Another one of those posts today that most likely will not affect most, however there is a known issue with the vStorage APIs for Array Integration (VAAI) mixed together with EMC VMAX Storage Arrays. My best bud, Chad Sakac, wrote about this last week ().
Long story short, if you’re running a VMAX with Enginuity
along with ESX(i) 4.1 hosts you may see some slowness when trying to do things like Storage vMotion, Deploy from Template, etc…basically things that leverage HardwareAcceleratedMove.
So how do you fix it?
First thing is you need to disable HardwareAcceleratedMove, instructions on how to do this can be found in . Next thing is to contact EMC Support and have the ePack that engineering released for this problem installed on your VMAX. Then finally, contact VMware support for their hotfix…rumor has it that a VMware support bundle should be released sometime soon. After you have the patch for VMAX as well as vSphere you should have no problem turning HardwareAcceleratedMove back on.
So to wrap this up….VAAI issue when mixed with VMAX, but it doesn’t affect all VAAI functionality, just XCOPY (HardwareAcceleratedMove) and even then it doesn’t affect every single operation. Get the patches, get them installed and get back on schedule!

In a very random situation that most customers probably wouldn’t even encounter, we’ve came across a bug while importing an OVF that has a VMDK with a SCSI Address of X:15 (ie: SCSI 0:15, SCSI 1:15, etc). It appears that vSphere doesn’t take kindly to virtual machines being imported that have virtual disks addressed as X:15 and will issue the fatal error “Unsupported value  for element ‘addressOnParent’. I’ve tested this with different SCSI Adapters thinking it was perhaps tied to LSI Parallel, this was not the case as it failed with all other adapters.
This issue actually came up initially while attempting to import an OVF into a Catalog within vCloud Director. A similar error appears stating “The following error was encountered while processing the OVF file you provided: Unsupported value  for element ‘addressOnParent’.”
You can see the offending line within the actual OVF file shown below, this is tied back to the actual VMDK and what SCSI Bus it resides on, as shown in the picture below the OVF file.
I’ve raised the question to VMware Engineering and will hopefully be able to post their response to this issue shortly.

vmware has recently released a patch for their vSphere 4.0 product line, which affects both ESX and ESXi.
Details from vm
We are pleased to inform you that a new VMware ESX 4.0 Patch is available as of April 28, 2011.
Improvements included in this patch:
Detailed information regarding resolved and known issues and enhancements can be found at ESX 4.0 Patch Release Notes
VMware ESX 4.0 Patch is available for download at:
Download VMware ESX 4.0 Patch .
VMware vSphere Product Management Team
One of the patches included (ESX400--SG for ESX and ESXi400--SG for ESXi) resolves a couple different issues, one updates the Certification Revocation List (CRL) to revoke a key that HP uses for code-signing certain software components. HP server contains a new key pair and has re-signed the affected software components with the new key. What this means is that if you apply this patch on a HP server and you are using specific HP management agents (like the HP Management Agent for VMware ESX 4.x) you will need to download the software with the updated key and re-install it.
The other fix within the above mentioned patch resolves a potential denial of service attack against the vmkernel over it’s management interface. When an attacker exhausts all available sockets the ESX(i) host will become inaccessible via vCenter or the vSphere client. Virtual Machines will continue to run and have network connectivity, but the ESX(i) host may need to be rebooted in order to be able to connect to the machine again. The ESX(i) system might intermittently lose connectivity caused by applications that do not correctly close sockets. If this occurs, an error message similar to the following might be written to the vpxa log file:
socket() returns -1 (Cannot allocate memory)
An error message similar to the following might be written to the VMkernel log file:
socreate(type=2, proto=17) failed with error 55
The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name
to this issue. More information on this patch can be found in
Another patch, specific to ESXi (ESXi400--BG), has also been released. The only information on this patch can be found in
which states “This patch improves the way shared folders are handled.”.

vmware Labs has released vCenter XVP Manager and Converter, their first stab into management of non-VMware virtualized environments. vCenter XVP Manager allows you to use the vSphere Client to manage Hyper-V Server 2008 hosts and their associated virtual machines, it also allows you to easily migrate those Hyper-V based virtual machines into VMware virtual machines.
The installation is pretty simple, you first install a server piece that could very well be installed on your vCenter Server, then you install a XVP Manager Plug-in into your vSphere Client which is done via the vSphere Client Plug-in Manager.
This product is currently only listed as a vmware Labs Fling, which means that it is not guaranteed that it will continue beyond it’s 1.0 Technical Preview status, but if people like it and push vmware for this type of functionality we may very well see it embedded within the core vCenter Server product.
For more information and to download vmware vCenter XVP Manager check out the vmware Labs .

