Solaris : Missing or Lost path_to_inst file in Sun Solaris operating system

/etc/path_to_inst file is one of the most critical file for the computer system to boot. Corruption of this file primarily occurs due to improper system shutdown, operating system malfunctioning and virus infection and more. Once the above file gets corrupted due to any of the above reasons, the system becomes unbootable making all the data stored in the hard drive inaccessible. To overcome such data loss scenarios, an up-to-date backup acts as a boon. However, if no backup is available or backup fails to restore desired information, then you will need to use advance Sun Solaris Intel Recovery Software.Consider a practical scenario, where you encounter the below error message when you attempt to boot your system:“can not open /etc/path_to_inst file”Data saved in the hard drive becomes inaccessible after the above error message appears. Furthermore, you receive the same error message each time you attempt to boot your system.Cause:Two major reasons for the occurrence f the above error message are discussed below:Hardware failure with the root disk.Corruption or damage in root filesystem Resolution:To resolve the above error message and access the data, you need to follow these actions:Replace the hard disk in case of hardware failure.In case of root file system damage, you will need to rebuild the file by using below steps:1. Firstly, try to boot your system with –ar option as follows:ok> boot -ar 2. Next, you will need to press Enter for all the questions asked during the booting process.3. Lastly, select “Yes” to rebuild the “/etc/path_to_install” file.In most cases, the above steps resolve the above error and the data becomes accessible. However, if the steps fail to perform, then you will need to reinstall Sun Solaris operating system. A clean reinstall of Sun Solaris erases all the data saved in the selected hard drive partition. For comprehensive recovery of data under such situations, you will need to use advanced Sun Solaris Intel Recovery Software. Such Sun Solaris  Data Recovery utilities are built with interactive user interface, which makes them self-explanatory without any prior technical understanding. Stellar Phoenix (Solaris – Intel) software is the best Sun Solaris Intel Data Recovery utility that completely recovers data from Solaris operating system on Intel platform. This non destructive recovery utility supports UFS file systems. It gets installed on Windows (XP, 2003, 2000, NT, ME, 98 and 95) and the affected UNIX hard drive should be attached as slave.
