8.3.6 Removing a dual or a bonded Gigabit Ethernet interconnect

In an HP SFS system where a dual or a bonded Gigabit Ethernet interconnect is used, you can downgrade

the system to use a single Gigabit Ethernet interconnect. The entire HP SFS system must be downgraded, as

described here (that is, you cannot downgrade some servers to use a single Gigabit Ethernet interconnect

and leave other servers using a dual or a bonded Gigabit Ethernet interconnect).

To downgrade a dual or a bonded Gigabit Ethernet interconnect in an existing HP SFS system to become

a single Gigabit Ethernet interconnect, perform the following steps:

1.

Unmount the file systems on all client nodes.

2.

Stop all file systems, as shown in the following example, where the

data

file system is stopped:

sfs> stop filesystem data

Repeat this command for each file system.

3.

Use the

configure system

command to unconfigure the old network, as follows:

a.

Enter the

configure system

command.

b.

Select the

Configure networks

option, and unconfigure the old network.

c.

If you are removing a bonded Gigabit Ethernet, select the

Delete a Bonded Network

device

option, and delete the bonded network device.

4.

Reconfigure all servers in the system by entering the

configure server

command, as shown in

the following example:

sfs> configure servers south[1-8]

5.

Shut down all of the servers in the system, as shown in the following example:

sfs> shutdown server south[1-8]

6.

Remove the dual-port Gigabit Ethernet NC7170 network adapter from the first PCI slot of each server.

Refer to the documentation for the adapter and the server for details on how to remove PCI cards

safely on your particular server type.

7.

Boot all of the servers.

8.

If Gigabit Ethernet (single, dual, or bonded) is no longer being used as an interconnect, ensure that

Gigabit Ethernet (

tcp

) is not listed as an interconnect for any file system. Enter the

show

filesystem

command and determine if

tcp

is listed as an interconnect for a file system; if it is,

enter the

modify filesystem filesystem_name

command, select the

Change

interconnect

option, and remove

tcp

from the list of interconnects for the file system.

Repeat this step for each file system where

tcp

was listed as an interconnect.

9.

Start all file systems.

10.

When the file systems restart, the client nodes can remount the file systems. If a client node fails to

remount a file system, reboot the client node.