VMware vSphere 5.0存储新功能解析
VMware vSphere 5.0存储新功能解析
来源： 存储在线 日
借由改进的VMFS档案系统、VAAI API、虚拟机迁移功能，以及配套的SRM与VSA等经过改进或全新的套件，vSphere 新版可提供更具扩展性、更有效率、管理也更简单的存储服务。- 强化效能：可搭配整合在VAAI架构中的ATS(Atomic Test &Set)功能，当存储设备支持VAAI时，可利用存储硬体加速file locking效率。
借由改进的VMFS档案系统、VAAI API、虚拟机迁移功能，以及配套的SRM与VSA等经过改进或全新的套件，vSphere 新版可提供更具扩展性、更有效率、管理也更简单的存储服务。
刚发布的vSphere 5.0,是VMware数据中心级 ESX虚拟化平台家族的第5代产品，相较于上一个版本，VMware宣称vSphere 5.0拥有200多项功能更新，其中在存储部份，提供了改进的VMFS档案系统，更方便的属性驱动存储(Profile-Driven storage)与Storage DRS功能，还可搭配与vSphere 5.0一同发布、用于提供共享存储服务的vSphere Storage Appliance(VSA)套件，另外与vSphere搭配的SRM自动化灾难复原管理套件，也新增了内置远端复制功能，借由这些改进与新增功能，可为用户的虚拟化环境，提供扩展性更大、更弹性、管理更方便的存储服务。
扩展性更大的VMFS-5档案系统
VMFS档案系统(VMware Virtual Machine File System)是VMware虚拟化平台存储架构的基础，迄今共衍生了4个世代，VFMS-1是搭配ESX 1.x平台，VFMS-2用于搭配ESX 2.x平台，ESX 3.x与vSphere 4.x平台都是采用VMFS-3,vSphere 5.0则搭配新的VMFS-5。
最新的VMFS-5有几项改进：
- 更弹性的区块(block)设定：先前的VMFS使用1MB、2MB、4MB、8MB大小的区块，越大的档案将对应更大的区块，如1MB区块只能支持最大256GB的档案，8MB区块则能支持2TB的档案。VMFS-5则解除了这些限制，即使非常大的档案，也能使用1MB区块。
- 更大的磁盘区：先前版本VMFS支持的单一extent Volume,最大为2TB,VMFS-5则提高到64TB,可利用大于2TB的LUN来建立单一extent Volume.
- 在RDM pass-through(Physical Compatibility)模式下，允许超过60TB大小的LUN;不过非pass-through的RDM模式(Virtual Compatibility)的LUN最大仍为2TB.
- 支持GPT分割：随着支持的磁盘区容量大幅提高，VMFS-5采用了GUID分割表借以支持大于2TB的分割区(先前版本VMFS采用的MBR分割，有2TB容量上限)。
- 更好的小档案支持：先前版本VMFS的子区块(Sub-Block)为64KB,VMFS-5则改为8KB,存放小档案时的容量效率更佳，对于大于1KB、小于8KB的档案，只会占用8KB子区块，不像先前版本是从64KB起跳，可节省许多空间。对于小于1KB的档案，VMFS-5则使用metadata来描述档案位址，不使用档案区块，亦可减少容量消耗。
- 可容纳更多档案：每个Volume允许存放超过10万个档案，较先前增加3倍(VMFS-3是30,720个)。
- 强化效能：可搭配整合在VAAI架构中的ATS(Atomic Test &Set)功能，当存储设备支持VAAI时，可利用存储硬体加速file locking效率。
不过VMFS-5允许的最大VMDK档案大小仍为2TB,每台ESXi主机允许使用的LUN也与先前同样都是最大256个。既有VMFS-3可在线上直接升级为VMFS-5,而不会影响虚拟机运行。
效率更高的Storage vMotion
Storage vMotion可将虚拟机从一台存储设备迁移到另一台存储设备，而不会造成虚拟机服务的中断。这个功能出现的其实相当早，但最初并不是叫做Storage vMotion,而是一种升级工具，用于协助用户将虚拟机从ESX 2.x平台迁移到3.0.1,也就是从VMFS-2档案系统存储区迁移到VMFS-3存储区。
到了ESX 3.5时，则引进了透过快照(snapshot)辅助迁移的机制，在执行虚拟机迁移过程中，可利用虚拟机的快照复本来处理迁移期间的I/O,当迁移完成后，再将异动数据从快照复本，写进搬移到新位置的虚拟机中。
在vSphere 4.x上，Storage vMotion舍弃了利用虚拟机快照作为中继辅助的作法，改透过新增的异动区块追踪(Changed Block Tracking)功能，来记录虚拟机复制迁移期间的数据异动，可减少迁移后所需写入的异动数据量。
