Hi Vijay,
I was wondering - if you had a few moments - if you might give me some
pointers on how to translate this code I've written in the VI Java API to
the VI API, which we use in CloudStack?
Below is my createVmfsDatastore method.
Thanks for any time you might be able to spend on this!
public static void createVmfsDatastore(String url, String username, String
password, String datacenterName, String clusterName,
String datastoreName, String storageIpAddress, Integer portNumber, String
iqn) throws Exception
{
ServiceInstance si = new ServiceInstance(new URL(url), username, password,
true);
ManagedEntity datacenter =
si.getSearchIndex().findByInventoryPath(datacenterName);
if (datacenter == null)
{
throw new Exception("Datacenter '" + datacenterName + "' was not found.");
}
InventoryNavigator inventoryNavigator =
newInventoryNavigator(si.getRootFolder());
ClusterComputeResource cluster =
(ClusterComputeResource)inventoryNavigator.searchManagedEntity(
"ClusterComputeResource", clusterName);
if (cluster == null)
{
throw new Exception("Cluster '" + clusterName + "' was not found.");
}
HostSystem[] aHostSystems = cluster.getHosts();
if (aHostSystems == null || aHostSystems.length == 0)
{
throw new Exception("There are no hosts in cluster '" + clusterName + "'."
);
}
HostInternetScsiHbaStaticTarget target = newHostInternetScsiHbaStaticTarget();
target.setAddress(storageIpAddress);
target.setPort(portNumber);
target.setIScsiName(iqn);
HostInternetScsiHbaAuthenticationProperties auth =
newHostInternetScsiHbaAuthenticationProperties();
String strAuthType = "chapRequired";
auth.setChapAuthEnabled(true);
auth.setChapInherited(false);
auth.setChapAuthenticationType(strAuthType);
auth.setChapName("admin");
auth.setChapSecret("solidfire");
auth.setMutualChapInherited(false);
auth.setMutualChapAuthenticationType(strAuthType);
auth.setMutualChapName("admin2");
auth.setMutualChapSecret("solidfire2");
target.setAuthenticationProperties(auth);
HostInternetScsiHbaStaticTarget[] aTargets =
newHostInternetScsiHbaStaticTarget[1];
aTargets[0] = target;
for (HostSystem hostSystem : aHostSystems)
{
boolean iScsiHbaConfigured = false;
HostStorageSystem hostStorageSystem = hostSystem.getHostStorageSystem();
for (HostHostBusAdapter hba :
hostStorageSystem.getStorageDeviceInfo().getHostBusAdapter())
{
if (hba instanceof HostInternetScsiHba)
{
// just finding an instance of HostInternetScsiHba means that we have
found at least one configured iSCSI HBA
// at least one iSCSI HBA must be configured before a CloudStack user can
use this host for iSCSI storage
iScsiHbaConfigured = true;
String iScsiHbaDevice = hba.getDevice();
hostStorageSystem.addInternetScsiStaticTargets(iScsiHbaDevice,
aTargets);
hostStorageSystem.rescanHba(iScsiHbaDevice);
}
}
if (!iScsiHbaConfigured)
{
throw new Exception("An iSCSI HBA must be configured before a host can
use iSCSI storage.");
}
}
HostDatastoreSystem hostDatastoreSystem =
aHostSystems[0].getHostDatastoreSystem();
HostScsiDisk[] aHostScsiDisks =
hostDatastoreSystem.queryAvailableDisksForVmfs(null);
HostStorageSystem hostStorageSystem =
aHostSystems[0].getHostStorageSystem();
HostScsiDisk hostScsiDisk =
getHostScsiDisk(hostStorageSystem.getStorageDeviceInfo().getScsiTopology(),
aHostScsiDisks, iqn);
if (hostScsiDisk == null)
{
throw new Exception("A relevant SCSI disk could not be located to use to
create a datastore.");
}
// just grab the first instance of VmfsDatastoreOption
VmfsDatastoreOption vmfsDatastoreOption =
hostDatastoreSystem.queryVmfsDatastoreCreateOptions(hostScsiDisk.getDevicePath())[0];
VmfsDatastoreCreateSpec vmfsDatastoreCreateSpec =
(VmfsDatastoreCreateSpec)vmfsDatastoreOption.getSpec();
// set the name of the datastore to be created
vmfsDatastoreCreateSpec.getVmfs().setVolumeName(datastoreName);
Datastore datastore =
hostDatastoreSystem.createVmfsDatastore(vmfsDatastoreCreateSpec);
if (datastore == null)
{
throw new Exception ("Datastore '" + datastoreName + "' could not be
created.");
}
System.out.println("Datastore '" + datastoreName + "' was successfully
created.");
}
