In-Depth Information
We recommend that you use as descriptive a name as possible. You might also consider
using a naming scheme that includes an array identii er, a LUN identii er, a protection
detail (RAID type and whether it is replicated remotely for disaster recovery purposes),
or other key coni guration data. Clear datastore naming can help the vSphere adminis-
trator later in determining VM placement and can help streamline troubleshooting if a
problem arises.

Select the LUN on which you want to create the new VMFS datastore.
For each visible LUN, you will see the LUN name and identii er information, along with
the LUN. Figure 6.34 shows two available LUNs on which to create a VMFS datastore.

You'll choose from
a list of available
LUNs when creat-
ing a new VMFS
datastore.
After you've selected the LUN you want to use, click Next.
8.
Select whether you'd like to create a VMFS-5 datastore or a VMFS-3 datastore.
We described the differences between VMFS-5 and VMFS-3 in the section titled
“Examining the vSphere Virtual Machine File System.” Click Next after selecting a
version.
9.
The next screen, displayed for you in Figure 6.35, shows a summary of the details of the
LUN selected and the action that will be taken; if it's a new LUN (no preexisting VMFS
partition), the wizard will note that a VMFS partition will be created.