到了最新的vSphere 5.0,Storage vMotion引进了称为Mirror Mode的新模式，可透过镜像复制方式，以single pass block copy一次将所有要迁移的区块从来源端复制到目标端，可缩短迁移作业耗费时间。至于开始迁移作业后才在来源端产生的区块异动，则利用新的镜像驱动程式(Mirror Driver)将异动区块从来源端同步到目标端，让来源端与目标端在复制过程中保持一致(当来源端Guest OS要对已经被Storage vMotion复制到目标端的区块进行写入动作时，Mirror Driver会立即将这个写入I/O也同步到目标端)。
除迁移程序上的改进外，vSphere 5.0的Storage vMotion还有两项新功能，一是可以搭配拥有快照或Clone复本连结的虚拟机运作，可同时搬移虚拟机本体与其连结的快照/C另一是可搭配针对存储端的负载平衡功能运作，依负载情况自动在不同存储设备间迁移虚拟机，也就是Storage DRS(Distributed Resource Scheduler)功能。

让我们了解一些常见的Linux shell命令。这些命令并非ESXi的专用命令，你会发现很多命令也可以在大多数的Linux发行版中使用。
来源：TechTarget中国
vCenter Server一直是管理VMware环境的主要工具。尽管通过vCenter Server执行变更及修改操作具有诸多优势，但在每个VMware管理员的职业生涯中难免会遇到vCenter无法使用的情况。vCenter不可用时，使用vSphere client直接连接主机能够在很多方面帮到你，但仍旧有很多任务无法完成。
排除故障时，知道如何使用ESXi shell至关重要，而且对常见的Linux命令以及ESXi命令有一个基本的了解对你来说永远都不是什么坏事儿。
Linux shell命令
首先，让我们了解一些常见的Linux shell命令。这些命令并非ESXi的专用命令，你会发现很多命令也可以在大多数的Linux发行版中使用。
find/cat/grep&&在试图查找指定的文件或者在某个文件中查找字符串时这三个命令非常重要。find命令可以基于文件名或者模式查找指定的文件，cat命令用于显示文件内容，grep用于在单个或多个文件内查找指定的字符串。
find /path/to/vm/folder &i name "*delta*" & 列出虚拟机所有的增量磁盘。
cat hostd.log | grep error &在hostd.log中查找所有的"error"字符串
head/tail&&查看文件内容时这两个命令非常有用。尽管可以使用cat命令显示文件完整的内容，但head以及tail命令可以用于显示文件开头或结尾的部分，忽略了文件的中间内容。进行故障诊断时tail命令尤为有用，尤其是可以使用-f标记实时监控日志文件发生的变化。
tail -f /var/log/vmkernel.log & 实时查看vmkernel日志发生的变化
less&&显示大文件内容时less命令非常有用。通过在cat命令的输出内容之后输入&|&less,可以分页显示输出结果，而且可以向前或向后滚动浏览。
cat /var/log/vpxa.log | less &在屏幕上分页显示vpxa.log文件的内容。
df/vdf&&这两个命令显示文件系统的可用空间。df命令显示本地文件系统以及数据存储的容量、已用空间以及可用空间。为查看ESXi主机不同随机磁盘的使用情况，必须使用vdf命令。这两个命令都可以用于发现由于可用空间不足而可能导致的任何问题。
ps/kill&&这两个命令分别用于查找ESXi主机内部运行的服务、强制终止这些服务。ps命令包括很多命令行开关，但最常用的是检索正在运行的进程的ID，然后就可以使用Kill命令终止相应的服务。
vi & 如果之前不熟悉vi命令，那么在学习时大多会遇到麻烦。Vi是一个文本编辑器，用于修改文件内容&vSphere管理员通过命令行shell进行故障诊断时必须要具备该技能。
ESXi专用命令
接下来让我们了解一些在ESXi命令行shell下最常用的命令。这些ESXi命令不仅能够帮助你进行故障诊断，还可以用于日常维护以及性能监控。
services.sh&& Linux服务通常使用services命令管理，管理ESXi服务是通过使用services.sh命令实现的。Services.sh命令支持的参数包括stop、start、restart，通过这三个参数可以停止、启动或重启所有的ESXi服务。
services.sh restart & 重启所有的ESXi服务
/etc/init.d&& 执行位于/etc/init.d目录下的脚本可以启动或停止对应的服务。如果只想重启vCenter Server Agent（vpax服务），可以运行/etc/init.d/vpxa restart 命令。而services.sh restart将重启所有服务。
/etc/init.d/vpxa restart & 重启主机上的 vCenter Agent&
cat /etc/chkconfig.db & 查看所有ESXi服务的运行状态。
vmkping&&我们都熟悉ping命令的用法及功能。Vmkping命令更进一步，允许使用Vmkernel的IP堆栈通过特定的接口发送ICMP数据包。这意味着你可以通过vMotion网络而非管理网络发送ping包。
