Unable to import Backup Exec Deduplication folder

Problem

Importing Backup Exec Deduplication folder fails with error "Unable to create deduplication disk storage"

Error Message

"Unable to create deduplication disk storage"

UMI: V-287-40960-39685

PDDE-Config.log shows the below errors:

1. First error when changing drive letter from R: to S:

Error: 25009: _LocalStore::loadFSTab: the first mount point R:\BackupExecDeduplicationStorageFolder\data doesn't match

the storage path S:\BackupExecDeduplicationStorageFolder\data in contentrouter.cg

Error: 25009: _LocalStore::init: failed to load fstab.cfg file.

2. Second error after changing the drive letter of fstab.cfg described later to S:

Error: 25009: _LocalStore::loadFSTab: CRC of fstab file mismatch, caculated value is 3426554476.

Error: 25009: _LocalStore::init: failed to load fstab.cfg file.

NOTE: PDDE-CONFIG.LOG is located at X:\BackupExecDeduplicationStorageFolder\log location.

Cause

This may occur if the Deduplication folder is moved to a different drive than the original and is being imported back (due to space constraints)

Solution

Fstab.cfg located in "X:\BackupExecDeduplicationStorageFolder\etc\puredisk\" will need to be edited and changed with the correct drive letter and the correct calculated CRC value as shown in the "PDDE-Config.log".

Following are the contents in the "fstab.cfg" which may need correction:

Count=1
Path=S%3A%5CBackupExecDeduplicationStorageFolder%5Cdata WTENABLE=Y
CRC=3426554476

Note:

• The 1st letter in the "Path" is the drive letter and has to match with the current drive where Deduplication folder has to be imported.
• CRC has to match with the value seen in the "PDDE-Config.log"
