Symantec AppHA doubt

Hi Nayab,

 

APPHA is a high availability product that protects virtual machines against service failures.  It works in VMware virtual machines (Linux and Windows) as well as with HyperV, RedHat Enterprise Virtualization, and others.  

 

APPHA does not protect against disk failures or corruption, its not a traditional clustering product that can protect against say your operating system becoming corrupt, or something similar.  It watches services, daemons, processes and shares/exported mount points to make sure they are working properly.  If they fail, it tries to restart them using various native tools such as service restarts etc.

 

Hope this helps.

Hi ,

 

Thanks a lot for the information in your blog Can help me clarify the things below

 

Thanks a lot for the information above, I have few question hope you are the right person to clarify them.

 

In the AppHA 5.1 version we have seperate options to install Console and AppHA components but in 6.1 i dont see any options like that. Can help me which machine Ip address i need to mention in the screenshots below. Note i am installing AppHA on a VM Windows 2008 machine which i want to use as console.

In the screen shot below i need to mention my Console server IP or I need to key all my VM's IP and hostname ( As i see option Add Multipple Systems next to Browse options ) ?

 

In this screen shot at the configuration TAB it was asked to key-in HA Console IP which means is my HA should be a Remote one and i should install the AppHA on each and every VM machine ? Please confirm.

 

Thanks,

Nayab

Hi Nayab,

 

In screenshot-1:

You can (optionally) specify IPs of other AppHA VMs (i.e. AppHA guest nodes. Not HA Console node) - if you want to install AppHA (guest components) in multile nodes simultaneously.

 

In screenshot-2:

Its asking the IP of HA Console node.

Note that, HA Console can be installed in the same box where AppHA is installed or it can a separate (dedicated) system altogether.

And for an environment (all VMs in a vCenter Server) you need only one HA Console node.

 

Thanks!

Hi Tripathy,

 

Now 

In screenshot-1:

You can (optionally) specify IPs of other AppHA VMs (i.e. AppHA guest nodes. Not HA Console node) - if you want to install AppHA (guest components) in multile nodes simultaneously.

Query :- You mean to say i am pusing the Guest Components by mentioning the IP's of my VM's ?????

Do i need to Push Guest components to my ESXi also ?? Or only my VM's are enough ?

Cross platform was supported i mean i can push the guest components from a Physicsl Windows machine to LINUX VM ?

 

In screenshot-2:

Its asking the IP of HA Console node.

Note that, HA Console can be installed in the same box where AppHA is installed or it can a separate (dedicated) system altogether.

And for an environment (all VMs in a vCenter Server) you need only one HA Console node.

 

Query:- If i key in the IP of AppHA CONSOLE NODE will it install AppHA console  ?? If not at what point during installation i will be installing AppHA console on my server ?

 

Thanks,

Nayab

Hi Tripathy,

 

Do you have any video of Installing AppHA on LINUX Machine ? If any please direct me with link or file.

 

Thanks,

Nayab

Hi Nayab,

 

1)

a) Thats right. You can (optionally) specify the IPs of other VMs, to install AppHA guest component there.

b) No, you don't need to install anything in ESX

c) cross-platform installation is not available.

(Though there is an feature called vSphere Integrated Installation (also known as Push-Install), from where you can install AppHA guest components in both Windows & Linux, from the vSphere Client UI)

 

2) You should install AppHA Console first (before installing AppHA guest components in other VMs).

Then, during AppHA guest installation, it asks for AppHA Console IP (which is already installed), so that it can setup Single-Sign-On (SSO) between the two.

SSO is required for seamless communication between AppHA guests & AppHA Console going forward.

 

I will suggest you to go through the AppHA product docs.

They explain all these in more detail.
