I use to have a physical server with a few drives that were iSCSI. Server had problems so i cloned the physical server to a VM (VMWare ESXi 4.1), i did not clone the iSCSI drives to VMDK drives, i just reatached the iSCSI drives to the newly created VM.
I am now decomissioning the EMX AX4-5i SAN that is hosting the iSCSI drives(moving to a EMC VNXe), i need to recreate those drives on the VM server as VMDKs. I am allowed up to 3 hours of system downtime. What is contained on these drives are a total of around 2 TB of 1-5 KB files(spread over multiple iSCSI drives, i will not hit the 2TB VMware limit), imposible to do a full file copy this in the time frame i have. At the end of the system down time, i do not need all the data copied, but i do need to have at least folder/directory structure and all the permissions on those folders and directorys copied over.
tools, that i have, that may be of use: Beyond Compare, VMWare/VCenter/VMWare Conversion tool
looking for a game plan on how to get the the directory structure and permissions copied over to my new VMDK drives; with in the 3 hours, then plan on how to eventaly get the rest of the data put into the folders (i have as much time as it takes for this second part)
