Migrating Symantec Veritas Cluster Server to HP Serviceguard for Linux

Technical white paper | Migrating Symantec Veritas Cluster Server to HP Serviceguard for Linux
Collect the resources information used by your VCS service group
The resource information of the VCS service group for your application can be used later while creating an SG/LX package
for the same application in the SG/LX cluster. The service group resource information typically includes storage (filesystems,
volume managers), network (IP subnets), and other OS resources used by the application.
• Collect the following details related to the IP being used by the application:
– IP device
– IP address
– Netmask
– NIC device
• Collect the following detail related to the volume group being used by the application:
– Volume group
• Collect the following details related to the logical volume group being used by the application:
– Logical volume and corresponding volume group
• Collect the following details related to filesystem being used by the application:
– MountPoint
– FSType
– FsckOpt
– BlockDevice
In addition to the resource information, there can be VCS application agent-specific information in the VCS service group that
can also be useful when configuring SG/LX package using an SG/LX toolkit. This typically includes the following:
• Collect the following details related to the application:
– Application configuration file path
– Application home or binaries dir
– Application startup and shutdown behavior flags
In this illustration, the following table has the VCS Apache service group resource information and the VCS Apache agent
specific information that can be required while creating an SG/LX package for the Apache Web Server.

Back up the application and configuration data
You should always back up the application data when you are going to make significant changes to a system configuration.
It is recommended to create a backup disk with all the application data.
