Work Notes 1:SMC Management node upgrade steps

A: Test environment:

Operating system:SLES SP1 x86_64

The SMC version is:1.4.0

Second: The operation steps are as follows

1. obtain a higher-level SMC management system with DD or clone

2. after opening the new management node, first delete the previous network Udev rules and remove all the hosts added in the SMC, and then restart the system

3. according to the actual environment to modify the hosts file, extranet IP and so on

4. Add the appropriate host (can be quickly imported through the hosts.conf file)

. Create a nodes.conf file

#touch nodes.conf

MAC Address host name IP address Startup type Unique identifier description

For example :

0050455c0392 n001192.168.4.1 Boot_mode 1 node_n001

0050455C03A2 n002192.168.4.2 Boot_mode 2 node_n002

. Select "Import Host" from the "file" menu

The Host List Import tool looks like this

. Select thehost list file type importing.

If you change thefile type, click Refresh to update the dialog.

. Enter Thepath for the file, want Toimport or click Browse to locate the file.

. Review thelist of the hosts to the import Andun-check any of the hosts you does not want.

Errors display foritems that cannot is imported.

. Click Importto Import the list of hosts.

. Click Close.

5. Open the SMC client and COPY to regenerate a new payload such as the name "compute-20141216-payload"

6. the "root" directory of this new payload is

/opt/sgi/sgimc/imaging/root/payloads/compute-20141216-payload

7. go to the "root" directory and make the following changes

Change the hosts file

Admin:/opt/sgi/sgimc/imaging/root/payloads/compute-20141216-payload/etc#cp/etc/hosts./

To delete an existing network Udev rule

ADMIN:/OPT/SGI/SGIMC/IMAGING/ROOT/PAYLOADS/COMPUTE-20141216-PAYLOAD/ETC/UDEV/RULES.D#RM-RF 70- Persistent-net.rules

Delete existing ssh_known_hosts files in the etc/ssh directory

ADMIN:/OPT/SGI/SGIMC/IMAGING/ROOT/PAYLOADS/COMPUTE-20141216-PAYLOAD/ETC/SSH#RM-RF ssh_known_hosts

Change NIC configuration information according to actual situation

The current NIC configuration information is as follows

Admin:/opt/sgi/sgimc/imaging/root/payloads/compute-20141216-payload/etc/sysconfig/network#ls

config if-down.d ifcfg-eth0 ifcfg-ib0 Ifcfg-lo Ifroute-lo Routes

DHCP IF-UP.D ifcfg-eth1 IFCFG-IB1 ifcfg.template Providers Scripts

If at present we only need a management network Port (eth0), then do not need to delete the network port configuration information, the configuration is completed as follows

Admin:/opt/sgi/sgimc/imaging/root/payloads/compute-20141216-payload/etc/sysconfig/network#ls

Config IF-DOWN.D ifcfg-eth0 ifcfg.template providers

DHCP if-up.d ifcfg-lo ifroute-lo scripts

8. in the SMC Management window, put the payload in the VCS Management

Double-click the payload, and in the Open window, click "Check in" on the bottom left corner.

9. within the SMC Management window, a new image named "compute-20141216-image" is generated by COPY mode

Edit the image, replace the payload with the payload we made earlier , adjust the corresponding system partition and mount information, and then click "Apply"-"Check in "

Brush (deploy) Compute nodes

One . after the compute node is deployed, set the no password access step on the Admin Management node

admin:~ #ssh-keygen// Enter key

admin:~ # CD. ssh/

ADMIN:~/.SSH # CP Id_rsa.pub Authorized_keys

Admin:~/.ssh #chmod Authorized_keys

First Use ssh to access yourself in order to add the admin to the known_hosts file

admin:~ # SSH Admin

Note: If this error message occurs when you perform the above steps, the agent admittedfailure to signusing the key, and you are prompted to enter the password, you need to execute the following command

admin:~# Ssh-add

Copy the /root/.ssh directory to the /root/ directory of all COMPUTE nodes

admin:~ # scp-r/root/.ssh/ compute node host name :/root/

Note: The first time is password-based authentication, so enter the password

Finally, copy the /root/.ssh/known_hosts file to the /root/.ssh/ directory of all COMPUTE nodes .

admin:~ # scp/root/.ssh/known_hosts compute Node host name :/root/.ssh/

Other relevant configurations as required
