Delete disk partitions by mistake in ESXi

Delete disk partitions by mistake in ESXi

Because you are not familiar with ESXi commands and are careless, you accidentally delete the partitions of the ESXi operating system. The operation procedure is as follows:

Obtain disk device information:

[Root @ localhost: ~] Fdisk-l

[Root @ localhost: ~] Fdisk-l

***
* ** The fdisk command is deprecated: fdisk does not handle GPT partitions. Please use partedUtil

The ESXi operating system is installed on the hard disk:/dev/disks/t10.ATA _____ WDC_WD5000AADS2D00S9B0________________________WD2DWCAV9D135907,

Command I executed: partedUtil delete/dev/disks/t10.ATA _____ wdc_wd5000aads2d00s9b0____________________________wd2dwcav9d135907 1

As a result, partition 1 of the hard disk is lost.

[Root @ localhost: ~] Fdisk-l

Alas, the result is tragic ..................

When the system does not restart, the system can still run normally. I copied important data, but fortunately there are only two virtual machines. The system cannot be started directly after being restarted.
