Symptom & Impact

On IBM AIX 7.2, errpt floods with SC_DISK_ERR2 entries on hdisk1 surfaces in errpt and user-facing services, risking outage and SLA breach until the errpt path is corrected.

Environment & Reproduction

Reproduce on IBM AIX 7.2 LPARs by exercising the errpt workflow that triggers errpt floods with, then capture errpt -a, oslevel -s, and lssrc -a output with timestamps.

Root Cause Analysis

Root cause for errpt floods with is typically ODM drift, LVM metadata mismatch, fileset state, or subsystem misconfiguration exposed by errpt on IBM AIX 7.2.

Quick Triage

Run errpt | head, lssrc -a, lsvg -o, svmon -G, and df -g to confirm errpt floods with scope before mutating ODM or LVM on the IBM AIX 7.2 host.

Step-by-Step Diagnosis

Drill into errpt floods with with errpt -aj , lslpp -L, errpt-specific queries, and smit fast paths; record evidence in a IBM AIX 7.2 change ticket before remediation.

Solution – Primary Fix

Apply the least-invasive errpt/smit remediation for errpt floods with, refresh -s the affected subsystem, then re-run errpt and lssrc on IBM AIX 7.2 to confirm clean state.

Solution – Alternative Approaches

If the primary fix is blocked, fall back to ODM rebuild, varyoff/varyonvg, mksysb restore of the affected filesets, or LPAR reboot during a IBM AIX 7.2 maintenance window.

Verification & Acceptance Criteria

Accept when errpt is clean, lssrc shows active, lslpp -L reports COMMITTED, application probes pass, and errpt floods with does not recur for one full IBM AIX 7.2 business cycle.

Rollback Plan

Keep a current mksysb plus alt_disk_copy snapshot; save ODM (/etc/objrepos) and modified config files so any errpt floods with remediation on IBM AIX 7.2 can be reversed within minutes.

Prevention & Hardening

Schedule errpt monitoring, lssrc/lslpp drift checks, paging/svmon thresholds, and quarterly mksysb tests so errpt floods with cannot silently re-emerge on IBM AIX 7.2.

Related Errors & Cross-Refs

Cross-reference related errpt labels, IBM APARs, and adjacent errpt/LVM/subsystem issues to short-circuit triage on future errpt floods with incidents.
