Some of that is outside of my control
This is the method that was decided upon... we have become pretty endeared to using recovered Virtual Machines or volumes from our Production side; overall it has reduced our RTO significantly due to the ease of importing synchronized data.
Part of the long standing issue we have had with maintaining the OS portion at the DR site is changes made in production that don't get replicated to the DR environment. Those changes are supposed to be done, but often still get missed. While there is always the 'so and so forgot to...' and then management whines about it; doing a full replication of even the boot environments simply factors out those human problems. For instance - a new mount point is added or an old mount point is removed.. a ton of little annoying things. Then when we test out DR processes, sometimes these 'little things' that we are unaware were changed, can cost us large amounts of time. Lately, we have been consolidating ZPOOLS on Solaris and every time we test - we run into issues with them.
But overall this works very well. Everything is 100% except for this /boot MPATH issue; and honestly - the systems will run on a single path just fine. But you know.. that's not good enough for a geek such as myself! lol
Thanks for your input too
