Solution 1012029.1 : Converting a Sun Fire[TM] Server from a single segment/single domain configuration into a dual segment/dual domain configuration.

Applies to:

Sun Fire 3800 Server
Sun Fire 4800 Server
Sun Fire 6800 Server
Sun Fire E4900 Server - Version: Not Applicable and later [Release: N/A and later]
Sun Fire E6900 Server - Version: Not Applicable and later [Release: N/A and later]
All Platforms

Goal

Converting a Sun Fire[TM] 6800 or E6900 platform from a single segment/single domain configuration into a dual segment/dual domain configuration.

Current Configuration:

Single Segment
Domain A: SB0, SB1, SB2, SB3, SB4, SB5, IB6, IB7, IB8, IB9
Assuming boot device is located in either IB6 or IB8
Assuming resources in IB7 and IB9 are not required for Domain A

Desired Configuration:

Dual Segment
Domain A: SB0, SB2, SB4, IB6, IB8
Domain C: SB1, SB3, SB5, IB7, IB9

Solution

Items to keep in mind:

I/O should be split between remaining I/O boats for redundancy
Another boot device (D130/D240) should be available
Being able to utilize one side of each D240/D130 for mirroring of OS
Application on Domain A will not overload a smaller configuration

Procedure:

Schedule down time for "Domain A"
Verify changes been made to "Domain A" OS/Applications to not utilize IB7 and IB9
Connect to the system controller and enter the platform shell
Transition to Domain A by using the "console a" command
Log into the domain and bring down OS
After the OS was down, use the escape sequences to transition back to the domain shell level
Issue a "setkeyswitch off" command
Transition back to the platform shell by using the "disconnect" command
Configure platform for dual partition using the "setupplatform" command
Reassign the boards for Domain C utilizing the "deleteboard" and "addboard" commands. The following boards should be moved from Domain A: SB1 SB3 SB5 IB7 IB9
Transition to Domain A by using the "console a" command
Bring the OS back up by issuing a "setkeyswitch on" command
Verify that OS/Applications function with IB6 and IB8 resrouces only
Utilize the escape sequences to transition back to the domain shell and then "disconnect" to get back to the platform shell
Transition to Domain C by using the "console c" command
Provide setup infomation by issuing the "setupdomain" command
Attach appropriate devices to IB7 and IB9 (e.g. boot device & network cable)
When prepared, use the command "setkeyswitch on"
Install appropriate OS/Applications from the 'ok' prompt
