Installation and Configuration
21EBS with HP OpenView Storage Data Protector v5.1 Implementation Guide
Installation Best Practices
■ Follow the HP StorageWorks EBS Compatibility Matrix and the HP
StorageWorks Enterprise Backup Solution Design Guide.
— The matrix of hardware, software, and firmware is updated monthly and
helps customers and support personnel maintain their EBS environment.
It is not necessary to immediately update an environment to the latest
revision on the matrix. However, you should be aware of updates and
changes if you experience any problems that may be related to newer or
older software, driver, and/or firmware versions.
— The design guide describes currently supported EBS hardware
configurations and how to efficiently and effectively provide shared tape
library backup in a heterogeneous SAN environment.
■ Limit the size of Data Protector cells.
— The recommended maximum size for a Data Protector cell is 100 client
systems.
Note: Multiple cells may be centrally managed using Manager-of-Managers.
■ Do not create cells with multiple time zones. Each cell should be within one
time zone.
■ Limit rebooting during backup windows.
— Rebooting hosts in an EBS environment during backup windows can
cause job failures and configuration errors.
— When rebooting is necessary, verify the configuration of the host when
maintenance or reboot is complete.
■ Use the DNS Connection Check tool to verify if:
— The Cell Manager properly resolves every other client of the cell
— Every client of the cell properly resolves the Cell Manager
— Every system, on which the Media Agent was installed, resolves every
other client
— Each system resolves every other system accommodating a Media Agent
■ Be sure the latest Data Protector and OS patches have been installed.
