Use this command to define a new recovery log volume. All recovery log volumes must reside on a random access media. You can have TSM create the volume before it is assigned.
Attention: You cannot change the size of an allocated recovery log volume after you have defined it to TSM. If you change the size of TSM volumes TSM may not initialize correctly and you could lose data.
A recovery log volume must be at least 9MB. Storage space is used in 4MB blocks and 1MB is used for overhead purposes. For example, if you define a recovery log volume with a capacity of 9MB, 8MB are available for storage on the volume.
Privilege Class
To issue this command, you must have system privilege or unrestricted storage privilege.
