Wrench Disk controller reassignment
Hi

The scenario in the oracle t4-1 hardware with solaris 10 is as follows:

1. The initial install on the server was performed with an incorrect disk layout.
2. New disks were ordered and slot into the server.
3. The disks are allocated a controller and a disk number based on the disk or replacement disk WWN.
4. This allocation is dependent on the disk not on the slot.
5. The install on the server requires the slots and the controller and the disk allocation to be different than the original install
6. The disk allocation is at a lower level than the operating system and despite several installs of the operating system and attempts to manual configure/unconfigure the disks this has not been possible

I need to reassign the controller numbers for my disks.

Currently, they are like this:

i.e. i want to swap around the position of disk 1 and disk 2.

Does anyone know how to do this?
