Description

Disks 

A list of raw disk devices. Use the absolute or relative device path. 

The absolute or relative device path allows a maximum of 64 characters. The relative path is assumed to start from the /dev directory. 

The order of the disks in the list must be the same across all systems in the cluster, even if the same device has a different name on different systems. 

Note   You must change this attribute before bringing a resource online. An online device must be taken offline before altering this attribute because disk reservation occurs during the process of bringing a resource online.

Type and dimension: string-vector 

Example: "sdd"

Description

FailFast 

If enabled, FailFast causes the system to panic when a reservation conflict is detected, reducing the chance of further data corruption. 

Type and dimension: boolean-scalar 

Default: 0 

 

Percentage 

Minimum percentage of configured disks that can be reserved before a resource can go online. The percentage must be greater than or equal to 51, and less than or equal to 100. 

If the value specified is less than 51, the percentage is set to 51. 

If the value specified is greater than 100, the percentage is set to 100. 

Type and dimension: integer-scalar 

Default: 100 

 

ProbeInterval 

Alters the periodicity (in seconds) of the automatic probe function that checks the reservation status of the disks. The value must be greater than or equal to three, and less than or equal to 15. 

If the value specified is less than 3, the interval is set to 3. 

If the value specified is greater than 15, the interval is set to 15. 

A lower value for ProbeInterval specifies more frequent probes and provides for quicker discovery of reservation conflicts. Symantec recommends a value is between 3 and 8. 

Type and dimension: integer-scalar 

Default: 3
