Steps:
1) Remove the GW service, if any, and remove it as a Resource
2) Remove the Service tied to the PowerFlex Gateway
3) Backup the gatewayUser.properties file:
cp /opt/emc/scaleio/gateway/webapps/ROOT/WEB-INF/classes/gatewayUser.properties /tmp/
4) Uninstall the GW RPM:
rpm -e $(rpm -qa | grep "EMC-ScaleIO-gateway")
5) Rename the host as desired:
#set new hostname
hostnamectl set-hostname your-new-hostname
#reboot host
shutdown -r
6) Reinstall the PowerFlex GW RPM:
GATEWAY_ADMIN_PASSWORD='<gw_admin_password>' rpm -ivh
7) Replace the gatewayUser.properties file with the one backed up:
cp /tmp/gatewayUser.properties /opt/emc/scaleio/gateway/webapps/ROOT/WEB-INF/classes/gatewayUser.properties
8) Restart the GW service:
systemctl restart scaleio-gateway.service9) Create a lockbox and store the MDM credentials:
10) Log in to the PowerFlex Gateway UI and navigate to the 'Maintain' tab. Approve the MDM/LIA certificates, then switch MDM ownership and repeat this for all Secondary MDMs
11) Add the GW back as a resource
12) Add the Existing Service back
13) Validate that the UI displays the updated GW name
Additional Information
If Secure Remote Services is configured, it must be reconfigured after the GW is re-installed.
This process is necessary due to the certificates created during install.
