Promise VTRAK m500i LUN

I am trying to create multiple LUNS on a Promise Vtrak M500i SAN. In the past on different SANS I have created my array, say 15 500Mb drives in a RAID 5 with Hot Spare, I have a 6.5 TB array (give or take). Then I would carve out LUNS specifying the LUN size.

I have not been able to create a LUN with a size other than using the whole array. I want to be able to carve out 500gb, 1tb or 1.5tb and so on.

Any idea if this is possible and how it is done. I have update the firm to the latest.

Any help would be great.

The data sheet is quite clear in that it supports up to 256 logical arrays, including lun carving, any combination of RAID levels at a time.   Are you using the GUI to do it?  From the screenshot, it looks pretty obvious.

Thanks for answering. I am using the GUI. from the screen shots it looks like I would have to create separate raids and then I could assign each array its own LUN. Am I missing something?

I have in the past created one large array then carved the LUNs from it.

Thanks for any input.
You can do either. the specs say you can carve an array into max of 32 pieces, total 256 logical devices, so that would mean 8 luns x 32 slices, or more luns with fewer slices
