Stellar Phoenix HP Unix is data recovery software that allows you to recover lost data from the JFS (VxFS) file system of the HP-UNIX Operating System. Data loss in HP-UX is typically caused by corrupt Super Blocks, damaged Inode structures, corrupt LVM, errors in Cylinder groups, and damaged OLT (Object Location Tables). In most of these cases, the FSCK is not able to repair the damaged file structure and data appears to be permanently lost. Phoenix can even recover data after partition table errors and cases of deleted, damaged, repartitioned or missing partitions.
