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:
but I would like them to be like this:
i.e. i want to swap around the position of disk 1 and disk 2.
I'm not at all sure that I understand what you are trying to do having re-read your post twenty times.
Why do you care what order the drives are?
Is this the scenario? You installed a server and then decided that the disk drives needed changing for some reason? You put a completely new set of drives in the server and restored the original installation from backup but it won't run???? Is that it?
Thanks for the reply.
Its a zfs server and the factory install was done using an incorrect disk configuration (two 600gb disks and two 300gb disks). By the time the server got to me, I needed to reinstall solaris with the correct number of disks, so i added three 300gbSSD disks (for a sybase db) and another 600gb disk for the hotspare pool.
However the solaris install puts the root disk on disk0 (300gb) but at the end of the solaris sys-unconfig, the svm defines disk1 (600gb) as the root mirror.
Ideally, i need my 300gb root disk mirrored to another 300gb disk.
I've moved around the disks physically and tried cfgadm, but no luck.
Do you have any ideas?
So are you restoring data from the original installation or is this a completely new build with the new disks?
NOTE TO MODERATORS: Can you please move this thread to mainstream Solaris forum. The OP is in hardware but it's actually a configuration issue. We need members with the right skills to see this.
You say that the platform is a T4-1 and this box usually has a built-in hardware raid controller. You seem to be saying that the 'factory' install mirrored the first two slots, which is normal for factory setup.
Does your box have a built-in hardware raid controller?
If so, could that be the reason the first two slots are mirrored??
If so, you can break that mirror with the raid tools and create another mirror of your choice.
I may be completely wrong on this but you need to check it out.

Hi,
I have a Sun Fire V440 server that fails to boot up correctly. A lot of services are not started and the sytems acts really slow to commands. During boot I can see the following Error:

I changed disk controller. Unplugged every disk, inserted another controller card, an IBM M1015. The disks are recognized in BIOS, and the controller card's BIOS shows up. But after that, I drop into GRUB and a prompt. That is all.

So today I tried to upgrade a customer from a Proliant with an HPSAS controller to an Intel server with a MEGASAS controller.
First, I downloaded the megasas driver from SCO and installed it on the old system.
Then I created a new Microlite Edge emergency boot cd with the new driver on it.

Hello all,
How does the Solaris identifies the controller subscript ? ( like c0txdxs0 or c1txdxsx ?? )
I have a unix box ( Ultra 30) running with 2.5.1.
When I connected an external hard disk to the on-board scsi port, it got identified as c0t1dxsx...
