An unbootable hard drive volume is one of the common problems encountered by users working on the HP-Unix operating system. Some of the main reasons responsible for unmountable behavior are file system damage, metadata structure corruption, virus attack and more. One of the main consequences of an unbootable hard drive volume is the inaccessibility of the data stored on that particular volume. To access the data stored on that volume, the best possible way is to restore the data from an up-to-date backup. However, if there is no backup available or the backup is not enough to restore your desired data, then you will need to use advanced HP-Unix data recovery application that can successfully recover your lost data.

As a practical example, you encounter the following error message when you try to mount your HP-Unix-based system:

“vxfs fsck: File system had metadata I/O errors.

now playing record

filesystem not clean, full fsck required

pass0 – checking structural files

pass1 – checking sanity and inode blocks

vxfs fsck: fsck read error bno=237640, off=0, len=8192

filesystem check failed, aborting…”

The above error message appears every time you try to mount your system.

Cause:

The root cause of the above error message, as stated in the error message, is input/output errors on the file system.

Resolution:

The best way to resolve HP-Unix operating system file system corruption is to run the FSCK command (also suggested in the error message). However, in this case, the FSCK command will not be able to resolve the problem because the command cannot resolve input/output errors. Here are two ways to overcome the above problem:

Change the hard drive.

Reinstall the HP-Unix operating system.

In the event of a fresh reinstallation of the HP-Unix operating system, all data stored on the hard drive is erased. To recover data from formatted hard drive partition, you will need to use HP-Unix Data Recovery application. These HP-Unix recovery applications use powerful scanning methods to recover data from formatted hard drive partitions. Such recovery applications are designed by highly talented engineers and are incorporated with highly graphical user documentation that makes them easy to understand and implement.

Stellar Phoenix HP UNIX – Data Recovery is an efficient HP-Unix recovery software that supports HP-UX file versions like HP-UX 10.x, 11 and 11i. It is installed on Windows (2003, XP, 2000, NT3.51 and above, ME, 9x) and the affected HP-UX hard drive must be connected as a slave.
