Technical Solution



Due to the method by which Bare Metal Restore (BMR) gathers disk special device file information, the permissions of these files will be reset to default values by the "bmrsavecfg" program.


NetBackup 7.1.0.X HP/UX clients will encounter this condition.


The BMR process "bmrsavecfg" is invoking a native HP/UX command with an invalid option.  The effect of this command option is to reset the file permissions of the disk device special files to default values of "bin/sys".


This is a known issue and is fixed by Engineering binary for under ET 2623649 and for under ET 2961971. Please contact Symantec NetBackup support to request this binary fix.  In the interim, you can reset the file permission to their normal settings using the "chmod" command and disabling BMR disaster recovery information collection on the backup policy.
