Commvault IntelliSnap backup failed "snapshot creation failed: array is offline"

TL;DR

The array is offline from IntelliSnap's point of view, which usually means the array's management state, the snapshot engine's view of it, or the connectivity between the MediaAgent and the array: check the array's status in the Commvault array management view, refresh the array's credentials and connectivity, and confirm the array itself reports healthy in its own console. An array mid-firmware-update or with its management interface down reads as offline even while data paths are fine.

Commvault IntelliSnap backup failed "snapshot creation failed: array is offline"

Use this when

• The job or restore fails with this symptom: Commvault IntelliSnap backup failed with snapshot creation failed: array is offline.
• You are working on a Commvault IntelliSnap backup using hardware snapshots and the failure repeats on the same target or schedule.
• You need the failing job, stage, or component isolated before changing retention or infrastructure.

Not for this skill when

• An array that is genuinely offline due to a storage outage, where the fix is the array's recovery rather than Commvault.
• The error text names a different product, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Open array management for the target array and read its status and last error in Commvault. Verify: the array's Commvault-side state is known
2. Check the array in its native console for health, maintenance, or firmware activity. Verify: array-side condition is established
3. Verify the MediaAgent can reach the array's management interface and that stored credentials still authenticate. Verify: management connectivity and auth are proven
4. Refresh the array in Commvault and run a small IntelliSnap job to confirm snapshot creation works. Verify: a test snapshot is created successfully

intellisnap array offline mediaagent management fix

The management phrasing.

commvault hardware snapshot array offline refresh credentials

The refresh phrasing.

Compatibility: Commvault IntelliSnap with hardware array snapshots

Why it happens

IntelliSnap orchestrates the array's own snapshot engine, so the array's management plane is a hard dependency of every job. Offline in this error means unreachable or unresponsive at that plane, a state the array's data services can survive while snapshots cannot.

Edge cases / pitfalls

• Credential rotation on the array side breaks IntelliSnap silently until the next job; update Commvault's stored credentials in the same change.
• Multiple arrays in one job fail per array; the job error names the first, not necessarily the only, offline array.
