Symptom & Impact

Print jobs pile up; qchk shows queues in DOWN state.

Environment & Reproduction

Triggered by a network printer being moved or renamed.

Root Cause Analysis

qdaemon cannot reach the backend rembak host for the queue.

Quick Triage

Run enq -As and qchk -A to list queue states.

Step-by-Step Diagnosis

Inspect /var/spool/lpd/qdir and tail /var/spool/lpd/stat/sqdir.

Solution – Primary Fix

Re-enable with enable -A and refresh -s qdaemon after fixing hosts.

Solution – Alternative Approaches

Alternative: recreate the queue with smit mkpq using the new address.

Verification & Acceptance Criteria

Verify qchk -A shows READY and a test page prints successfully.

Rollback Plan

Backup /etc/qconfig before editing queue definitions.

Prevention & Hardening

Standardise queue names and use DNS, not IPs, in /etc/qconfig.
