If you go to Configuration \ Storage Adapters and select the Areca controller do you see the LUN? I'm not sure if you can do it with the Areca, but with some controllers you can create multiple arrays on the same disks so you would be use all the space on the drivers but still have arrays smaller than 2 TB - 512 B.
Thanks for your help. In Configuration / Storage Adapters, the Areca Controller does not reveal enything:
Model: ARC-1110 4-Port PCI-X to DATA RAID Controller
Targets: 0 Devices: 0 Paths: 0
I did a rescan several times, but this did not help.
Note: Maybe the readme of the driver might be handy: ftp://ftp.areca.com.tw/RaidCards/AP_Drivers/VMware/ESX_4/Beta/Build90714/ (which is the latest online build)
I'll try ESX4 later on, see if that works
An upgrade of the Firmware (from v1.44 to v1.46) did the trick
How did you upgrade the firmware I have the ARC-1220 and the only way I see to upgrade the firmware is to have the whole suite loaded that has the web interface. Did you have to install it into a windows PC or something?
I was lucky to have the original hard disk (with Windows Server 2008). So, yew, I've used the web interface to upgrade the firmware. Perhaps you can use the DosFlash utility from the Areca-site. I have no experience with that however.
