Cómo comprobar los puntos de montaje globales

El comando sccheck(1M) permite realizar comprobaciones que examinan el archivo /etc/vfstab en busca de errores de configuración con el sistema de archivos del clúster y sus puntos de montaje globales.

Nota –

Ejecute sccheck después de efectuar cambios en la configuración del clúster que afecten a dispositivos o a componentes de gestión de volúmenes.

Pasos

Conviértase en usuario root en cualquiera de los nodos del clúster.
% su

Verifique la configuración del clúster.
# sccheck

Ejemplo 1–9 Comprobación de los puntos de montaje globales

En el ejemplo siguiente se muestra que al nodo phys-schost-2 del clúster suncluster le falta el punto de montaje /global/schost-1. Los informes generados se envían al directorio de salida /var/cluster/sccheck/myReports/.

# sccheck -v1 -h phys-schost-1,phys-schost-2 -o /var/cluster/sccheck/myReports

sccheck: Requesting explorer data and node report from phys-schost-1.
sccheck: Requesting explorer data and node report from phys-schost-2.
sccheck: phys-schost-1: Explorer finished.
sccheck: phys-schost-1: Starting single-node checks.
sccheck: phys-schost-1: Single-node checks finished.
sccheck: phys-schost-2: Explorer finished.
sccheck: phys-schost-2: Starting single-node checks.
sccheck: phys-schost-2: Single-node checks finished.
sccheck: Starting multi-node checks.
sccheck: Multi-node checks finished.
sccheck: One or more checks failed.
sccheck: The greatest severity of all check failures was 3 (HIGH).
sccheck: Reports are in /var/cluster/sccheck/myReports.

CHECK ID : 3065
SEVERITY : HIGH
FAILURE  : Global filesystem /etc/vfstab entries are not consistent across 
all Sun Cluster 3.x nodes.
ANALYSIS : The global filesystem /etc/vfstab entries are not consistent across 
all nodes in this cluster.
Analysis indicates:
FileSystem '/global/phys-schost-1' is on 'phys-schost-1' but missing from 'phys-schost-2'.
RECOMMEND: Ensure each node has the correct /etc/vfstab entry for the 
filesystem(s) in question.

FAILURE  : An unsupported server is being used as a Sun Cluster 3.x node.
ANALYSIS : This server may not been qualified to be used as a Sun Cluster 3.x node.  
Only servers that have been qualified with Sun Cluster 3.x are supported as 
Sun Cluster 3.x nodes.
RECOMMEND: Because the list of supported servers is always being updated, check with 
your Sun Microsystems representative to get the latest information on what servers 
are currently supported and only use a server that is supported with Sun Cluster 3.x.
