1 Overview of Data Integrity Check Function Overview Data Integrity Check insures validity and protects Oracle data stored on the array. Data Integrity Check has the following two purposes (see Figure 1): • Preventing invalid data from being written to the array When data is stored on the disk array, the data is transferred through many paths and can become invalid. Data Integrity Check ensures that the Oracle data is valid before it is written to the disk array.
Figure 2 shows the Data Integrity Check components and their functions for Oracle data check. For requirements (such as product name or versions), refer to ”Data Integrity Check Operating Environments and Prerequisites” on page 11. Figure 2 Data Integrity Check components Data Integrity Check and RAID Manager Data Integrity Check is configured and operated using Data Integrity Check commands in RAID Manager XP. For RAID Manager operations, refer to the HP StorageWorks RAID Manager XP User’s Guide.
2 Data Integrity Check Operating Environments and Prerequisites Data Integrity Check requires the following: • A Command View XP array (see ”Requirements for the array” on page 11) • A Host server that supports an Oracle database and has RAID Manager installed (see ”Requirements for the Host Server” on page 11) • An Oracle-data validation service (see ”Restrictions and Conventions” on page 12 Requirements for the array Data Integrity Check requires a properly configured array and a channel adapter with th
• Sun® Solaris™ 8 or better. For further information on the Solaris™ platform, refer to the HP StorageWorks XP Remote Web Console user guide for XP12000/XP10000 • HP-UX 11.0 or better. For further information on the HP-UX platform, refer to the HP StorageWorks XP Remote Web Console user guide for XP12000/XP10000 • Windows 2000 Advanced Server (Service Pack 3 or later) • AIX 5L Version 5.1 ML3 Oracle database One of the following Oracle databases is required.
• If you want to change the configuration of the LDEVs (for example, decreasing the set LDEVs, creating CVs), you need to delete the setting of Data Integrity Check using RAID Manager first, and then perform the change. For host servers: • Do not write data other than Oracle data to the Oracle data check volume (LU). If multiple paths are set to the same volume (LU), check if those paths are not all set as the target of Oracle data check.
