Verifying the data integrity of migrated data

This topic describes how to verify migrated data.

Prerequisites

The integrity of the migrated data and metadata (such as permissions and creation time) is checked automatically during the data-migration process.

You can also manually verify data integrity after the data migration is complete using either the data-migration utility or your own verification tools. The data-migration utility traverses both the source and target file systems and compares the metadata, file size, and checksum. Discrepancies in the attributes are reported and, if possible, repaired. Differences in file size or checksum are considered a failed migration. If a file appears in one file system but not in the other, the migration is also considered failed.

Review the data-migration prerequisites before you begin migrating data.

Steps

  1. On the client machine, change to the directory where the migratedata command is located. For AIX®, Linux™, and Solaris, this is the /usr/tank/migration/bin directory. For Windows®, this is the c:\Program Files\IBM\Storage Tank\Migration directory.
  2. Invoke the migratedata –phase verify command.
