Symptom & Impact

emgr -e ifix.epkg.Z fails with prerequisite or locked fileset errors.

Environment & Reproduction

Hit when target fileset TL/SP does not match ifix or another ifix conflicts.

Root Cause Analysis

emgr enforces prerequisites and refuses to install over an incompatible base.

Quick Triage

Run emgr -l and lslpp -L bos.rte to verify current TL/SP and existing ifixes.

Step-by-Step Diagnosis

Inspect /var/adm/ras/emgr.log for the exact prerequisite or lock message.

Solution – Primary Fix

Remove conflicting ifix with emgr -r LABEL then retry emgr -e for the new package.

Solution – Alternative Approaches

Update the base TL/SP with update_all from a NIM lpp_source if prereqs require it.

Verification & Acceptance Criteria

emgr -l shows the new ifix as S (stable) and the target fileset is unchanged.

Rollback Plan

Re-install the previous ifix with emgr -e original.epkg.Z if regression appears.

Prevention & Hardening

Stage ifix installs via NIM and test on a clone LPAR before production.

Related Errors & Cross-Refs

Related to TL/SP updates, locked filesets, and lppchk warnings.
