SUNW.ScalDeviceGroup Extension Properties

debug_level

This property specifies the level to which debug messages from the resource of this type are logged. When the debug level is increased, more debug messages are written to the log files.

Data type: Integer

Default: 0

Range: 0–10

Tunable: Any time

diskgroupname

This property specifies the name of the device group that the resource represents. You must set this property to one of the following items:

  • The name of an existing Solaris Volume Manager for Sun Cluster multi-owner disk set. This name was specified in the metaset(1M) command with which the disk set was created.

  • The name of an existing VxVM shared-disk group. This name was specified in the Veritas command with which the disk group was created.

The requirements for the device group that you specify are as follows:

  • The device group must be a valid, existing multi-owner disk set or shared-disk group.

  • The device group must be hosted on all nodes that can master the resource.

  • The device group must be accessible from all nodes that can master the scalable device group resource.

  • The device group must contain at minimum one volume.

Data type: String

Default: No default defined

Range: Not applicable

Tunable: When disabled

logicaldevicelist

This property specifies a comma-separated list of logical volumes that the fault monitor of the resource is to monitor. This property is optional. If you do not specify a value for this property, all logical volumes in the device group are to be monitored.

The status of the device group is derived from the statuses of the individual logical volumes that are monitored. If all monitored logical volumes are healthy, the device group is healthy. If any monitored logical volume is faulty, the device group is faulty.

The status of an individual logical volume is obtained by querying the volume's volume manager. If the status of a Solaris Volume Manager for Sun Cluster volume cannot be determined from a query, the fault monitor performs file input/output (I/O) operations to determine the status.

If a device group is discovered to be faulty, monitoring of the resource that represents the group is stopped and the resource is put into the disabled state.


Note - For mirrored disks, if one submirror is faulty, the device group is still considered to be healthy.


The requirements for each logical volume that you specify are as follows:

  • The logical volume must exist.

  • The logical volume must be contained in the device group that the diskgroupname property specifies.

  • The logical volume must be accessible from all nodes that can master the scalable device group resource.

Data type: String array

Default: ""

Range: Not applicable

Tunable: Any time

monitor_retry_count

This property specifies the maximum number of restarts by the process monitor facility (PMF) that are allowed for the fault monitor.

Data type: Integer

Default: 4

Range: No range defined

Tunable: Any time

monitor_retry_interval

This property specifies the period of time in minutes during which the PMF counts restarts of the fault monitor.

Data type: Integer

Default: 2

Range: No range defined

Tunable: Any time
