34 Storage agents Volume Manager Diskgroup (VMDg) agent Table 2-6 VMDg agent optional attributes (continued) Optional Attributes ListApplications Description Defines whether the agent lists the applications accessing the disk group while deporting. The value 1 indicates the agent lists the applications. The value 0 indicates it does not. Default is 0. Note: The list of applications can be seen in the agent's log. Type and Dimension: boolean-scalar ListMountedVolumes Defines whether the agent lists all mounted volumes in the disk group. The value 1 indicates the agent lists the mounted volumes. The value 0 indicates it does not. Default is 0. Note: The list of mounted volumes can be seen in the agent's log. Type and Dimension: boolean-scalar VxObFailAction This attribute has been deprecated. Use VxSVCFailAction instead. Type and Dimension: string-scalar VxObRestartAttempts This attribute has been deprecated. Use VxSVCRestartAttempts instead. Type and Dimension: integer-scalar VxVMFailAction This attribute has been deprecated. Use VxSVCFailAction instead. Type and Dimension: string-scalar VxVMRestartAttempts This attribute has been deprecated. Use VxSVCRestartAttempts instead. Type and Dimension: integer-scalar VxSVCFailAction Defines the agent behavior when the <strong>Veritas</strong> Storage Agent service (VxSVC) fails. The value RESTART_VXSVC indicates the agent attempts to restart the VxSVC service every monitor cycle. The value SHUTDOWN indicates the agent attempts to restart the VxSVC service the number of times defined in the attribute VxSVCRestartAttempts. If it fails in restarting VxSVC, the agent shuts down the system. When this occurs, all service groups online on the system fail over to another system in the cluster. For example, if VxSVCRestartAttempts is set to 5, the agent attempts to start the service five times before shutting down the system. Default is RESTART_VXSVC. Type and Dimension: string-scalar
Storage agents MountV agent 35 Table 2-6 VMDg agent optional attributes (continued) Optional Attributes VxSVCRestartAttempts Description The number of times the agent attempts to restart the failed VxSVC service before shutting down the system. This attribute is considered only when VxSVCFailAction is set to SHUTDOWN. Default is 10. Type and Dimension: integer-scalar FastFailOver This attribute decides whether or not a disk group is enabled for fast failover. The value 1 indicates that the agent enables fast failover for the configured disk group. The value 0 indicates that fast failover is disabled for the disk group. Default is 0. Type and Dimension: boolean-scalar Sample configuration VMDg DG_VCSDG ( DiskGroupName = VCSDG ListMountedVolumes = 1 DGGuid = fb69e244-930f-479e-b9f5-c54449fe2fc0 ) MountV agent The MountV agent mounts, monitors, and unmounts volumes on cluster disk groups imported using the <strong>Veritas</strong> Storage Foundation for Windows. The agent supports volumes formatted using the NTFS, FAT, and FAT32 file systems. When a cluster disk group fails over to another system, the MountV agent ensures the new system accesses the volume in the same way it was accessed before failover. The MountV agent ensures a consistent device path by mounting the disk group with the same mount point (drive letter) on the new system. The agent also mounts a volume as an NTFS folder. The agent ensures proper dismounting from a failed system when a resource or group is taken offline. When a volume is mounted, VCS creates an administrative share to enable remote administration of the disk. The agent performs a file system check when it brings the resource online. If a drive letter is already assigned to the volume, the agent skips the file system check, and declares the resource online. Note that the volume to be monitored using the MountV agent must not be mounted multiple times.
