Craig, VM Recovery Manager DR handles disaster recovery for Linux VMs using restart technology on top of the storage replication.
Here rootvg is given through SAN. And all the volumes including rootvg volumes will be mirrored to remote storage using storage replication.
In the event of DR, product creates VM at the target site using replicated storage volumes.
It also has DR capabilities to handle SAP HANA single instance, multi-instance recovery.
Product can also handle switching SAP HANA active and passive instances with in a site in case of failures and then perform disaster recovery across sites.
Here VM Recovery Manager dynamically creates VMs at target site during recovery. Since it uses restart technology all NPIV WWPNs and MAC also remains the same at target site.
One of the other interesting feature is that provides DR drill/failover rehearsal feature, without disturbing production VMs/workloads and also ongoing replication between production and DR.
Since this product works across all guest VMS like Linux, AIX and IBM i, dependencies can also be created among Linux and AIX workloads.
It has GUI and provides single click DR simplified options for 100s of VMs and workloads.
Let me know, if you need more details. We can go through details in the call.
Thanks.

Subject: Disaster Recovery options for Linux on Power?
As the title says, what are some options for disaster recovery of Linux running on Power architecture? Way back in the good old days when we ran AIX, I would simply cut periodic mksysb files that would be used for disaster recovery of the rootvg at our DR site. Is there something similar for Linux (specifically SLES 12 if it matters)? Maybe a different methodology entirely? We have a solution that works well for restoring the non-OS data once we get an environment laid down, it's just getting that initial environment that is causing up issues.
