During the BETA of vSphere 4.1, there were some inconsistencies in some of the build numbers which was eventually resolved. It looks like something was still missed in the final RTM release of vSphere 4.1 ....
Here is a screenshot of the python libraries on classic ESX 4.1 used for esxupdate. At some point, it looks like this release was going to be named vSphere 4.5 as most people had anticipated, but then was revised to 4.1.
I'm sure there will be few more easter eggs, happy hunting 🙂
Continuing from Part1 of new vSphere 4.1 CLI Utilities, here are few more:
1. vmkload_app64 is a 64bit version of the VMkernel application loader.
[root@esx4-1 bin]# /usr/lib/vmware/bin/vmkload_app64 -h
Usage: vmkload_app [options]
--nocore|-n Disable core dump for this world
--enableDebug|-d Enable userworld debug wait after core

(only specify world id when not creating
or connecting to a userworld)
--kill|-k
(only works with vmx worlds)
--ouputCartelID|-o
--setsid|-S Run vmkload_app in a new session

2. vmware-usbarbitrator is a utility for allowing VMs to connect to the host's USB devices.
3. vprobed looks to be a utility for running the vProbe daemon.
[root@esx4-1 bin]# /usr/lib/vmware/bin/vprobed -h
Error: vprobed takes no arguments.
4. vmkiscsiadm was a pretty well known tool used to configure and troubleshoot iSCSI on ESX. However, it has been removed with the release of vSphere 4.1.
5. vmkiscsi-tool has been updated with some new options:
[root@esx4-1 ~]# /usr/sbin/vmkiscsi-tool -h
vmkiscsi-tool -h --help

With the release of vSphere 4.1, we finally get to see the first revision of the vStorage API for Array Integration (VAAI) features. This initial release provides the following SCSI driver primitives with VAAI supported storage arrays:
The above definitions were taken off of an EMC presentation found here. VMware has also published a new VMware KB article regarding VAAI FAQ, take a look here at KB1021976.
Though these features are not specific to any one storage array vendor, the vendors themselves are required to implement these primitives within their array OS software for them to be available. If all prerequisites are met, and you have an ESX or ESXi host running on vSphere 4.1 and VAAI supported storage array, these new storage operations will now offload to the array versus running within the VMkernel.
However, if you do not have an array that supports VAAI, the new version of ESX and ESXi will still try to use these features. As I understand from an earlier discussion of VAAI, there is one additional operation that is performed and it's impact is supposed to be insignificant (please correct me if I'm wrong). Though if you would like to disable these VAAI features or would like to see the difference between a non-VAAI and VAAI operation, it is controlled with the following three advanced host configurations.
VMFS3.HardwareAcceleratedLocking - Atomic Test and Set
DataMover.HardwareAcceleratedMove - Full/Fast Copy
DataMover.HardwareAcceleratedInit - Write Same
By default, all three of these configurations are enabled with a default installation of vSphere 4.1. The following vSphere SDK for Perl script allows a user to enable or disable VAAI configuration on a set of hosts defined in an input file. The script allows you to connect to vCenter if your hosts are being managed by vCenter or directly to a specific ESX or ESXi host and provide the following parameters:
--hostlist = Lists of ESX(i) hosts to perform operation _IF_ they're being managed by vCenter (default is ALL hosts in vCenter)
--operation = Operation to perform (query|enable|disable)
Download: vaaiHWAccelerationMgmt.pl
Here is an example of the host input file:
[vi-admin@makalu scripts]$ cat hosts
esxi4-2.primp-industries.com
esxi4-3.primp-industries.com
