Volume management makes volume sets available as soon as they are physically recognized by the system. The system automatically recognizes a volume set after the volumes have been added to the volume set, upon the power on of the disk drive, or at the boot of the system.
In order to access data from a volume set, only the volumes where the data is located and the master of the volume set need to be mounted. The system volume set master (LDEV 1) must be mounted on the disk drive at all times. Nonsystem volumes sets are not necessary to system operation and can be removed or replaced online without affecting system operation. This means that a nonsystem drive can fail without bringing down the system.
No mount command is needed to access the volume set. However, there are system mount commands that are used to notify the system that you want the volume set to remain physically mounted for a period of time. The system mount commands are described in chapter 5.
As long as the I/O path to the device has been configured, any volume set may be mounted on any system. A maximum of 32 volume sets may be mounted on the system at one time.
