san.slmSupportCheckFailed

Severity

ERROR

Description

This message occurs during reboot when SAN capability is enabled, the cluster has more than 8 nodes and lun.reporting.nodes options is disabled. It leads to host instability as the number of paths exposed exceeds the threshold that the host stacks can handle.

Corrective Action

Set the option "lun.reporting_nodes.enable" to "on" with the command "vserver options lun.reporting_nodes.enable on" and enable Selective LUN Map on existing maps with the command "lun mapping add-reporting-nodes -vserver * -path * -igroup * -local-nodes".

Syslog Message

Clusters with more than 8 nodes must have SLM support enabled.

Parameters

(None).
