Hi,

I have to create a disk of total Size 200 GB. So i chose VIXDISKLIB_DISK_MONOLITHIC_SPARSE disk to be created so it can grow as the size increases,

// Fill createParams for target
createParams.adapterType = VIXDISKLIB_ADAPTER_IDE;
createParams.capacity = 419430400;
createParams.diskType = VIXDISKLIB_DISK_MONOLITHIC_SPARSE;




VixError vixError = VixDiskLib_Create(_conn, vmdkFilePath.c_str(), &createParams, NULL, NULL);
CHECK_AND_THROW(vixError);

this craete API creates 25 MB file.Is it normal ? Is so does the size of file increase depending upon createParams.capacity ? Why is so ?

Please help.

/Thanks
