Dell Storage Replay Manager 7.6.0.47 for Compellent 6.5

Recently as a DELL Compellent customer version 7.6.0.47 became available to us. I download it and found some welcome new capabilities in the release notes.

  • Support for vSphere 6
  • 2024 bit public key support for SSL/TLS
  • The ability to retry failed jobs (Microsoft Extensions Only)
  • The ability to modify a backup set (Microsoft Extensions Only)

The ability to retry failed jobs is handy. There might be a conflicting backup running via a 3rd party tool leveraging the hardware VSS provider. So the ability to retry can mitigate this. As we do multiple replays per day and have them scheduled recurrently we already mitigated the negative effects of this, but this only gibes us more options to deal with such situations. It’s good.

The ability to modify a backup set is one I love. It was just so annoying not to be able to do this before. A change in the environment meant having to create a new backup set. That also meant keeping around the old job for as long as you wanted to retain the replays associated with that job. Not the most optimal way of handling change I’d say, so this made me happy when I saw it.

Now I’d like DELL to invest a bit more in make restore of volume based replays of virtual machines easier. I actually like the volume based ones with Hyper-V as it’s one snapshot per CSV for all VMs and it doesn’t require all the VMs to reside on the host where we originally defined the backup set. Optimally you do run all the VMs on the node that own the CSV but otherwise it has less restrictions. I my humble opinion anything that restricts VM mobility is bad and goes against the grain of virtualization and dynamic optimization. I wonder if this has more to do with older CVS/Hyper-V versions, current limitations in Windows Server Hyper-V or CVS or a combination. This makes for a nice discussion, so if anyone from MSFT & the DELL Storage team responsible for Repay Manager wants to have one, just let me know Smile 

Last but not least I’d love DELL to communicate in Q4 of 2015 on how they will integrate their data protection offering in Compellent/Replay manager with Windows Server 2016 Backup changes and enhancements. That’s quite a change that’s happing for Hyper-V and it would be good for all to know what’s being done to leverage that. Another thing that is high on my priority for success is to enable leveraging replays with Live Volumes. For me that’s the biggest drawback to Live Volumes: having to chose between high/continuous availability and application consistent replays for data protection and other use cases).

I have some more things on my wish list but these are out of scope in regards to the subject of this blog post.

Updating Hyper-V Integration Services: An error has occurred: One of the update processes returned error code 1603

So you migrate over 200 VMs from a previous version of Hyper-V to Windows Server 2012 R2 fully patched and life looks great, full of possibilities etc. However one thing get’s back to your e-mail inbox consistently: a couple of Windows Server 2003 R2 SP2 (x64) and Windows XP SP3 (x86) virtual machines. The VEEAM backups consistently fail. Digging into that the cause is pretty obvious … it tells you where to problem lies.

Ah they forgot the upgrade the IS components you might conclude. Let’s see if we try an upgrade. Yes they are offered and you run them … looks to be going well too. But then you’re greeted by "An error has occurred: One of the update processes returned error code 1603”.

Darn! Now you can go and do all kinds of stuff to find out what part of the integrations services are messed up as most day to day operations work fine (registry, explore, versions, security settings …) or be smart a leverage the power of PowerShell. It’s easy to find out what is not right via a simple commandlet  Get-VMIntegrationService

We’ll that’s obvious. So how to fix this. I uninstalled the IS components, rebooted the VM, reinstalled the IS components  … which requires another reboot. While the VM is rebooting you can take a peak at the integration services status with Get-VMIntegrationService

image

That’s it, all is well again and backups run just fine. Lessons learned here are that SCOM was completely happy with the bad situation … that isn’t good Smile.

So there’s the solution for you but it’s kind of “omen” like that it happened to three Windows 2003 virtual machines (both x64 and x86). You really need to get off these obsolete operating systems. Staying will never improve things but I guarantee you they will get worse.

See you at a next blog Winking smile

Windows Server Technical Preview and Hyper-V Server Technical Preview Expiration Extension

Great news for all those of us that are running Windows Server Technical Preview v1 in their labs. It was due to expire on April 15th but Microsoft announced they were working on a fix to extend that deadline. They did not mention an ETA for it bit it’s here now, see http://www.microsoft.com/en-us/download/details.aspx?id=46447

So download, install, reboot and you’re good to go until we get our hands on Technical Preview v2! We’ve been saved by the cavalry and life is good!

Hyper-V Amigos Showcast Episode 8: Storage Replica in a Stretched Cluster

We finally go to make a next “Hyper-V Amigos Showcast”, due to very busy schedules we had to postpone this a couple of times. But we made it! In this Episode (the 8th one) Carsten and I show one application of a new great feature in Windows Server vNext: Storage Replication. This allows us to replicate a volume between two storage systems without caring what that storage system is as long a you have windows volumes on it. Replication can be synchronous or asynchronous and there are multiple scenarios in which to use this.

Here we focus on trying out replication between two clusters or in a stretched cluster scenario. I have already made a video demonstrating server to server replication. In this showcast we demonstrate  the Stretched Cluster scenario (and troubleshoot our own lab).
