Kernel patches in Solaris operating system are chiefly installed to increase the performance and remove the bugs. While kernel patches provide lots of benefits, installing these patches might also consequence into an error message. Once the error message appears, the system becomes unbootable making all the data saved on the hard excursion far away. To resolve such issues, a perfect solution is to restore the data from an up-to-date backup. However, if no backup is obtainable or backup fails to restore the desired information, then you need to use efficient Sun Solaris Sparc Recovery Software.
As a functional case, you install Solaris 10 kernel patches 137137-09 (SPARC) on your system. After the installation is finished,
“Nov 16 12:52:41 beetle reboot: rebooted by root
Creating boot_archive for /var/run/.patch_root_loopbackmnt
15+0 records in 15+0 records out
Nov 16 12:53:03 beetle ufs: NOTICE: alloc: /: file system complete

syncing file systems… done
Rebooting with command: boot
Warning: Fcode ordern resulted in a net stack thoroughness change of 1
The file just loaded does not appear to be executable.”
After the above error message appears, the system become unbootable and the data saved on the hard excursion becomes far away.
The root cause for the occurrence of the above error message is change in the boot architecture due to installation of kernel patches. The above error message chiefly occurs on SPARC systems where there is less than 550MB of free space in the root file system.
To resolve the above error and access the data, you need to follow these steps:
1. Boot your computer from the network/CD/DVD using a Solaris 10 05/08 (or later).
2. Mount the root filesystem slice to /
3. rm -f //platform/’uname -m’/boot_archive
4. //sbin/bootadm -a update_all
However, if the above steps fail to resolve the issue and the data nevertheless remains far away, then you need to use powerful Sun Solaris Sparc Data Recovery Software to retrieve your data. Such Sun Solaris Sparc Recovery tools use high end scanning mechanisms to retrieve your data. These recovery applications retrieve your data after fsck is unable to repair the system data structures.
Stellar Phoenix (Solaris – Sparc) software is a powerful Sun Solaris Data Recovery utility that recovers data from Solaris operating system on Sparc platform. This non destructive recovery tool supports UFS file systems. It gets installed on Windows (XP, 2003, 2000, NT, ME, 98 and 95) and the affected UNIX hard excursion should be connected as slave.
