Test Your DK for Linux Environment

The following test scenarios have been included to guide you as you get started evaluating SIOS Protection Suite for Linux. Before beginning these tests, make sure the data replication resources are in the mirroring state.

*Note: For these test examples, the Primary Server is referred to as LINUXPRIMARY. The Backup or Secondary Server is referred to as LINUXSECONDARY.

1. Manual Switchover of the Mirror to Secondary Server

Procedure:

• From the LifeKeeper GUI, right click on the top of the resource hierarchy on the Secondary Server (LINUXSECONDARY) and choose IN SERVICE.
• Click “In Service” in the window that pops up

Expected Result:

• All resources will be removed from service on the Active Server (LINUXPRIMARY).
• Beginning with the dependent resources, all resources will be brought in service on LINUXSECONDARY.
• During this process, the direction of the mirror reversed. Data is now transmitting from LINUXSECONDARY -> LINUXPRIMARY
• At this point, all resources are now active on LINUXSECONDARY.

Tests/Verification:

• Using the LifeKeeper GUI, verify the mirror is now reversed and mirroring in the opposite direction. Right click on the “datarep-mysql” resource and select Properties
  

• Run “df –h” to verify that the /var/lib/mysql replicated filesystem is mounted as an “md” device (example: /dev/md0”) on LINUXSECONDARY

2. Manual Switchover of the Mirror back to Primary Server

Procedure:

• From the LifeKeeper GUI, right click on the top level of the resource hierarchy on the Primary Server (LINUXPRIMARY) and choose IN SERVICE.
• Click “In Service” in the window that pops up

Expected Result:

• All resources will be removed from service on the Active Server (LINUXSECONDARY).
• Beginning with the dependent resources, all resources will be brought in service on LINUXPRIMARY
• During this process, the direction of the mirror reversed. Data is now transmitting from LINUXPRIMARY -> LINUXSECONDARY

Tests/Verification:

• Using the LifeKeeper GUI, verify the mirror is now reversed and mirroring in the opposite direction. Right click on the “datarep-mysql” resource and select Properties

• Run “df –h” to verify that the /var/lib/mysql replicated filesystem is mounted as an “md” device (example: /dev/md0”) on LINUXPRIMARY
