I am trying to build a disaster recovery environment using the ESXI 4.1 free software and a 5TB Lacie NAS for my iSCSI recovery environment but keep running into issues with disk allocation. After configuring the RAID of my Lacie I am reduced to roughly 2.5TB of space, but ESXI will only recognize up to 2TB. I've been though the Lacie support site trying to find instructions for creating smaller iSCSI partitions like we have in my production envornment which uses a fully licensed version of ESXI 4.1, but the instructions from Lacie are rather cryptic and seem to be oriented to Windows Storage Server iSCSI and not ESXI. Has anyone successfully mounted a NAS device to an ESXI 4.x server and have any pointers to share to help guide me in the right direction for setting up my DR environment? Thanks!
From what you write, mounting the NAS system is not the issue. The issue you have is that ESXi 4.x only supports LUNs with up to 2TB minus 512 bytes. This changed with ESXi 5.0 which now supports LUNs with up to 64TB. So if you need to go with 4.x you will have to split the RAID on the storage and present multiple smaller LUNs to the ESXi host.
