Some noteworthy features, the HP-UX (Hewlett Packard UNIX) operating system from other UNIX improved reliability, security, workload management and partitioning. This was the first UNIX operating system for access control lists for access. Disaster data loss situations in HP-UX on the basis of the disk or the server can be used as Disk0 in the disk array enclosures are not installed. In such cases, the loss of data, an ideal solution for restoring your lost data by using the last backup. However, if you do not back up or back-up is the abbreviation for the recovery of the desired information, you must make advanced HP-UX Recovery complete your application data is lost.
As a practical example, loss of information in HP-UX system by the following sequence of events:
Disk array is shut down.
Disk 0 is any area or not well
Disk array is back.
This disk 0 is replaced in the slot, after the disk array is enabled.
To prevent data loss from HP-UX system, then the following steps:
The removal of SATA drives in a power-down disk-array enclosure, so that all hard drives are fully seated before power again.
Remove either disk 0 when the disk array enclosure, or disk 0 again, the drive array enclosure will create a backup copy.
If, after feeding on an array, you noticed disk 0 is not complete, the power of the array and replace it with a new hard drive, is NOT fit
Resolution:
The best way to protect the data from HP-UX-based hard drive with HP-UX Advanced Data Recovery application. This HP-UX Data Recovery uses a systematic scan of the damaged hard disk with high-end scanning methods. These instruments will be lost following severe corruption scenarios such as super block or inode structure, LVM, Cylinder groups Damage OLT. With the documentation at the point, very graphical user interface and advanced features, these instruments are easy to understand, without any technical knowledge.
