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.
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...

Hi,
I am a newbie to Solaris. I want to know how to find out the controller target and disk number on a SunFire V890 box that has 6X72GB disks. The probe-scsi output is as shown below:

Dear Solarizer,
If i have a disk let say like this c1t0d0s0
How to change the controller to be come example : c3t0d0s0

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.

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.

scsi_vhci - SCSI virtual host controller interconnect driver
DESCRIPTION
The scsi_vhci driver is a SCSA compliant pseudo nexus driver that supports Solaris operating system I/O multipathing services for SCSI-3
devices. This driver introduces a fundamental restructuring of the Solaris device tree to enable a multipath device to be represented as
single device instance rather than as an instance per physical path as in earlier Solaris versions.
The multipath SCSI target devices managed by this driver are identified and represented by using SCSI-3 VPD page(0x83) as the device's
unit address.
Symbolic links in /dev/[r]dsk continue to adhere to the cNtNdNsN format. cN is the logical controller number assigned to this driver
instance. tN is the global unique identifier (GUID) of the multipath target device (64/128 bits), represented as hexadecimal numbers.
The following is an example of a system with a A5000 storage array:
...
/dev/rdsk/c4t200000203709C3F5d0s0 -> ../../devices/scsi_vhci/
ssd@g200000203709c3f5:a,raw

The following is an example of a system with a T300 storage array:
...
/dev/rdsk/c1t60020F200000033939C2C2B60008D4AEd0s0 -> ../../devices/
scsi_vhci/ssd@g60020f200000033939a2c2b60008d4ae:a,raw

scsi_vhci/ssd@g60020f200000033939a2c2b60008d4ae:h,raw
The scsi_vhci driver receives naming and transport services from one or more physical HBA (host bus adapter) devices. To support multi-
pathing, a physical HBA driver must comply with the multipathing services provided by this driver.
The scsi_vhci driver supports the standard functions provided by the SCSA interface.
Configuration
The scsi_vhci driver can be configured by defining properties in the scsi_vhci.conf file.
The scsi_vhci driver supports the following property:
device-type-scsi-options-list
To add a third-party (non-Sun) symmetric storage device to run under scsi_vhci (and thereby take advantage of Solaris I/O multipathing),
you add the vendor ID and product ID for the device, as those strings are returned by the SCSI Inquiry command. As shipped, the
scsi_vhci.conf file contains, in part:
# device-type-scsi-options-list =
# "SUN SENA", "symmetric-option";
# symmetric-option=0x1000000;
For example,to add a device from a vendor with the ID of "Acme" and a product ID of "MSU", you would add:
device-type-scsi-options-list =
"Acme MSU", "symmetric-option";
symmetric-option=0x1000000;
In addition to "Acme," you also might want to add another entry, for example, a device from "XYZ" vendor with a product ID of "ABC:"
device-type-scsi-options-list =
"Acme MSU", "symmetric-option",
"XYZ ABC", "symmetric-option";
symmetric-option=0x1000000;

NOTES
In previous releases, the scsi_vhci.conf file supported the mpxio-disable property, which allowed you to disable Solaris I/O multipathing
on a system-wide basis. This property is not present in the current release of the Solaris operating system. Multipathing is always
enabled in scsi_vhci. If you want to disable multipathing, use the mechanisms provided by the HBA drivers. See fp(7D).
In previous releases, Solaris I/O multipathing was also known as MPxIO and Sun StorEdge Traffic Manager (STMS).
