for AIXAttributes for HP-UX

Required attributes for HP-UX

Required attribute

Description

DiskGroup 

Name of the disk group that is configured with Veritas Volume Manager. 

Type and dimension: string-scalar 

Example: "diskgroup1" 

 

Optional attributes for HP-UX

Optional attributes

Description

MonitorReservation 

If the value is 1, and SCSI-3 fencing is uses, the agent monitors the SCSI reservation on the disk group. If the reservation is missing, the Monitor agent function takes the resource offline. 

Type and dimension: boolean-scalar 

Default: 0 

 

PanicSystemOnDGLoss 

Determines whether to panic the node if the disk group becomes disabled. A loss of storage connectivity can cause the disk group to become disabled. 

If the value of this attribute is 1 and the disk group becomes disabled, the node panics.  

If the value of the attribute is 0 and the disk group becomes disabled, the following occurs: 

  • If the cluster has I/O fencing enabled, the DiskGroup resource is marked faulted. This state results in the agent attempting to take the service group offline.

    As part of bringing the DiskGroup resource offline, the agent attempts to deport the disabled disk group. Even if disabled disk group fails to deport, the DiskGroup resource enters a faulted state. This state enables the failover of the service group that contains the resource. To fail back the DiskGroup resource, manually deport the disk group after restoring storage connectivity

  • If the cluster does not use I/O fencing, a message is logged and the resource is reported online.

Type and dimension: boolean-scalar 

Default: 1 

 

StartVolumes 

If value is 1, the DiskGroup online function starts all volumes belonging to that disk group after importing the group. 

Type and dimension: string-scalar 

Default: 1 

 

StopVolumes 

If value is 1, the DiskGroup offline function stops all volumes belonging to that disk group before it deports the group. 

Type and dimension: string-scalar 

Default: 1 

 

UmountVolumes 

This attribute enables the DiskGroup resource to forcefully go offline even if open volumes are mounted outside of VCS control. When the value of this attribute is 1 and the disk group has open volumes, the following occurs: 

  • The agent attempts to unmount the file systems on open volumes. If required, the agent attempts to kill all VCS managed and un-managed applications using the file systems on those open volumes.
  • The agent attempts to forcefully unmount the file systems to close the volumes.

Type and dimension: integer-scalar 

Default: 0 

 

TempUseFence 

Do not use. For internal use only. 

 

Reservation 

If the value of the attribute is set to SCSI-3, the disk group is imported with a SCSI-3 reservation. This action requires that the disks support SCSI-3. SCSI-3 reservations ensure that I/O happens only from the node that holds the SCSI-3 reservation. If the value of the attribute is set to NONE, the disk group is imported without reservation. 

Type and dimension: string-scalar 

Default: NONE 

Examples: NONE orSCSI3
