seq.split.with.LUN.create

Severity

ALERT

Description

This message occurs when the SnapMirror Synchronous sequential split is enabled and a LUN create operation is encountered. LUN create operations are blocked since sequential split is meant to be enabled for NAS workloads only. SAN operating workloads experience a higher latency and it is not recommended that they be used with sequential splitting mode.

Corrective Action

Switch back to parallel split mode by running the command (priv: advanced) "snapmirror policy modify -policy (policy name) -are-data-ops-sequentially-split false" or opt to use system default policies of Sync and StrictSync for the Snapmirror Synchronous relationship.

Syslog Message

LUN create Operation encountered with sequential splitting enabled for relationship with UUID "%s".

Parameters

relationship_id (STRING): SnapMirror relationship universal unique identifier (UUID).
