We have purchased a new SAN on lease (clariion cx310), the old one (clariion cx300) has to go away in 30 days. Question is when I have the new array up and presented to the ESX hosts/farm, I carve up new luns and format them as VMFS luns I assume I need to migrate or move the virtual machines to the new luns? Can I do this via the GUI in virtual center or do I have to run some vmfsktools command to make this happen? This is an area I have never been involved in before. I will be able to shut these VMs down if needed. P.S. One virutal server has its datat drive as a RAW device mapping, will that be an issue. Anyone been in my shoes before? Any suggestions or can someone point me to a tech doc to assist me with this. many thanks in advance for your help.
