iscsi device on solaris 10 (x64)

Hello!

I have several disks discovered using iscsi protocol.
There disks are represented in OS like c2txd0 .

logs:

Is it possible to change drive path, for example, from c2t6d0 to c2t7d0?

It's important for me because I have to install oracle RAC on RAW devices.
