VMware SRM – Failed to Sync data on Replica Devices

I came across an interesting situation when performing a Test recovery using VMware SRM, I received the following error:

I performed a quick google to try to find a solution to the error message but there wasn’t anything listed, the only suggested solution I could find was to uninstall VMware SRM, reinstall it using a new database… this was not a solution with a looming Disaster Recovery Test and therefore I thought that I would try to correct the issue myself.

The configuration I have utilises IBM XIVs with Storage Array replication although I believe that the same steps should still work for other arrays.

  • Remove all disks from the consistency group experiencing this error
  • Deactivate the mirror on the consistency group and then delete the mirror pair
  • Delete the consistency group on both the source array and the destination array
  • Create a new consistency group on both the source and destination arrays
  • Create a new mirror pair for the consistency group that has just been created
  • Activate the new mirror pair and make sure that they are synchronised
  • Add the required LUNs to the newly created consistency group
  • Rescan the SRAs in the SRM client several times to update the connections, this may not update correctly the first time
  • Check that all of the LUNs in the consistency group have an arrow against them indicating the replication direction on both the source and destination arrays within SRM
  • Go to your recovery plan and perform a test recovery

About the Author


I have been in IT for the past 15 years and using virtualisation technologies for around the past 8 years. I started, as quite a lot of people do, working with PCs after playing with such iconic systems like the ZX81, ZX Spectrum and then progressing through 386s, 486s, Pentiums etc. After being headhunted at sixth form to work for a small company based around Hertfordshire, UK. I began working with small businesses and gaining a lot of hardware experience. Three years later, after helping to increase the size of the business, I needed to gain exposure to a larger environment to progress my own career. I joined a large manufacturing company around Electronic Test and Measurement which progressed my skills onto more PC work, hardware work and then onto Server Operating Systems. I progressed again onto a consultancy company based in Reading, UK. Initially working as an engineer performing hardware / software installations for larger companies contracted out to the consultancy company, I moved up into a Consultant position continuing my travel across the UK assisting and providing solutions to companies. I finally moved on again to my current position, working back in Hertfordshire, UK. Again working for a large manufacturing company, this time with over 50,000 users worldwide. I am responsible for the datacenter hardware, the storage environment, the vmware environment and also implementing their new Citrix XenApp farm. My days are busy but also productive, its a friendly environment and in my four years of being with the company, I have seen many changes in technology and infrastructure in use within the company. About the site I started this site as I had been thinking of having more of a presence on the web for a while. On a daily basis, I perform tasks and use tools that others may not use or may not think to do and therefore I thought that I would share some of these experiences and tips with others to help with their day to day work. Currently, my main focus of work is around VMware and Veeam Backup & Replication but hopefully as my tasks progress, I’ll be able to share useful bits of information about other areas of IT as well.
