Re: How to recover VMFS volume after a RAID controller failure

Ye, i think I have understand why do you ask.

In the link you have provided, there are two types or partitions - MBR and GPT (which maybe is from gParted).

They say that for legacy MBR disks, fdisk have to be used.

I have tried to execute fdisk -l, but the output was

"Found valid GPT with protective MBR; using GPT"

fdisk: Sorry, cant't handle GPT partitions, use partedUtil

Regarding this output and the arcticles i have read, i assume that i have to use 2048.

So, i assume that I have to execute the following command. Can you please check it as well, so i can be more assertive before executing it:

 

partedUtil setptbl /vmfs/devices/disks/mpx.vmhba1\:C0\:T1\:L0  gpt "1 2048 3895451647 AA31E02A400F11DB9590000C2911D1B8 0"

 

Few things i still don't understand:

  1. after the gpt, there is a "1". What is it for and should it be 1 in my case?
  2. After GUID there is a "0". What is it for and should it be 0 in my case?
  3. Will this command destroy my data (VMDK files)?
