Workaround Recover the Hierarchical Storage Management Database (HSMDB) of the FSE partition PartitionName by performing the following steps:

1.Unmount the belonging HSM file system.

2.Delete the HSMDB directory from the local system. Linux specific

Path of the HSMDB directory is /var/opt/fse/part/PartitionName/hsm. Windows specific

Path of the HSMDB directory is %InstallPath%\var\part\PartitionName\hsm.

The value of %InstallPath% depends on the choice made in the FSE installation process. It defaults to C:\Program Files\Hewlett-Packard\FSE.

3.Mount the HSM file system.

4.Manually put all dirty files on the HSM file system on the migration candidate list.

5.Manually release files on the release candidate list or perform any other change on the HSM file system, but do not change the files on the migration candidate list.

The release candidate files will be automatically added to the release candidate list after migration.
