Retrieve an Existing Storage Profile from the Storage Policy Server

The following code fragment shows the example function getPbmProfileSpec that uses the PbmQueryProfile and PbmRetrieveContent methods to retrieve storage profiles. In the context of the Storage Policy SDK example VMCreate.java, the function returns a VirtualMachineDefinedProfileSpec to be used to configure storage for a virtual machine.

The function performs the following operations:

1	Uses the connection to the Storage Policy Server to retrieve a reference to the Profile Manager.

2	Calls the PbmQueryProfile method to obtain the list of storage profile identifiers.

3	Calls the PbmRetrieveContent method to obtain the list of storage profiles.

4	Finds the profile that matches the specified profile name.

5	Creates a VirtualMachineDefinedProfileSpec and assigns the identifier from the named profile to the VirtualMachineDefinedProfileSpec. You use the VirtualMachineDefinedProfileSpec when you configure the virtual machine. See Apply the Storage Profile to a Virtual Machine.

Example: Retrieving a Storage Profile

VirtualMachineDefinedProfileSpec getPbmProfileSpec(String name)

throws InvalidArgumentFaultMsg, com.vmware.pbm.RuntimeFaultFaultMsg,

RuntimeFaultFaultMsg {

 

// 1 Get PBM Profile Manager

PbmServiceInstanceContent spbmsc = connection.getPbmServiceContent();

ManagedObjectReference profileMgr = spbmsc.getProfileManager();

 

// 2 Retrieve the list of profile identifiers.

List<PbmProfileId> profileIds =

connection.getPbmPort().pbmQueryProfile(profileMgr,

PbmUtil.getStorageResourceType(),

null);

 

if (profileIds == null || profileIds.isEmpty())

throw new RuntimeFaultFaultMsg("No storage Profiles exist.", null);

 

// 3 Retrieve the list of storage profiles.

List<PbmProfile> pbmProfiles =

connection.getPbmPort().pbmRetrieveContent(profileMgr, profileIds);

 

// 4,5 Find the named profile and create a VirtualMachineDefinedProfileSpec

// that will use the same profile identifier.

for (PbmProfile pbmProfile : pbmProfiles) {

if (pbmProfile.getName().equals(name)) {

PbmCapabilityProfile profile = (PbmCapabilityProfile) pbmProfile;

VirtualMachineDefinedProfileSpec spbmProfile =

new VirtualMachineDefinedProfileSpec();

 

spbmProfile.setProfileId(profile.getProfileId().getUniqueId());

 

return spbmProfile;

}

}

 

// Throw exception if none found

throw new InvalidArgumentFaultMsg(

"Specified storage profile name does not exist.", null);

}
