From ILOM, the following command will send a break signal to OS:

Code: Select all

-> set /HOST send_break_action=break
Set 'send_break_action' to 'break'
Then, start the console connection.

Code: Select all

-> start /HOST/console        
Are you sure you want to start /HOST/console (y/n)? y

Serial console started.  To stop, type #.

{0} ok
Then, commands can be issued at ok prompt.

Find the RAID controller and select it to check how many disks are available:

Code: Select all

{0} ok show-devs
...
/pci@3c0/pci@1/pci@0/pci@2/scsi@0
...

{0} ok select /pci@300/pci@1/pci@0/pci@2/scsi@0

{0} ok show-children

T5-2 RAID configuration - II

Got the following feedback from Oracle support:
Oracle wrote:
T5-2 has 2 x LSI SAS2308 raid controllers

/pci@300/pci@1/pci@0/pci@2/scsi@0/iport@[1-4]/disk@[0-3] (Controller 0; LSI SAS2308 #1)
/pci@3c0/pci@1/pci@0/pci@2/scsi@0/iport@[1&2]/disk@[4&5] (Controller 1; LSI SAS2308 #2)

You should be able to see the other 2 disks on the 2nd controller from OBP using this path:

{0} ok select /pci@3c0/pci@1/pci@0/pci@2/scsi@0
{0} ok show-children
The other way to select controller is to use "devalias" to show (scsi0 and scsi1 are both RAID controllers):

It shows the other 4 devices.
Maybe I should select both controllers at the same time....

It didn't work the way I thought:

Code: Select all

Update the ticket again asking how I can see all 6 disks at the same time.

In fact, it doesn't really matter which 2 disks I pick for root disk mirror.
Maybe I will just pick 5000cca0163ee364 and 5000cca0164357b4 from select /pci@3c0/pci@1/pci@0/pci@2/scsi@0 and make it a mirror disk.

Here is what I did:

feedback from Oracle:
Oracle wrote: That is a limitation of the internal raid controllers.

When configuring a volume, or adding a hot spare disk, all the disks must be on the same controller. A volume cannot be built with member disks from both controllers.
Up to two logical volumes can be configured on each onboard RAID controller

Note: You will need to re-install Solaris after building the raid, as this operation wipes any data on existing disks.
