[MVS]ESXi创建datastore报错Fail to create VMFS datastore解决方法

错误现象：

在VMware vShere/ESXi中创建新的数据仓库datastore时，弹出错误提示！“Fail to create VMFS datastore VMFS xxxx”- cannot change the host configuration."

原因猜测：

该硬盘被其他系统格式化为特定分区；

处理过程：

### 查看磁盘分区表报错；

[root@ESXi149:~] partedUtil getptbl /vmfs/devices/disks/naa.600062b20e7016402f3c77bfba1c2865

Error: Input/output error during read on /dev/disks/naa.600062b20e7016402f3c77bfba1c2865

Error: The primary GPT table states that the backup GPT is located beyond the end of disk. This may happen if the disk has shrunk or partition table is corrupted. Fix, by writing backup table at the end? This will also fix the last usable sector appropriately as per the new reduced size. diskPath (/dev/disks/naa.600062b20e7016402f3c77bfba1c2865) diskSize (62499995648) AlternateLBA (62499999743) LastUsableLBA (62499999710)

Warning: The available space to /dev/disks/naa.600062b20e7016402f3c77bfba1c2865 appears to have shrunk. This may happen if the disk size has reduced. The space has been reduced by (4096 blocks). You can fix the GPT to correct the available space or continue with the current settings ? This will also move the backup table at the end if it is not at the end already. diskSize (62499995648) AlternateLBA (62499999743) LastUsableLBA (62499999710) NewLastUsableLBA (62499995614)

### 执行提示命令错误

[root@ESXi149:~] partedUtil setptbl /vmfs/devices/disks/naa.600062b20e7016402f3c77bfba1c2865

### 执行提示报错，超出磁盘范围；

### 使用DD清楚磁盘格式

[root@ESXi149:~] dd if=/dev/zero of="/vmfs/devices/disks/naa.600062b20e7016402f3c77bfba1c2865" bs=512 count=34 cOnv=notrunc

### 可查看分区情况了；

[root@ESXi149:~] partedUtil getptbl /vmfs/devices/disks/naa.600062b20e7016402f3c77bfba1c2865
