in <br>&gt; the target environment for this to work? for example, should disk
devices <br>&gt; naming on AIX be the same as in the source environment? when importing
the <br>&gt; mmsdrfs file, how is Scale going to know which disks should it assign
to <br>&gt; the cluster? by their hdisk name alone?<br>&gt; <br>&gt; Thanks again,<br>&gt; <br>&gt; <br>&gt; <br>&gt; 2018-01-24 2:30 GMT-05:00 Alex Levin &lt;<a href="mailto:alevin@gmail.com" target="_blank">alevin@gmail.com</a>&gt;:<br>&gt; Hi, <br>&gt; <br>&gt; We are using a  similar type of replication.<br>&gt; I assume the site B is the cold site prepared for DR<br>&gt; <br>&gt; The storage layer is EMC VMAX and the LUNs are replicated with SRDF.<br>&gt; All LUNs ( NSDs ) of the gpfs filesystem are in the same VMAX replication
<br>&gt; group to ensure consistency.<br>&gt; <br>&gt; The cluster name, IP addresses ,  hostnames of the cluster nodes
are <br>&gt; different on another site - it can be a pre-configured cluster without
<br>&gt; gpfs filesystems or with another filesystem.<br>&gt; Same names and addresses shouldn&#39;t be a problem.<br>&gt; <br>&gt; Additionally to the replicated LUNs/NSDs you need to deliver copy
<br>&gt; of /var/mmfs/gen/mmsdrfs  file from A to B site.<br>&gt; There is no need to replicate it in real-time, only after the change
of <br>&gt; the cluster configuration.<br>&gt; <br>&gt; To activate  site B - present replicated LUNs to the nodes in
the DR <br>&gt; cluster and run  mmimportfs as &quot;mmimportfs  fs_name

<br>&gt; wrote:<br>&gt; Thanks for answering.<br>&gt; <br>&gt; Essentially, the idea being explored is to replicate LUNs between
<br>&gt; identical storage hardware (HP 3PAR volumesrein) on both sites. There
is <br>&gt; an IP connection between storage boxes but not between servers on
both <br>&gt; sites, there is a dark fiber connecting both sites. Here they dont
