If you are in the unfortunate position in which you or someone else has forgotten the vCenter SSO v5.1 [email protected] password, then you may have a problem. Particularly if there are no other users delegated as SSO administrators.
However the aim of this blog post is to help you in resetting the [email protected] password in SSO 5.1 only (it is much easier in 5.5)!.
First and foremost it's worth pointing out this is completed unsupported by VMware. VMware's advise and supported method is to reinstall SSO.
However you do have 2 other possible options I have presented below.
The default pathing policy for a LUN can be changed (for example from Fixed to Round Robin). This can be a LUN on an iSCSI or FC array (or FCoE for that matter).
When I refer to pathing policy I'm refering to what you may have seen if you've ever clicked manage path's on a VMFS datastore and see it set to Fixed, Round Robin (RR) or Most Recently Used (MRU).
In this example I will be changing the default pathing policy for an EqualLogic array from Fixed to Round Robin.
Before I get into how to change the multi-pathing policy, it's important to understand the below 3 plugins (NMP, SATP and PSP):
Since the release of VMware Horizon View 5.2 Feature Pack 1, it has been possible to access View virtual desktops simply via a HTML5 browser, without the need for the View Client.
Now in Horizon View 5.3 Feature Pack 1, this ability now has an improved feature set and really makes this a viable alternative in some cases to the full VMware View Client. It is particularly useful if you need to get access to a desktop quickly where the View client is not installed or cannot be installed, such as working remotely on a non company owned device.
Some of the improvements to functionality are:
I just had an issue with vCenter 5.5 and ESXi 5.5 where I was unable to power on a VM.
The error which I was faced with was a relatively generic message based on the host connection status.
"The operation is not allowed in the current connection state of the host"
In part 1 and 2 we covered the installation of the pre-requisite's required for SCCM and the actual install of SCCM.
In this part (part 3) we will perform the post installation tasks for SCCM.
We are going to cover checking the publishing status to Active Directory, Network access account, Software update syncing from Microsoft, Email alerts and network boundaries.
In this blog post I will go through the installation of System Center Configuration Manager 2012 R2 as a single Primary Site Server.
SQL Server 2012 is installed on the same server which SCCM will be installed on, which itself will be Windows Server 2012.
You can install SQL Server 2012 on the same server as SCCM or on a seperate server if you wish, If you are yet to install SQL Server 2012 you can view the step by step process for that here SQL Server 2012 Install Step by Step.
In part 1 we covered the installation of the pre-requisite's required for SCCM. If you missed that catch it below, otherwise we will get on with the install of SCCM 2012 R2.
SCCM 2012 R2 Installation
1. Run the SCCM 2012 R2 Setup (splash.hta) and Click "Install"
I recently had a problem in my home lab where I had forgotten the password to my 3COM 2928 SFP Plus switch. So I was unable to logon to the web administration page to configure the ports.
As I understand it, if you do not know any usernames/passwords for the switch your only option is to perform a factory reset, losing ALL configuration from the switch. So hopefully you have an up-to-date backup of the config to re-apply, or it was a simply setup you can remember. You need to do this out of hours if it's in production!
Note: The default password for a 3COM 2928 SFP (I assume its the same all the 2900 series and some other 3COM switches):
Like many in the UK when they found out they could get superfast BT Infinity fibre optic broadband, I signed up right away. The fast speeds of upto 76mb down and 19mb up were too good to miss out on, particularly with the remote work for customers I do and lots of home working in my lab.
However I also did not realise that with the change from ADSL broadband to fibre optic broadband (BT Infinity), it meant [apparently] that the router (BT Home Hub and modem) could only be connected to the master socket.
I recently came across a vCenter/Update Manager server which had been built whilst been joined to one domain. Then later it has been removed from that domain and joined to a different one.
i.e. from "something.local" to "managed.something.com"
As such VMware vSphere Update Manager has not been reconfigured as was not working correctly (even though the service was running), giving the following errors:
"Plug-in is unavailable for the following server(s) : server.something.local"
"There was an error connecting to VMware vSphere Update Manager [server.managed.something.com]"
"The request failed because the server name 'server.something.local' could not be resolved"
Windows To Go is an enterprise feature of Windows 8 and is quite simply the Windows 8 operating system installed onto a USB drive which potentially can be run from any computer which supports it.
When you create a Windows To Go drive, your installing the Windows 8 Enterprise operation system onto the USB drive, which then on top of you can install drivers, applications, customisation, join to a domain etc.
This article covers the creation of a Windows To Go workspace with System Center Configuration Manager 2012 SP1 (SCCM).
We will use an existing boot image, operation system image and task sequence in SCCM, that is being used to deploy physical desktops.
You will need a certified Windows To Go USB key of 32GB or greater in size, I found I needed a 64GB key for the extraction space (not any old USB key will suffice it needs to be a certified one).
More info can be found here http://www.microsoft.com/en-gb/windows/enterprise/products-and-technologies/devices/windowstogo.aspx
A Windows To Go drive is achieved in two phases:
Phase 1 - Create Pre-Staged Media
Phase 2 - Create Windows To Go Workspace USB key from Pre-Staged Media
1. Open Configuration Manager and browse to your task sequences
2. Right click a task sequence and select "Create Task Sequence Media"
