Hi
I would do this:
1. create new Linux VM - or use a physical machine
2. boot into this LiveCD : http://sanbarrow.com/mcs-esxi5-recovery-X-001.iso
3. connect to iSCSI target with open-iscsi (google can help with instructions)
4. after successful mount check content of the volume with
vmfs-fuse /dev/sda /mnt

Hello,

Can you upload the vmkernel or messages logs from the host ?

Logs should indicate the cause for this.

If you could upload the logs, we could review it and then provide the correct step for resolving the issue.

Cheers,

I have analaize my lost drives and found that my files are there. I purchased DiskGuru and downloaded some files off VM's. Anyone knows how to write new partition without formating it? esxi sees this drives as new.

This are my files:

can you please upload the vm-support logs

http://kb.vmware.com/kb/653

Regards,

NS

[FedericoAlves]

I did exactly what you suggest and I get this

root@mcs:~# vmfs-fuse /dev/sda3 /mnt
VMFS VolInfo: invalid magic number 0x00000000
VMFS: Unable to read volume information
Trying to find partitions
Unable to open device/file "/dev/sda3".
Unable to open filesystem

Is there a way to mount my partition again?
