Ucs Central Powertool 2.0.1 compare/sync within same Ucs Central does not work

Ucs Central compare/sync within same Ucs Central does not work, I get "object already exists" error and no changes made

The compare/sync function is essential for managing large Ucs Central solutions

Using:

- Ucscentral 1.4(1b)

- UcsPowerTool Suite 2.0.1, Ucs Central Powertool

Hi,

you can try the XlateMap parameter if you want to compare and sync mos in hierarchy. XlateMap is hashtable which has Dn's of difference mos as key and Dn's of reference mos as value.

PowerTool C:\> $refObj = Get-ucscentralorg -name "SubOrg1" -Hierarchy

PowerTool C:\> $diffObj= Get-ucscentralorg -name "SubOrg2" -Hierarchy

Now if you compare the $diffObj and $refObj, you will have $compareObj with all the child mos of "SubOrg1" and "SubOrg2". Again all the mo entries in the $compareObj will either be marked as to be created or deleted.  So you have to translate the dns of $diffObj so that Compare-UcsCentralMO cmdlet can compare the two objects using XlateMap parameter.

$xlateDn = @{}

$xlateDn['org-root/org-SubOrg2'] = 'org-root/org-SubOrg1'

$xlateDn['org-root/org-SubOrg2/org-SubOrg2_1'] = 'org-root/org-SubOrg1/org-SubOrg1_1'

In above, I am trying to translate two mos in the comparison result. I keep the Dns of $diffObj as keys and Dns of$refObj as value and I will use this $xlateDn in the Compare-UcscentralMo cmdlet.

PowerTool C:\> $compareObj = Compare-UcsCentralManagedObject -ReferenceObject $refObj -DifferenceObject $diffObj -XlateMap $xlateDn

Comapre/Sync cmdlets are typically used to compare across different UcsCentral.

If you want to use the Comapre/Sync functionality in same UcsCentral, then you have to use -XlateOrg or  -XlateMap parameters of Compare-UcsCentralManagedObject cmdlet.

PowerTool C:\> $refObj


Descr        : SubOrg1 Description

After Sync, description of reference object is updated with description of difference object.

Please let us know in case of more query.

This is very quick reply and it works for the MO to MO compary/sync!

And I can see, that when I compare two MOs including their children (created with -hierarchy) as I do in the below example, then only the "parent" MOs get compared and synced.

Is there a way to make the compary/sync work for the complete subtrees of two MOs (say "parentMO1" and "parentMO2"), such that both of the below will take place:

- Child MOs under the two "parents" with same "subtree" Dn's, e.g. Dn="parentMO1/ChildMO1" and Dn = "parentMO2/ChildMO1" get compared/sync'ed

- If a child object exists only under the difference "parent" object (say child "parentMO2/ChildMO7"), but not under the reference "parent" (in casu "parentMO1"), then this child will be copied as a child under the reference "parent" (here as "parentMO1/ChildMO7") (I can see that the -deleteNotPresent works ok for the "other way" by deleting children under the reference Parent, which do not exist under the difference Parent)

One way to handle a "subtree" compary/sync could be to "manually" code a "loop" down through both ParentMO subtrees, In this case I would then have to find a way to handle the situation, where a child exists under the difference Parent but not under the reference Parent. My immediate impression is, that there is no way to do compare/sync from a difference MO to a non existing reference MO.

The below test shows that my compare/sync of two subtrees created by -hierarchy only works on the two "Parent" MOs (except for the -deleteNotPresent, which does work (not shown below))

$refObj = Get-ucscentralorg -name "SubOrg1" -hierarchy

$diffObj= Get-ucscentralorg -name "SubOrg2" -Hierarchy

$compareObj = Compare-UcsCentralManagedObject -ReferenceObject $refObj -DifferenceObject $diffObj -XlateOrg "org-root/org-SubOrg1"

$refObj | select Dn

$diffObj | select Dn

$compareObj | select Dn

Sync-UcsCentralManagedObject -Difference $compareObj -Force

get-ucscentralorg | ? {$_.Name -like "*SubOrg*"} | select Name,Descr,Dn | format-table -AutoSize

Name  Descr             Dn                          
----  -----             --                          
SubOrg1   SubOrg2_1 Description org-root/org-SubOrg1         <= Update

SubOrg1_1 SubOrg1_1 Description org-root/org-SubOrg1/org-SubOrg1_1 <= No Update

SubOrg2   SubOrg2 Description   org-root/org-SubOrg2        

SubOrg2_1 SubOrg2_1 Description org-root/org-SubOrg2/org-SubOrg2_1

Compare/Sync between two MO subtrees within same Ucs Central works just fine, and I can do with only mapping the "root" Dn's of the two subtress, and then all child MOs with identical Dn's (taking the mapping of the "root" Dn's into account) get synchronized, which is just what I want for this use case. See example below for details

Questions to You:

1. Can You confirm that the above use of Sync between two subtrees within same Ucs Central where I only map the "root" Dn's of the two subtrees, is officially supported by Cisco, and that I am not in "this works but You are on Your own, if issues occur" territory?

2. The compare object generated by the compare operations only contains information ($compareObj.DiffProperty)

about which properties within a given MO, that are different in the two subtrees,

but not the values of these properties in respectively the "reference" and "difference" objects.

Is there any (automatic) way to get the value of these differing properties in both the "reference" and "difference" objects? Here I am thinking of the compare/sync process providing this information directly.

3. I would like to copy a given MO subtree to another place in the "total" subtree within the same Ucs Central system, where this subtree does not exist beforehand. So this is a genuine copy function, not a compare/sync function. Is there a feature to perform this or is Cisco planning to make such feature later (and when). (I understand this will involve some "below the surface" copying functionality since we are working with Powershell objects and "real" objects within the Ucs Central DME itself).
