Esxi5.1 the error "bank5invalidconfiguration" cannot be started due to power failure

Because you are in a hurry, there is no processing process. Here we will briefly describe the entire process.

The IBM pcserver x3850 may be the cause of the machine being too hot. The power loss at noon caused esxi to fail to start properly.
Startup Error
Bank5 invalid configuration no hypervistor found

The boot disk has the option to retain the original datastore, but it has not been tried. Therefore, the VM is backed up first.
Backup:
Use linux live cd to mount a mobile hard disk for backup: systemrescumcm is simple and easy to use. : Http://jaist.dl.sourceforge.net/project/systemrescuecd/sysresccd-x86/4.2.0/systemrescuecd-x86-4.2.0.iso systemrescuecd-x86-4.2.0.iso
(This image should be part of 32 or 64. I will use a 64-bit operating system to directly access the command line)

After using nero or other tools to burn data, the pc server selects cd/dvd to start and then enters linux.
In this case, the data is not lost. When fdisk-l sees sda1, but directly uses the ll/dev/sda * command, many of them can be seen, create a directory Mount accordingly. Mkdir/mntN mount/dev/sdaN/mntN found that sda3 could not be mounted, because this is a vmfs type file system, so here also need to download a vmware-tools software: http://glandium.org/projects/vmfs-tools/vmfs-tools-0.2.5.tar.gz
If you want to log on remotely (ensure that the network cable is plugged in), you can set the root password first, so that you can use secure crt to log on or upload something.
Run the command vmfs-fuse/dev/sda3/mnt3 after decompression. If the/mnt3 directory is not empty, run vmfs-fuse-o nonempty/dev/sda3/mnt3.

In the past, this sda3 was the place where the virtual machine was stored. Then we mounted the mobile hard disk.
This live cd is considerate because it directly supports the ntfs file system and does not need to download additional packages.
Read/write mounting can be achieved directly using ntfs-3g/dev/sdb1/udisk

Then we copy all the VM files to the mobile hard disk to complete the backup. (This process is slow. It is better to hang it and then do something else on your own)
We have backed up the data so that it can be restored.
Recovery:
After restarting, add the esxi5.1 image disc to the pc server.

After scanning the hardware device. There are two options:
Retain the original datastore (in English on the Interface) and rewrite the original datastore

Since we want to fix it, we must select the first one.

After the program is re-installed, the original virtual machine will not automatically appear.
Memory browsing required







Right-click the vmx file and the configuration will be added to the configuration. Now the restoration is complete.

In fact, if the data is not very important, you can skip the backup process. But who makes me a DBA.
