Installing SRM–Time Error when connecting to PCS

While installing SRM at a client, I ran into an issue where I could not connected to the PCS.   The setup returned an error stating the time between the vCenter, Site Recovery Server and PCS was not in sync.

 

Image result for multiple time

 

Since the vCenter and PCS were on an Appliance, I had to do some quick research to see how to verify and correct the time.   In this case, the forums had the answer.

 

Enable SSH in the vCenter 6 appliance console
Enable BASH in the vCenter 6 appliance console
Putty in the vCenter 6 appliance
Enter root/PW

Type 'shell'

Enter the following commands:

ls /usr/share/zoneinfo/US/
*  This will display the list of available time zones, in my case I needed Eastern, replace with your time zone
cd /etc
rm localtime
ln -s /usr/share/zoneinfo/US/Eastern localtime
date

* Verify that you are now displaying the correct date and time.
** Optionally you can set the appliance to use an NTP server by using the following command:

sntp -P no -r time.windows.com

In our case, we used the local domain controller for the time source rather then the time.windows.com but it was just a one time set to sync those times up completely.  Once completed, the SRM installer continued without issue.

New Versions of our favorite tools.

Just noticed that some of the tools we (at least I!) love and rely on has been updated. (You can find the complete list here.) From the list of updated ones, I wanted to bring attention to some of the ones that I consider truly indispensable and one in particular that gets very little press.image

· AutoRuns
· Process Monitor
· Process Explorer
· SysMon

I think SysMon is probably the least known from the list above, but maybe one of the most useful. For those who are not familiar, this tool installs very easily from the command line, creates a service, a new EventLog, starts itself up and immediately goes to work. One of the many benefits of the tool is that it installs as a boot-level driver, so it can capture information very early on in the boot process all the way through the logon and beyond.

I like to think of it almost like an Application level WireShark type of tool. It will log every access from your system by any application and tell you the name of the app, what it attempted to do and to where it attempted to do it. I have been able to track down everything from rogue add-ins in Office applications communicating to websites, to performance issues due to over-zealous security applications wreaking havoc on a system. [Ping me if you want to know which one].

To install it, you just run the app with three switches, SysMon.exe -i –n –AcceptEULA

Then launch any application (e.g. Excel) and go to the EventLog (Applications and Services Logs/Microsoft/Windows/Sysmon/Operational) to check out what it really does to your system:

There will be multiple entries for every application depending on what it is doing to your system, so go through the log.

Do you have any particular tool that you find indispensable? Let us know in the comments and we might even review it! Winking smile

P.S. - · AutoRuns is my favorite! (me)  – It’s the quickest way to enable/disable things auto running on your system.  Excellent for cleaning out and tweaking system login times.

Time for a new editor.

I’ve used NotePad++ for a long time.  It’s light weight and doesn’t mess with my line feeds or carriage returns.   I thought I had it all. Smile 

Recently someone on the inter-webs recommended a new editor for use with various code languages.  Atom by Github

image

I don’t program full time so this might be old news to everyone reading this but for me, this was a great find and suggestion.   It is completely open source (hosted up on github) so errors, bugs and enhancements are rolled out pretty rapidly due to a highly active community.

The thing I like most about it is the packages you can download for it.  It can pretty much be customized for anything you like. Write yaml? Install a real-time linter into the editor.  Work with Powershell, there are syntax highlights for that as well.  In fact, pretty much every little language/syntax/highlighter I wanted to work with, I found in the community.  AutohotKey, no problem.

I’m not saying this is better than the editor you use, I just liked it so much that I wanted to pass along the great suggestion given to me.  If you are looking to change things up, check it out. Smile

VMware HA Heartbeat issue.

This is a pretty standard one.  You deploy a small environment that only has a single shared Datastore (like a Nutanix cluster maybe).  Enable HA and all of a sudden all of the hosts are complaining that there is only one Datastore for heartbeating and the required minimum is 2.

image

That’s an easy one to resolve. There’s an advanced setting that allows you to safely ignore this warning and turn your console back to the error free goodness that it once was.

Fire up Google and find this KB article.  (https://kb.vmware.com/kb/2004739) because I can never remember the exact parameter.  Awesome. Fire up the VI Client and go to advanced options.

image

Ummm???  Where the hell is advanced options??  It was always been here.

Not anymore.  To access advanced options, be sure to fire up the WEB CLIENT.  I’m not sure when they made the change but with the 6.0 vSphere Fat Client, advanced options are no longer there.

Once you are in the RIGHT client though, the fix is again pretty easy.

image

If you are still using the Windows Client as a crutch, start using the web client.  eventually, you won’t have a choice. Smile

Veeam Backup and Data Domains

If you are running Veeam and using a Data Domain as a backup target, there are a few options in the Veeam configuration that might not seem obvious that can really improve your backup times and windows.

When creating your Data Domain repository in Veeam, be sure to decompress the blocks before writing them to data domain.  This tells Veeam to store raw files and allow the Data Domain to leverage it’s hardware and algorithms to achieve the highest compression.

image

Under individual Job options, you should also disable inline data deduplication to allow the Data Domain to do a superior job at deduping the data.

image

Dedupe-friendly compression level and also local target are also advised for Data Domains.

If your Data Domain has a DD Boost license, you can leverage that on the repository to further increase performance and optimization.

For detailed Veeam write up, refer to https://www.veeam.com/kb1956

BTW: Happy New Year! Took the last few months off from the blog but back on the horse although, You might will see a lot more posts on Home Automation. Consider yourself warned!
