Recurring Volume Attachments tab
Recurring Volume Attachments specify which Volumes should be attached to a Server the next time that it is launched. All of the Servers to which a Volume is scheduled to be attached at boot time are displayed in the "Recurring Attachments" tab of the Volume itself.
Runnable - The Server or Server Array to which a Volume attachment is attached or scheduled to be attached.
Runnable Type - Either "Server" or "Server Array", depending on what is Runnable.
Device - If a Volume is attached to an instance, the system identifier of the block device as it is manifested on the running Server is displayed. (If known and reported. For example, "/dev/sdj" ) If the Device of the Volume is not known it is labeled as such along with a unique/random number. Example: unknown_1438:1235.
Size - Size of the Volume in gigabytes. (For example, 10 GB.)
