Symptom & Impact

startwpar fails or the WPAR enters defined state with errors in /var/adm/wpars/wparname.log.

Environment & Reproduction

Occurs after a WPAR was created on a different TL/SP than the global environment.

Root Cause Analysis

Filesystems for the WPAR are missing, or the global is at a level newer than the WPAR shares.

Quick Triage

Run lswpar -L wparname and inspect /var/adm/wpars/wparname.log.

Step-by-Step Diagnosis

Use chwpar -K to refresh shared filesystems and lswpar -G to confirm settings.
