Informix Error -752: All Smart Disk devices are busy.

Reasons / Common Causes

-752 fires when every configured Smart Disk device is currently busy and can't accept the requested operation — per the official guidance, the documented resolution is simply to wait and retry.

1. Peak concurrent load on the Smart Disk subsystem, with every device occupied by other operations at the moment this request was made.
2. A genuinely undersized Smart Disk configuration for the workload, if this recurs regularly rather than being an occasional peak-load condition.

Solutions / Resolution

1. Wait a while and retry the operation, per the official guidance — the documented, specific resolution.
2. Implement a retry-with-backoff pattern in application code, if this condition is encountered programmatically, rather than failing the operation outright on the first occurrence.
3. If this recurs frequently, review Smart Disk device utilization and configuration with whoever administers the Smart Disk subsystem, since occasional busy-and-retry is expected behavior but frequent recurrence suggests a capacity issue.

Examples

A simple retry pattern

-- On -752, wait briefly and reissue the same Smart Disk operation,
-- per the official guidance.

Diagnostic Checks

1. Check how frequently -752 occurs — occasional occurrences are expected under peak load; frequent occurrences suggest a capacity issue worth reviewing with the Smart Disk administrator.
