VMFS Partitions Stored on Corrupted RAID Controller
Corrupted RAID arrays are one of the two main things that can lead to a Virtual Machine File System, (VMFS) failure, the second being damaged blocks. These are not all there are to a VMFS failure but they are the two most common reasons why VMFS failures happen. However, restoring lost data is not an impossibility. This is where VMFS recovery comes in; a tool designed for anyone who uses virtual machines whether VirtualPC, VirtualBox, VMware, Parallels EnCase or any other. This tool additionally comes with vSphere 6 as well as ESX server support.
VMFS recovery is capable of providing repair for a corrupted RAID array whether or not a RAID controller is available or accessible. That is, even if the RAID controller is inaccessible, recovery is still possible. With the help of JBOD, VMFS, RAID 0 Recovery can restore virtual machine disks from any hard drives whether they are corrupted or safe. It will by this, give the hard drive access to the corrupt data and thereby recovering it as though it were from a Virtual Machine File System disk that had no issues.
This recovery tool from Reclaim me supports VMFS partitions of up to 64 terabytes, files up to 2 terabytes as well as even VMFS5 drives that have over one million files stored in them.
Data Analyzers told us that there are two modes available for you to choose from in carrying out the recovery process; the fast mode which you can use for the recovery of existing or deleted files or the full mode which you can use to enable the recovery of your data in more difficult situations.
Virtual PC images can be recovered from ESX servers. First, an ESX / ESXi storage which has been previously damaged is recovered. After this has been done, VMFS recovery will get access to separate virtual machines as well as their VDMK disks. And then the recovery procedure will be carried out.
In order to be able to run the VMFS recovery, you will need at least a standard PC that comes with Windows XP or something higher. It is best, however, to use Windows 8 or 7 with a 4GB RAM and above. This is because the software would build in RAM, a complete VMFS structure before the recovery process takes place. You will also need more RAM if you have bigger VMFS disks or ESX server. In other words, the bigger the ESX server or VMFS disks you have, the more RAM you will need for a successful recovery process.
In addition, you should have it in mind that Virtual Machine File System recoveries would also require up to 16 megabyte space to enable installation. It will also need quite an amount of usable space on the disk where the recovered data can be saved. Basically, however, so much of this would depend on the size of the data you need to recover.
