Top 20 IBM Server & Hard Drive Faults We Recover From
Our engineers successfully recover data from a vast range of IBM-specific and enterprise storage faults. Here are twenty of the most common, with a detailed explanation of the fault and our professional recovery process.
- IBM ServerRAID Controller Failure
- Fault Details: The physical RAID controller (ServeRAID M5000 series, etc.) fails, taking the entire logical drive offline. The configuration metadata stored on the controller may be lost or corrupted.
- Recovery Process: We remove the hard drives from the server and create full sector-by-sector images of each member drive. Using the RAID metadata stored on the drives themselves, we virtually reconstruct the array in software, bypassing the failed hardware controller entirely.
- Multiple Drive Failure in RAID 5/6 Array
- Fault Details: The simultaneous or sequential failure of two or more drives in a redundant array exceeds the fault tolerance, causing volume collapse and data inaccessibility.
- Recovery Process: We image all drives, including the failed ones. Using advanced parity analysis and data stitching techniques, we create a composite image of the array from the best available data segments across all drives.
- Failed RAID Rebuild Process
- Fault Details: The automatic rebuild onto a replacement drive is interrupted or fails, often due to an undetected read error on another member drive, corrupting the array metadata.
- Recovery Process: We analyse the drives to determine the state of the array before the failed rebuild. We then reconstruct the data using this pre-failure state, effectively rolling back the damaging rebuild process.
- RAID Configuration Metadata Corruption
- Fault Details: The critical metadata that defines the RAID structure (drive order, stripe size, parity) on the controller or drives becomes corrupted, making the array unrecognisable.
- Recovery Process: We perform a manual analysis of all drives to identify RAID parameters by locating repeating data patterns, parity blocks, and file system signatures to rebuild the configuration from scratch.
- JBOD Member Drive Failure
- Fault Details: A single drive in a “Just a Bunch Of Disks” (JBOD) or Spanning configuration fails, rendering the entire spanned volume inaccessible.
- Recovery Process: We recover the data from the remaining functional drives and then perform physical recovery on the failed drive to retrieve its data segment, subsequently reconstructing the complete spanned volume.
- AIX JFS/JFS2 File System Corruption
- Fault Details: The Journaled File System or its enhanced version on IBM AIX systems suffers from superblock corruption, inode table damage, or journaling failures.
- Recovery Process: We use specialised tools to repair the corrupt journal and critical file system structures. Backup superblocks and Agile Self-Healing data are utilised to restore file system integrity.
- IBM i (AS/400) Storage Pool Damage
- Fault Details: The single-level store architecture on IBM i systems experiences damage to system or user storage pools, often due to hardware issues.
- Recovery Process: We work with the low-level object-based structure, repairing damaged pointers and system objects to restore access to libraries, files, and programs.
- SAS HDD Read/Write Head Assembly Failure
- Fault Details: The delicate read/write heads in enterprise SAS drives become damaged or contaminated, often producing a characteristic clicking sound.
- Recovery Process: This is a critical procedure performed in a controlled environment. We source an identical donor drive and perform a precise head stack exchange to enable imaging of the platters.
- Enterprise SSD Controller Failure
- Fault Details: The sophisticated controller on IBM server-grade SSDs fails, rendering the NAND flash memory inaccessible through standard interfaces.
- Recovery Process: We use chip-off recovery or specialist hardware to read the raw NAND flash memory directly. The complex data reconstruction involves reverse-engineering the Flash Translation Layer (FTL) to reassemble the user’s data.
- Backplane Communication Failure
- Fault Details: The server’s drive backplane fails, preventing communication with all or a group of drives, even though the drives themselves are healthy.
- Recovery Process: We remove the drives and connect them directly to our recovery hardware. The drives are then imaged individually, and the RAID array is virtually reconstructed.
- Firmware Corruption on Enterprise HDD/SSD
- Fault Details: The drive’s internal firmware becomes corrupted, often during a power loss or failed update. The drive may not spin up or may be detected with an incorrect capacity.
- Recovery Process: Using specialised tools, we access the drive’s service area and repair the corrupted firmware modules using known-good resources, restoring drive functionality for imaging.
- Bad Sector Propagation
- Fault Details: Media degradation causes a cascading effect of bad sectors, overwhelming the drive’s G-list and causing the drive to drop from the array.
- Recovery Process: We use imaging hardware with advanced error correction and controlled re-reads to create a stable clone. The redundant nature of RAID is then used to fill in any remaining unreadable sectors.
- Logical Volume Manager (LVM) Corruption
- Fault Details: The metadata governing the Linux or AIX Logical Volume Manager is damaged, making the logical volumes within a volume group inaccessible.
- Recovery Process: We repair the LVM metadata by locating backup copies or manually reconstructing the volume group, physical volume, and logical volume mappings.
- Partition Table Corruption on System x
- Fault Details: The Master Boot Record (MBR) or GUID Partition Table (GPT) on a server’s boot drive is damaged, preventing the operating system from loading.
- Recovery Process: Our engineers manually analyse the drive’s sectors to locate backup partition tables or reconstruct the partition map from file system signatures.
- Power Surge Damage to Server Components
- Fault Details: A voltage spike damages multiple server components, including drive PCBs, RAID controllers, and backplanes.
- Recovery Process: We diagnose and address damage on a per-component basis, which may involve PCB repairs and component replacements on multiple devices before data reconstruction can begin.
- Controller Cache Corruption
- Fault Details: Data in the write-back cache of the RAID controller is lost due to a power failure or controller malfunction, leading to file system inconsistency.
- Recovery Process: We perform a deep analysis of the file system, using journaling data (if available) to roll back transactions to the last consistent state, repairing the resulting inconsistencies.
- Hot-Swap Mismanagement
- Fault Details: The incorrect drive is removed from a live array, or a drive is inserted into the wrong bay during a replacement, causing configuration confusion.
- Recovery Process: We determine the correct drive order by analysing data synchronisation across the drives and then virtually reassemble the array with the proper configuration.
- S.M.A.R.T. Errors & Predictive Failure
- Fault Details: The drive’s internal monitoring system logs excessive reallocated or pending sectors, indicating imminent failure, but the drive fails before proactive replacement.
- Recovery Process: We immediately create sector-by-sector clones of all drives in the array, prioritising the failing one, to secure the data before attempting reconstruction.
- VBMS/TSM Backup Catalog Corruption
- Fault Details: The catalog/database for IBM Tivoli Storage Manager (TSM) or Veritas Backup Exec becomes corrupted, making backup sets unreadable.
- Recovery Process: We repair the catalog or, if necessary, extract data directly from the backup media (tapes, disk-based backups) by parsing the backup set format.
- Physical Platter Damage from Head Crash
- Fault Details: The read/write heads contact the platter surface, causing physical scratches and permanent data loss in specific areas.
- Recovery Process: Using specialised hardware, we image the drive multiple times to extract as much data as possible from the undamaged areas, bypassing the physically damaged sectors.
