ESXi 手動刪除磁區
某些時候你將磁碟加入成為DataStore時，可能會出現錯誤：
A specified parameter was not correct. vm.Host.DiskPartitionInfo.spec ... ...
意指你加入的磁碟可能已經有其他分割無法進行刪除成為DataStore，會有這狀況可能是ESXi使用fdisk指令來管理磁碟，在你的分割是GPT或是fdisk本身無法管理的都會出現類似的錯誤，所以你必需要使用其他指令進行手動刪除。
partedUtil
使用ssh登入ESXi Server時，執行partedUtil不加參數會出現指令的使用方法：
Usage: Get Partitions : get <diskName> Set Partitions : set <diskName> ["partNum startSector endSector type attr"]* Delete Partition : delete <diskName> <partNum> Resize Partition : resize <diskName> <partNum> <start> <end> Get Partitions : getptbl <diskName> Set Partitions : setptbl <diskName> <label> ["partNum startSector endSector type/guid attr"]* Fix Partition Table : fix <diskName> Create New Label (all existing data will be lost): mklabel <diskName> <label> Show commonly used partition type guids : showGuids Get usable first and last sectors : getUsableSectors <diskName> Fix GPT Table interactively : fixGpt <diskName>
稍後會使用Delete Partition : delete <diskName> <partNum>進行刪除。
尋找磁區
刪除磁區前首先尋找該磁區的磁碟名稱：
ls -l /vmfs/devices/disks
所以與磁碟、磁區有關的都會在disks這目錄內，使用ls -l列出很多資訊

以t10.開頭的主要是你機器上的磁碟，以例子中要找的是EZLINK T34這個256GB SSD，它先前在windows使用過，所以要進行手動刪除才能成為DataStore，重新執行指令將所有EZLINK T34的都列出來：
ls -l /vmfs/devices/disks/t10.ATA_____EZLINK_T34_256GB*
列出相關的：
-rw------- 1 root root 256060514304 May 16 15:16 t10.ATA_____EZLINK_T34_256GB________________________201410300108________ -rw------- 1 root root 367001600 May 16 15:16 t10.ATA_____EZLINK_T34_256GB________________________201410300108________:1 -rw------- 1 root root 255158087168 May 16 15:16 t10.ATA_____EZLINK_T34_256GB________________________201410300108________:2 -rw------- 1 root root 532676608 May 16 15:16 t10.ATA_____EZLINK_T34_256GB________________________201410300108________:3 /dev/disks # ls -l t10.ATA_____EZLINK_T34*
其他名稱後面以:冒號與數字組合的名稱為磁區，以這個列表看來總共分割成3個磁區，現在要一一的將三個磁區刪除。
刪除磁區
承上已經列出要刪除磁碟資訊：
t10.ATA_____EZLINK_T34_256GB________________________201410300108________ -rw------- 1 root root 367001600 May 16 15:16 t10.ATA_____EZLINK_T34_256GB________________________201410300108________:1 -rw------- 1 root root 255158087168 May 16 15:16 t10.ATA_____EZLINK_T34_256GB________________________201410300108________:2 -rw------- 1 root root 532676608 May 16 15:16 t10.ATA_____EZLINK_T34_256GB________________________201410300108________:3
此時利用partedUtil的Delete Partition : delete <diskName> <partNum>進行刪除：
cd /vmfs/devices/disks
partedUtil delete "t10.ATA_____EZLINK_T34_256GB________________________201410300108________" 3 partedUtil delete "t10.ATA_____EZLINK_T34_256GB________________________201410300108________" 2 partedUtil delete "t10.ATA_____EZLINK_T34_256GB________________________201410300108________" 1
以上執行正確後，重新再查看一下時，應該會看到只剩磁碟名稱：
ls -l /vmfs/devices/disks/t10.ATA_____EZLINK_T34_256GB*
結果：
-rw------- 1 root root 256060514304 May 16 16:04 /vmfs/devices/disks/t10.ATA_____EZLINK_T34_256GB________________________201410300108________
確定刪除後就可以利用vSphere Client進行重新加入成為DataStore的動作。
