I have a HP Server connected to a HP EVA SAN via HBA. Today, i enlarged the lun that is attached to the server. Now the windows server shows "Disk 1" with the available allocated space in use and two other sections of unallocated space. When i total the three sections it totals the amount of space i associated to the lun. How do I use diskpart to combine the two sections of unallocated space with the already allocated space? Also, can this be done while the server is in production or will there be an interruption in service? Lastly, will the data that is currently on the allocated part of the drive be lost when the unallocated space is merged with it?
Where can I download diskpart or is it already installed?
