Error when adding datastore in VMware ESXI 5

Posted on 2011-09-15
Last Modified: 2012-05-12
Hello Experts,

I just installed VMware's ESXi 5.0 on a new server of ours. I also made sure the Hardware and Raid controller was compatible before purchasing. I installed the Hypervisor on a flash drive and am planning on using the Raid Controller for the datastore.

Raid info:
PERC 6/i SAS internal RAID adapter, PCI-Express

The storage shows up under devices and everything looks fine.(See devices.jpg)

When I try to add it to a datastore I get this error:

"The operation failed because the specified directory path is incorrect."

Recent Task:
Create VMFS datastore
A specified

I have several esxi host and this is the first time I have seen this problem and google isn't helping. Can someone help me figure this out?

It's possibly because it already has a partition on it. (all the other versions do this if there is a partition on the disk!)

Remove the partition with GPartED Live CDROM.
Download Gparted Live CDROM (

or Scrub the disks, if you have that option on the RAID controller.

This is a remote server which I can access through the iDRAC6 Management card. I do believe I can mount a local cd and boot from it, I will have to check. Is there a reason a partition already exist on the new server? No OS was shipped with it so unless it is used for something else I don't understand. I just don't want to remove a partition before knowing it doesn't effect anything.

I have no idea, but if you look at the screenshot, it believes there is a Win 95 FAT32 2GB partition on the RAID array.

The only way of checking is using another disk manager.

Were the disks new?

It's certainly not an ESXi 5.0 partition.

You could also check with fdisk at the console, but sometimes, it's difficult to "nuke" a partition whilst ESXi is memory resident.

Yes, okay, so you've got a Dell Management partition, Fat 16 and Fat32 OS partition.

Remove them both, and clear the disk.

Don't have support right now. I was able to finally figure it out. I didn't think it would matter if I renamed the name of the device. But apparently it does. I right clicked the device and selected "Copy identifier to clipboard" and pasted this as the name. Tried it again and it worked.

 Result after renaming device

Figured out that you can't rename the device name. Changed it back and everything worked. It was also helpful to know to remove all partitions before adding it to a datastore. Thanks.

It clearly didn't like your SAS name, which is the first error specified directory path is incorrect.

But with partitions on the device, it would not have created the VMFS datastore.
