Gen8上的ESXi折腾纪录(硬盘篇)

留下纪录，以备查验，走了不少弯路啊

首先说一下，Gen8 的内置的软 RAID 支持单块硬盘初始化成 RAID0 使用的，也就是说，单块硬盘也可以开 RAID 模式，然后在 ilo 里面就可以看到硬盘信息了，并且内置的 RAID 支持识别 HDD 和 SSD，初始化过后，在 ESXi 里面也可以正常识别为 SSD。

一开始用 ACHI 模式在 ESXi 好像很卡？

然后切换到了 RAID 模式，直接切换后会识别不到硬盘，必须去 RAID 的控制器初始化一下，也就是 POST 的时候看见 F5 就按一下 F5 进去。
切换到 RAID 模式之后，在 vSphere 添加硬盘竟然出现了错误！！

调用对象 “ha-datastoresystem”的“HostDatastoreSystem.QueryVmfsDatastoreCreateOptions” 失败

这不是坑爹么……

多方查验，出现这个问题是因为磁盘上有不支持的分区格式，我去，写的明明是使用整块磁盘，您不能重新初始化一下分区表吗

网上的解决方法，来自ESXi5.1 调用对象”ha-datastoresystem”出错及处理虽然我装的是 ESXi6 但是按照这个解决了，就是开 SSH 进去用 fdisk 删除了分区。

记录一下方法，避免原作者网站消失……

1、查看磁盘情况

[root@Gen8-ESXi:~] fdisk -l

（这是后来加了一块 SSD 到 SATA5 之后出错的信息，套用一下，之前没保存）

2、删除磁盘分区(注意一定要分清楚磁盘编号，别删错了)

[root@Gen8-ESXi:~] fdisk /dev/disks/naa.600508b1001cd4c1eeb69635def8f132

Command (m for help): d

Command (m for help): 1
1: unknown command
Command Action
o   create a new empty DOS partition table
p   print the partition table
q   quit without saving changes
s   create a new empty Sun disklabel

Command (m for help): o
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that the previous content
won't be recoverable.


The number of cylinders for this disk is set to 7264.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table

然后现在就可以正常的添加硬盘了~:smiley:
