Data loss in HP-UX Computer

Few striking features that differentiate HP-UX (Hewlett Packard UNIX) operating system from other UNIX are enhanced reliability, security, workload management, and partitioning. This was the first UNIX operating system that used access control lists for file access permissions. Catastrophic data loss situations in HP-UX based hard drive or server can occur if Disk0 in the disk array enclosures are not installed. In such data loss situations, an ideal solution is to restore your lost data by using the most recent backup. However, if you have not created any backup or backup falls short to restore the desired information, then you will need to use advanced HP-UX Recovery application to completely recover your lost data.As a practical instance, data loss in HP-UX based system occurs after the following sequence of events:Disk array is powered down.Disk 0 from any enclosure is removed or is not seated properlyDisk array is powered back up.The same disk 0 is replaced in is slot after the disk array has been powered on.To prevent data loss from HP-UX system, you will need to follow these steps:When removing SATA disks from a powered-down disk array enclosure, ensure all disks are fully seated before reapplying power.Do not either remove disk 0 when the disk array enclosure is powered down, or reinsert disk 0 after the disk array enclosure is powered back up.If after powering up an array, you noticed disk 0 is out or not fully seated, power down the array and replace this disk with a new disk; DO NOT reseat it.Resolution:The best possible way to recover the data from HP-UX based hard drive is by using advanced HP UNIX Data Recovery application. Such HP-UX Data Recovery applications systematically scan the corrupted hard drive by employing high-end scanning methods. These tools recover lost data post serious corruption scenarios like superblock or inode structure, LVM, Cylinder Grou, OLT damage. With to the point documentation, highly graphical user interface and advanced features, these tools are easy to understand without any prior technical skills.Stellar Phoenix  HP UNIX Data Recovery is a trust worthy HP-UX Recovery application. This non destructive utility is compatible supports HP-UX file versions like HP-UX 10.x, 11 and 11i. It gets installed on Windows (2003, XP, 2000, NT3.51 and above, ME, 9x) and the affected HP-UX hard drive should be connected as slave.
