I’ve had to do a few quick SAN migrations recently that involved setting up new SAN array’s and performing the necessary steps to evacuate data from one device to another. These migrations generally involve –
- Documentation of current LUN layout on legacy SAN
- Documentation of current datastore layout within vSphere
- Creating new LUN’s on the destination device
- Creating new Datastores within vSphere to for the existing VMDK’s
The following script will automate the above steps. This script assumes that you are using these specific vendors, as well as a functional vCenter environment
Find the script here on my github
