Due to changes in the boot methodology introduced by Solaris 10 Update 6, the BMR restore methodology for Solaris 10 clients has been changed as it relates to the use of an SRT, both for the Prepare to Restore operation as well as the actual restore.  This includes both network based boot restores and media based boot restores.

For Solaris clients at Solaris 10 Update 6 or later, an SRT of level Update 6 or later is required.  An SRT created at level Update 5 or earlier will fail to properly restore the client.  New code introduced for this issue may also cause error messages to appear for the Prepare To Restore operation.

A client kernel level will determine what update is noted by BMR for this. Using the command "uname -a" will show the kernel level for the client.  As an example:

# uname -a
SunOS atxsol108 5.10 Generic_137137-09 sun4u sparc SUNW,Sun-Fire-480R

The kernel value of 137137-09 is the first released level of Solaris 10 Update 6. Any value of this level or higher indicates an update 6 or Update 7 release. Those clients require an SRT of Solaris 10 Update 6 or higher to be properly restored.  See related Tech Notes 322801 and 323877 for details as well.

If the noted kernel level is lower than 137137-09, then the client is Solaris 10 Update 5 or lower.  For those clients you must use an SRT that was created using Update 5 or earlier media.

Lastly, in order to create the SRT for Solaris 10 Update  6 or later, the BMR Boot Server must also be upgraded to Solaris 10 Update 6 or later and have the appropriate EEB patch files installed.  A properly installed BMR Boot Server installed with Solaris 10 Update 6 can create an SRT at the Solaris 10 Update 7 release.
