Required Attribute Description, Type and Dimension, Default, and Example

Disks

Specifies, in paired values, the block device (typically a logical volume) and the starting block location to use for the heartbeat. For example, if the block device /dev/vg01/lvol_hb is used for the heartbeat region, and the starting block is 16, the paired set of values is /dev/vg01/lvol_hb, 16.

A block device partition containing one or more heartbeat regions cannot be used for any other purpose. If the same partition is used for more than one heartbeat region, starting block numbers must be at least 64K (128 disk blocks) apart.

  • Type and dimension: string-vector
  • Example:

  • { "/dev/vg01/hb_vol1" , "64" , "/dev/vg01/hb_vol2" }

AllOrNone

Specifies number of disks for which "ownership" is required to bring the resource online, where: all available disks (AllOrNone = 1) and a simple majority of available disks (AllOrNone = 0).
