As others have already said, you can't. However, ... 

RAID1 on the same LUN wouldn't work or make sense. However, to mitigate 
switch/path failures you could do the following to gain path-resiliency:

1. Create two LUNs identical sized on the SAN

2. On the SAN unit, present the LUNs out separate 
   fiber-adapters/paths/fabrics/switches.

3. Obviously you'll need to connect your HBAs to the two independent 
   paths. 

3. Use LVM or RAIDFrame to mirror the two LUNs into a RAID1 configuration.

4. Celebrate. You've used 2x the storage, but gained resiliency and can 
   withstand a complete path failure.

Thanks,
