Symptom & Impact

lsvg shows STALE physical partitions and applications report read errors.

Environment & Reproduction

Mirrored LVs lost a copy after a transient hdisk failure on AIX 7.2.

Root Cause Analysis

syncvg has not run since the disk recovered.

Quick Triage

Run lsvg -l rootvg and look for ‘stale’ in the STATE column.

Step-by-Step Diagnosis

Use lsvg -p rootvg to find which PV holds stale PPs and lspv -l hdiskN to map them.

Solution – Primary Fix

Resync with syncvg -v rootvg or syncvg -p hdiskN to fix only one disk.

Solution – Alternative Approaches

Remove the bad mirror copy with rmlvcopy LVNAME 1 hdiskN if the disk is dead.

Verification & Acceptance Criteria

lsvg -l reports no STALE partitions and lspv shows both copies in sync.

Rollback Plan

Re-add the mirror later with mklvcopy LVNAME 2 hdiskN; syncvg -l LVNAME.

Prevention & Hardening

Schedule periodic syncvg and monitor with errpt for LVM_SA events.

Related Errors & Cross-Refs

Often paired with LVM_SA_QUORCLOSE or DISK_ERR errpt entries.
