⁠6.3. Upgrading from Red Hat Storage 2.0 to Red Hat Storage 2.1 Using Red Hat Satellite Server

Unmount all the clients using the following command:
```
umount mount-name
```
Stop the volumes using the following command:
```
# gluster volume stop volname
```
Unmount the data partition(s) on the servers using the following command:
```
umount mount-point
```
Ensure that the Red Hat Storage 2.0 server is updated to Red Hat Enterprise Linux 6.2.z and Red Hat Storage 2.0 Update 6, by running the following command:
```
# yum update
```
You must register the system to the Red Hat Storage 2.0 channels in Red Hat Network.
Change into the /usr/share/rhn/ directory and get the SSL certificate using the following command:
```
# wget
https://Red Hat Satellite server URL/pub/RHN-ORG-TRUSTED-SSL-CERT
```

Edit the /etc/sysconfig/rhn/up2date file with the following information:

serverURL=https://Red Hat Satellite server URL/XMLRPC
noSSLServerURL=http://Red Hat Satellite server URL/XMLRPC
sslCACert=/usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT

Create an Activation Key at the Red Hat Satellite Server, and associate it with the following channels. For more information, refer to Section 4.3, “Installing from Red Hat Satellite Server”
```
Base Channel: RHEL EUS Server (v.6.4.z for 64-bit x86_64)

Child channels:
RHEL EUS Server Scalable File System (v.6.4.z for x86_64)
Red Hat Storage Server 2.1 (RHEL 6.4.z for x86_64)
```
On the updated Red Hat Storage 2.0 Update 6 server, run the following command:
```
# rhnreg_ks --username username --password passowrd --force --activationkey Activation Key ID
```
This uses the prepared Activation Key and registers the system to Red Hat Storage 2.1 channels on the Red Hat Satellite Server.

Verify if the channel subscriptions have changed to the following:

# rhn-channel -l
rhel-x86_64-server-6-rhs-2.1
rhel-x86_64-server-6.4.z
rhel-x86_64-server-sfs-6.4.z

Run the following command to upgrade to Red Hat Enterprise Linux 6.4 and Red Hat Storage 2.1.
```
# yum update
```
Reboot, and run volume and data integrity checks.
