Site Recovery Manager and ActiveCluster Part III: Creating Protection Groups and Recovery Plans

Now that all of the prerequisites are complete, it is time to start creating protection groups and recovery plans.

This is part 3 of this series, the earlier parts were:

Site Recovery Manager and ActiveCluster Part II: Configuring SRM

In my last post, I walked through configuring ActiveCluster and your VMware environment to prepare for use in Site Recovery Manager.

Site Recovery Manager and ActiveCluster Part I: Pre-SRM Configuration

In this post, I will walk through configuring Site Recovery Manager itself.  There are a few pre-requisites at this point:

  • Everything that was done in part 1.
  • Site Recovery Manager installed and paired
  • Inventory mappings in SRM are complete (network, folders, clusters, resource pools etc).
  • Downloaded and installed the FlashArray SRA 3.x or later on both SRM servers.

Site Recovery Manager and ActiveCluster Part I: Pre-SRM Configuration

About four years ago, we (Pure Storage) released support for our asynchronous replication and Site Recovery Manager by releasing our storage replication adapter. In late 2017, we released our support for active-active synchronous replication called ActiveCluster.

Until SRM 6.1, SRM only supported active-passive replication, so a test failover or a failover would take a copy of the source VMFS (or RDM) on the target array and present it, rescan the ESXi environment, resignature the datastore(s) then register and power-on the VMs in accordance to the SRM recovery plan.

The downside to this of course is that the failover is disruptive–even if there was not actually a disaster that was the impetus for the failover. But this is the nature of active-passive replication.

In SRM 6.1, SRM introduced support for active-active replication. And because this type of replication is fundamentally different–SRM also changed how it behaved to take advantage of what active-active replication offers.

Tech Preview: vCenter Site Recovery Manager with ActiveCluster

An increasingly common use case for Active-Active replication in vSphere environments is vSphere Metro Storage Cluster (vMSC) which I wrote about in this paper recently:

https://support.purestorage.com/Solutions/VMware_Platform_Guide/002ActiveCluster_with_VMware/PDF_Guide%3A_Implementing_vSphere_Metro_Storage_Cluster_With_ActiveCluster

This overviews how a stretched vSphere cluster interacts with the active-active replication we offer on the FlashArray called ActiveCluster. Continue reading Tech Preview: vCenter Site Recovery Manager with ActiveCluster

Multi-site FlashArray Configuration with Site Recovery Manager

The FlashArray Storage Replication Adapter for VMware Site Recovery Manager supports many:many replication since the 2.0 release of the SRA. Use of test failover, failover and reprotect is no different than with 1:1, and nor is the setup of the volumes. The only real difference is how you configure the array managers in SRM. So let’s review how this is done.

FlashArray Storage Replication Adapter version 1.5 for SRM

Hey all. Just wanted to let you know there is an updated Pure Storage FlashArray Storage Replication Adapter now posted on VMware’s Site Recovery Manager compatibility guide:

SRM Cannot Identify Replicated Datastores on iSCSI Devices

So we ran into a customer issue recently with VMware Site Recovery Manager that I have not seen before and have not found any on-point articles on, so I thought I’d share this one. Was an insidious one too, when troubleshooting this one I could not find the issue, eventually one of our rockstar escalation engineers at Pure (Jacob Hopkinson) figured it out after going through SRM debug logs line by line. Comes down to case sensitivity in iSCSI IQNs. I’ll explain…

Site Recovery Manager and Raw Device Mappings (RDMs)

Somewhat surprisingly I have been getting a fair amount of questions in the past few months concerning VMware vCenter Site Recovery Manager and Raw Device Mappings (RDMs) and using this with Pure Storage. Common question is whether or not we support this (we do) but more commonly it is about how it works. There is a bit of a misunderstanding on how they differ or do not differ from VMFS management in SRM. So figured I would put a post out to explain this. Old topic somewhat, but worth reviewing for those newer SRM customers. Plus, I haven’t found a whole lot of on-point posts anywhere, so why not?

VMware SRM and the PBM & PreCloneCheckCallback error

Quick post here. I recently updated my environment to vCenter 6.0 Update 1 and VMware Site Recovery Manager 6.1 and after my first attempted test failover (and subsequent ones) the test would always fail when it tried to power on the virtual machines. Some powered-on and some didn’t. The following errors appeared for about half of my VMs:

Querying SRM for Protected VMs with PowerCLI

I was recently asked how to query SRM for protected VMs and I decided it would make a good quick blog post. There is a great post here on using PowerCLI with SRM, but it doesn’t show the information to return per virtual machine information by default. Needs a bit more.

All it returns is a SRM-based virtual machine ID which doesn’t relate to what a user is probably looking for (a virtual machine name). So it needs a few more simple steps. The following script which can be found on my GitHub page here that does the following things:

  1. Connects to a vCenter
  2. Connects to SRM
  3. Creates a log folder with a time stamp in the name
  4. Iterates through each Protection Group
  5. Logs every virtual machine in that protection group
