrange.
If you want to use CMS#1 for other purposes, you must uninstall it along with the whole Insight
Management stack or guarantee that the CMS will be cleaned by either installing a new
operating system or reformatting the hard disk.
3.
At the CMS#2 target, browse to the MAC address management page and remove MAC
exclusion range #01.
4.
At the target CMS, browse to the WWN management page and remove exclusion range
#01 from the VCEM-defined range.
5.
At the target CMS, import VC Domain A into the VCEM VC Domain Group

Consolidating multiple VCEM instances into a single VCEM instance
Use the following example scenario to transform multiple VCEM standalone instances (VCEM
subranges) into a single VCEM instance (big pool):
Consider that you have 3 central management systems (CMS), CMS#1 is using subrange #1,
CMS#2 is using subrange #2 and CMS#3 is using subrange #3, in a multi-CMS system or in the
Federated HP IO environment. You want CMS#2 to be the only CMS in a single VCEM instance.
1.
At CMS#1, remove the VC Domain A from the VCEM VC Domain Group.
2.
Power off CMS#1. This guarantees that no more than one VCEM instance is using that same
#01 subrange.
3.
At the CMS#2 target, browse to the MAC address management page and remove the MAC
exclusion range #01.
4.
At CMS#2, browse to the WWN management page and remove the exclusion range #01.
5.
At CMS#2, import VC Domain A into the VCEM VC Domain Group.
6.
At CMS#3, remove VC Domain C from VCEM VC Domain Group.
7.
Power off CMS#3. This guarantees that no more than one VCEM instance is using the same
#03 subrange.
8.
At the CMS#2 target, browse to the MAC address management page and remove the MAC
exclusion range #03.
9.
At CMS#2, browse to the WWN management page and remove exclusion range #03.
10. At CMS#2, import VC Domain C into the VCEM VC Domain Group.
11. At CMS#2, remove all other VCEM pre-defined subranges from the exclusion list. This returns
the available addresses into a single large pool.
