This post was driven by a requirement to map RDM volumes on target side in preparation for a disaster recovery test.  I thought I would share some of my automation and process with regards to mapping RDM devices that will be used to present RecoverPoint replicated devices to VMs as part of a DR test.

Step 1:  Install VMware vCLI and PowerCLI

Step 2:  Open PowerCLI command prompt

Step 3:  Execute addvcli.ps1 (. .\addvcli.ps1)

PowerShell

Step 6:  Get SP collect from EMC CLARiiON / VNX array

At this point you should have all the data required to map the RDM volumes on the DR side.  I simply import the two CSVs generated by the scripts into excel (scsiluns.csv, mpath.csv) as well as the LUNs tab from the SP Collect (cap report).

Using Excel and some simple vlookups with the data gathered above you can create a table that looks like the following:

I could probably combine these three scripts into one but under a time crunch so just needed the data, maybe I will work on that at a later date or maybe someone can do it and share with me.
