Symptom & Impact

On IBM AIX 7.2, startsrc -s sshd returns 0513-095 record already exists surfaces in errpt and user-facing services, risking outage and SLA breach until the startsrc path is corrected.

Environment & Reproduction

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

Root Cause Analysis

Root cause for startsrc -s sshd is typically ODM drift, LVM metadata mismatch, fileset state, or subsystem misconfiguration exposed by startsrc on IBM AIX 7.2.

Quick Triage

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

Step-by-Step Diagnosis

Drill into startsrc -s sshd with errpt -aj , lslpp -L, startsrc-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 startsrc/smit remediation for startsrc -s sshd, 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 startsrc -s sshd 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 startsrc -s sshd 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 startsrc -s sshd cannot silently re-emerge on IBM AIX 7.2.

Related Errors & Cross-Refs

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