Solaris 10 Kernel Patches are primarily installed to remove all the firmware problems and software bugs. In most cases, you are benefited with installation of Solaris Kernel Patches. However, there can be instances where your system becomes unbootable after installing these patches. Furthermore, your hard drive data becomes inaccessible once your system becomes unbootable. For complete recovery of inaccessible data after such instances, you will need to restore the data from an updated backup. However, if no backup is available or backup falls short to restore the desired information, then you will need to opt for advanced Solaris Intel Recovery Software that can systematically recover your data.

Consider a practical scenario, where you install a patch 120586-04 (MP1) on Solaris 10 systems running VXVM 4.1 patch. However, after you install the new patch and restart your system, you view that your system hangs every time during a boot up. In addition, you encounter the below error message:

Boot device: disk File and args:
Loading ufs-file-system package 1.4 04 Aug 1995 13:02:54.
FCode UFS Reader 1.12 00/07/17 15:48:16.

Cause:

The above error message primarily occurs when svccfg(1M) removes the External Dependencies.

Resolution:

To resolve the above error message and access the hard drive data, you will need to manually re-import the “/var/svc/manifest/system/emcpower/powerpath_services.xml” manifest. You will also need to complete the below steps:

svcadm disable -s powerconfigcgs
svcadm disable -s powershift
svcadm disable -s powerstartup
svccfg delete powerconfigcgs
svccfg delete powershift
svccfg delete powerstartup
svccfg import /var/svc/manifest/system/emcpower/powerpath_services.xml
svcadm enable powerstartup
svcadm enable powershift
svcadm enable powerconfigcgs

But, if the above resolution fails to remove the issue and your system still remains unbootable, then you will need to use advanced Solaris Intel Recovery Software. These Sun Solaris Data Recovery tools use effective scanning methods to recover your lost data after serious corruption scenarios like superblock corruption, inode structure damage, etc. With highly graphical user-interface, to the point documentation, these tools are easily understandable without former data recovery experience.

Stellar Phoenix (Solaris - Intel) Data Recovery is an efficient Sun Solaris Data Recovery software. This non destructive recovery application is compatible with UFS file systems. It gets installed on Windows (XP, 2003, 2000, NT, ME, 98 and 95) and the affected Sun Solaris hard drive is connected as slave.