vmkping &I vmk1 10.10.10.1 & 通过vmkl接口向10.10.10.1发送ICMP请求
nc&&组合使用vmkping、nc命令（netcat），可以确认ESXi主机与特定IP之间的网络连通性。尽管vmkping命令通过ICMP确认连通性，但有时我们想确认是否可以访问特定的TCP端口(例如iSCSI的TCP端口是3260)。
nc &z 10.10.10.10 3260 & 测试是否能够访问10.10.10.10的3260端口。
Vmkfstools-如果需要通过命令行管理VMFS数据卷以及虚拟磁盘，那么vmkfstools命令就派上用场了。使用vmkfstools命令可以创建、克隆、扩展、重命名并删除VMDK文件。除了虚拟磁盘选项，你还可以使用vmkfstools命令创建、扩展、增大、回收文件系统的数据块。
vmkfstools&&i test.vmdk testclone.vmdk & 将test.vmdk克隆为testclone.vmdk
esxtop&&对ESXi主机进行性能监控以及故障诊断时，很少有工具能够提供和esxtop同样多的信息。除提供和Linux top命令类似的功能外，esxtop还可以收集很多VMware专有的指标，包括中断、内存、网络、磁盘适配器、磁盘设备以及电源管理。
vscsiStats&& 需要进一步监控存储I/O的性能时，vscsiStats命令就能够派上用场了。vscsiStats命令能够帮助你收集与虚拟机磁盘I/O负载相关的性能数据。进行容量规划或者迁移后端存储时，使用vscsiStats命令收集到的数据可谓价值连城。
vim-cmd&&vim-cmd是构建在hostd进程之上的命令空间，允许最终用户调用几乎所有的vSphere API。Vim-cmd提供了一些ESXi子命令管理不同的虚拟基础设施，而且和vimsh相比，更容易使用。
dcui &登录到ESXi主机时，VMware直接用户控制台接口（DCUI）提供了基于菜单的主机管理功能。DCUI提供了很多不同的功能，比如root密码维护、网络维护。有时你可能只能通过SSH访问主机，但幸运的是，在命令行下执行dcui命令就可以进入基于菜单的DCUI系统。
vm-support&&曾经想过收集ESXi主机所有的支持及日志信息吗？Vm-support命令恰好能够满足你的要求。如果之前与VMware的技术支持热线联系过，那么很可能用过这个命令。
esxcli命令探究
esxcli命令用途广泛，我们不能简单地将其归为单个命令。esxcli包括许多不同的命名空间，允许你控制ESXi提供的几乎所有设备。下面列出了使用最频繁（肯定不是所有）的命名空间：
esxcli hardware&& 想获取ESXi主机的硬件及配置信息时，esxcli硬件命名空间就能够派上用场了。
esxcli hardware cpu list & 获取CPU信息（系列、型号以及缓存）
esxcli hardware memory get & 获取内存信息（可用内存以及非一致内存访问）
esxcli iscsi&& iscsi命名空间可以被用于监控并管理硬件iSCSI及软件iSCSI设置。
esxcli iscsi software &用于启用/禁用软件iSCSI initiator。
esxcli iscsi adapter &用于设置软硬件iSCSI适配器的发现、CHAP以及其他设置
esxcli iscsi sessions & 用于列出主机上已建立的iSCSI会话。
esxcli network&&需要监控vSphere网络并对如下网络组件进行调整时，包括虚拟交换机、VMkernel网络接口、防火墙以及物理网卡等，esxcli网络命名空间就派上用场了。
esxcli network nic &列出并修改网卡信息，比如名字、唤醒网卡以及速度。
esxcli network vm list & 列出有一个活动网络端口的虚拟机的网络信息。
esxcli network vswitch &检索并管理VMware的标准交换机以及分布式虚拟交换机。
esxcli network ip & 管理VMkernel端口，包括管理、vMotion以及FT网络。还可以修改主机的所有IP栈，包括DNS、IPsec以及路由信息。
esxcli software&& 软件命名空间可以用于检索ESXi主机已安装的软件及驱动并可以安装新组件。
esxcli software vib list & 列出ESXi主机上已经安装的软件及驱动。
esxcli storage&& 可能是最常用的esxcli命令命名空间之一，包括了管理连接到vSphere的存储的所有信息。
esxcli storage core device list & 列出当前存储设备
esxcli storage core device vaai status get &获得存储设备支持的VAAI的当前状态。
esxcli system&& 通过该命令使你能够控制ESXi的高级选项，比如设置syslog并管理主机状态。
