can only see 2 tb of 6 on raid 5 in windows 2003 sbs

I have a server setup with raid 5 and i can see 2 tb of the raid. However it see the other 3 tb of space and in disk manager it says the disk space is unallocated. When i right click on the unallocated space i do not have the option for creating a partiton. How do i use the 3 tb of unallocated space?

You will have to start from scratch since the drive needs to be partitioned by the RAID controller, not in software. You can convert to GPT with 32 bit Windows.

So basically windows 2003 sbs will only see 2 tb of my 5 tb raid 5.
Just downloaded partiton magic and it did not allow me to allocate space either.

Did you convert it to a GPT disk?

Hope this helps!

You cannot boot to a GPT disk, so you cannot convert the whole disk to GPT.
You cannot have a partition larger than 2TB, unless GPT.

So, basically, your options are to have partitions smaller than 2TB, or - if you need a partition larger than 2TB - you need to have a smaller disk for the OS, for example:

2x1TB (RAID 1) = OS (1TB)
4x1TB (RAID 5) = DATA (3TB)

In order to see all 3TB, you will need to convert the disk created by the RAID 5 to GPT.

I set it up as 6 tb hardware raid 5 and then installed os on 1tb.  do i need to repartition and reinstall?

It is not 64 bit so i cannot convert to gpt.

Rebuilt it using smaller partitions. Thanks
