Symptoms

On a system running Solaris Volume Manager (SVM), all mirrors show a state of "Needs Maintenance" after rebooting the system. This occurs on all mirrors on the system, including the root disk if that is under SVM control.  The mirrors can be returned to the "Okay" state by using the metasync command as shown in the output of metastat. However, when the system is rebooted, the mirrors return to a state of "Needs Maintenance".

Note: This document is not applicable for a "Needs Maintenance" status resulting from genuine hardware problems or any system errors other than those described below.


An example of this condition is seen in the output of the metastat command:
