Steps for vCenter 6.0 Appliance Deployment

Mount the vCenter appliance 6.0 DVD and run the vcsa-setup.html file

Click on Install

 

Accept license agreement and click on “Next”

Enter the root credential of our esx host

Accept the certificate of esx host

Give a name for virtual appliance

In this lab scenario, we are going to install psc & vc in two different virtual appliances

Assign sso password, ssodomain name and Sso site name

Click on Next

Select datastore to install virtual appliance.

Assign an IP address, fqdn and other network related details.

Click on Next

Click on finish

Now we can start vcenter server appliance deployment. Process is same as as psc deployment

Enter our platofrm service controllers fqdn and sso administrator credential

Select the appliance size

Select the datastore for deployment

We are going to use embedded database(postgresql)

Click on finish

Once finish the installation, we can use vcenter fqdn or ip address to manage our vcenter

Call ïscsimanager.query candidatenics"

In my lab environment I used iscsi as my shared storage. Today I have removed network adapters from software iscsi adapter to do some other networking stuff. After a while when im trying to reconfigure iscsi im getting below error

Call ïscsimanager.query candidatenics”

To resolve this problem I had to reset iscsi from esx shell by following below steps

Logged to the esx host & find iscsi related config files

Raw Device Mappings

What is raw device mapping?

Raw device mapping is a feature where the virtual machine can directly access the storage devices such as SAN or DAS.

With a VMware we will use vmdk pointer to provide the proxy facility to raw device.

In a virtual environment some cases we may need to have a raw device mappings.

Why we need raw device mapping?

• To configure Microsoft failover cluster, we can configure raw device as shared storage.
• When we are configuring Microsoft failover cluster with one node is running on as a VM & other node/s running as a physical.
• To run some of the san management software(ex hitachi horcm)
• To run some backup software on virtual machine, and needs to get storage level backup

How to Configure?

1. Here I have one vm which is prepared to mount raw device



1. Using new datastore adding procedure, we can see new lun which is provided from our shared storage(in my case im using windows iscsi server)

VMware V6-ESX Password Policy

With earlier version to manage password policies we have to edit /etc/pam.d/passwd file,

But with the vsphere 6 , once we open the file we can see below output.

Its saying we have to use esx host advanced configuration for that.
