Worked through process to clean up packages per DOC7970 (pg 25) and worked through the steps on the Console as outlined in HOWTO38239, yet after these steps were completed, found the Software Update Packages remained on the downloaded storage location of the SMP Server and the Site/Package Servers.
Some known causes:
Run the following Script against the 7.5 - 8.0 Symantec_CMDB database, or implement the following query (blue text) into a custom SQL Report on the Console, to confirm the associations still exist:
declare @AllPatchPackages as table (_ResourceGuid
insert into @AllPatchPackages
EXECUTE sppGetAllPatchPackages @platform=N'Windows'
,vsb.name as Bulletin
,i.name as [Software Update]
,it.Name as 'Resource Association'
from vRM_Package_Item i
left join ResourceAssociation ra on i.guid = ra.ChildResourceGuid
and ra.ResourceAssociationTypeGuid = 'A19CED33-9E1F-4E97-98CF-0F8B339739C3'--Software Update Created Software Package
left join Item it on it.Guid = ra.ResourceAssociationTypeGuid
left join Inv_Software_Update su on su.filename=i.name
left join ResourceAssociation sb2su on su._ResourceGUID=sb2su.childresourceguid
left join vRM_Software_Bulletin_item vsb on vsb.guid=sb2su.ParentResourceGuid
left join @AllPatchPackages ap on ap._ResourceGuid = ra.ChildResourceGuid
where i.ProductGuid = 'B1338338-5575-4A27-9808-23BEC40D79FA'--Patch managmenent
and i.Name not in
'Patch Install Tools Package',
'Patch Windows System Assessment Scan Tool Package',
'Windows x86 Software Update Plug-in Package',
'Windows x64 Software Update Plug-in Package'
and (ra.ResourceAssociationTypeGuid is null or ap._ResourceGuid is null)
