ProcedureVérification des points de montage globaux

La commande sccheck(1M) comprend des contrôles qui permettent de rechercher les erreurs de configuration du fichier /etc/vfstab avec le système de fichiers de cluster et ses points de montage globaux.

Remarque –

exécutez la commande sccheck si vous avez apporté à la configuration de cluster des modifications ayant une incidence sur les périphériques ou les composants de gestion des volumes.

Étapes

  1. Devenez superutilisateur sur un noeud du cluster. 


    % su

  2. Vérifiez la configuration du cluster. 


    # sccheck
Exemple 1–9 Vérification des points de montage globaux

L'exemple suivant montre qu'il manque le point de montage /global/schost-1 au nœud phys-schost-2 du cluster suncluster. Des rapports sont transmis au répertoire de sortie /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.

CHECK ID : 1398
SEVERITY : HIGH
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.
