Solaris : How to resolve UNEXPECTED INCONSISTENCY
Solaris : How to resolve UNEXPECTED INCONSISTENCY
An error message during the booting of Sun Solaris operating system can be caused due to file system corruption, operating system malfunctioning, superblock damage, Inode table corruption, software bugs and more. Once the error message appears, the booting process stops making all the data saved in the hard drive inaccessible. To overcome these error messages, the best solution is to restore the data from an updated backup. But, in case of no backup availability or backup falling short of restoring desired information, Sun Solaris Intel Recovery Software comes to rescue.Consider a practical example, where you encounter the below error message when you attempt to boot Sun Solaris operating system:/dev/rdsk/variable: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLYâData stored in hard drive becomes inaccessible after the above error message appears. In addition, you encounter the same error message each time you attempt to start your system.Cause:The root cause for the occurrence of the above error message is corrupted UFS (Unix File System). At the boot time, the /etc/rcS scripts run the fsck (1M) command to check the integrity of UFS. In case of corrupted file system, the fsck command tries to repair the file system automatically. However, if the command is unable to repair the file system then it interrupts the boot procedure and produces an error message. Resolution:To resolve the above error message and access the data saved on the hard drive, you will need to run these commands:1. Firstly, run sack ân on the corrupted file system to analyze the exact problem. 2. Then, run fsck command manually to repair the file system. To run fsck command manually, you will need to specify options as recommended by the boot script. In most cases, running the fsck command manually resolves the issue. However, if the command falls short to resolve the issue and the data remains inaccessible, then you need to opt for advanced Sun Solaris Intel Data Recovery Software to recover the lost data. Such Sun Solaris Data Recovery tools incorporate advanced scanning methods to recover your lost data. Such recovery tools recover lost data after fsck command is unable to repair the system data structures. Stellar Phoenix (Solaris – Intel) software is a reliable Sun Solaris Intel Data Recovery utility that provides complete recovery of data from Solaris operating system on Intel platform. The read only tool is compatible with UFS file systems. It gets installed on Windows (XP, 2003, 2000, NT, ME, 98 and 95) and the affected UNIX hard drive should be connected as slave.
