Symptom & Impact

instfix shows missing filesets on clients even though lpp_source advertises the SP.

Environment & Reproduction

Happens when filesets were added to lpp_source without running nim -o check.

Root Cause Analysis

NIM database does not see new filesets until the lpp_source is re-validated.

Quick Triage

Run lsnim -l lpp_sourcename and look at last_unavail and update fields.

Step-by-Step Diagnosis

Compare actual directory contents under /export/lpp_source with the NIM catalog.

Solution – Primary Fix

Run nim -o check lpp_sourcename and nim -o update -a packages=all lpp_sourcename.

Solution – Alternative Approaches

Recreate the lpp_source from a fresh service pack download if check still fails.

Verification & Acceptance Criteria

lsnim shows alloc_count and bos.rte at the expected SP level for clients.

Rollback Plan

Remove the broken lpp_source with nim -o remove and restore from a backup definition.

Prevention & Hardening

Automate lpp_source updates with nim -o check after every fileset drop.

Related Errors & Cross-Refs

Tied to nim-client-install-fails and emgr-ifix-conflict.
