SUNW.ScalMountPoint Extension Properties

debug_level

This property specifies the level to which debug messages from the resource for a file-system mount point 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

filesystemtype

This property specifies the type of file system whose mount point the resource represents. You must specify this property. Set this property to one of the following values:

nas

Specifies that the file system is a file system on a Network Appliance NAS device.

s-qfs

Specifies that the file system is aSun StorEdge^TM QFS shared file system.

Data type: String

Default: No default defined

Range: Not applicable

Tunable: When disabled

iotimeout

This property specifies the timeout value in seconds that the fault monitor uses for file input/output (I/O) probes. To determine if the mounted file system is available, the fault monitor performs I/O operations such as opening, reading, and writing to a test file on the file system. If an I/O operation is not completed within the timeout period, the fault monitor reports an error.

Data type: Integer

Default: 300

Range: 5–300

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

mountoptions

This property specifies a comma-separated list of mount options that are to be used when the file system that the resource represents is mounted. This property is optional. If you do not specify a value for this property, mount options are obtained from the file system's table of defaults.

• For a Sun StorEdge QFS shared file system, these options are obtained from the /etc/opt/SUNWsamfs/samfs.cmd file.

• For a file system on a Network Appliance NAS device, these options are obtained from the /etc/vfstab file.

Mount options that you specify through this property override the mount options in the file system's table of defaults.

Data type: String

Default: ""

Range: Not applicable

Tunable: When disabled

mountpointdir

This property specifies the mount point of the file system that the resource represents. The mount point is the full path to the directory where the file system is attached to the file system hierarchy when the file system is mounted. You must specify this property.

The directory that you specify must already exist.

Data type: String

Default: No default defined

Range: Not applicable

Tunable: When disabled

targetfilesystem

This property specifies the file system that is to be mounted at the mount point that the mountpointdir extension property specifies. You must specify this property. The type of the file system must match the type that the filesystemtype property specifies. The format of this property depends on the type of the file system as follows:

• For a Sun StorEdge QFS shared file system, set this property to the name that was assigned to the file system when the file system was created. The file system must be correctly configured. For more information, see your Sun StorEdge QFS shared file system documentation.

• For a file system on a Network Appliance NAS device, set this property to nas-device:path. The replaceable items in this format are as follows:

  nas-device

  Specifies the name of the Network Appliance NAS device that is exporting the file system. You can optionally qualify this name with a domain.

  path

  Specifies the full path to the file system that the Network Appliance NAS device is exporting.

  The Network Appliance NAS device and the file system must already be configured for use with Sun Cluster. For more information, see Sun Cluster 3.1 - 3.2 With Network-Attached Storage Devices Manual for Solaris OS.

Data type: String

Default: No default defined

Range: Not applicable

Tunable: When disabled
