Data Recovery from Sun Solaris (SunOS) systems

Definition: Solaris is a UNIX based operating environment developed by Sun Microsystems. Originally developed to run on Sun's own SPARC architecture workstations, Solaris now runs on many workstations from other vendors, including Intel.

Data Loss on Sun Systems: Human error apart, loss of data is usually due to either a corruption of the filesystem or hard disk drive failure:

Data loss due to Corrupt Solaris UFS, VxFS and HTFS filesystems: We are able to recover data from the following instances of filesystem corruption:

Super Block damage
Inode corruption
Damaged Partition information (including deleted, corrupt, repartitioned and missing partitions)
Volume Table of Contents (VTOC) and OLT table
Block Group Descriptor damage
Unix Data recovery software provides recovery after errors in Cylinder group
Damage caused to data structures by FSCK

Data Loss due to hard disk drive failure: The hard disks used in Sun systems are traditionally high performance (10,000 RPM) internal drives that use either SCSI or FibreChannel interfaces, they sometimes contain customized features specific to the Sun architecture they run on. Common failures include

What should I do?: Call the Data Clinic and talk your problem through with us on 0870 140 2525, or fill out our auto-form and we'll call you back

What should I not do?: We recommend avoiding filesystem repair utilities such as FSCK as they can often cause recoverable data to become unrecoverable.

Please note that all modern hard disk drives are manufactured to very high standards, fail infrequently and have very similar rates of reliability.

Solaris is Sun Microsystems' own version of the UNIX operating system that often runs on their own SPARC architecture.
