Setting up a tape library as an alternate IPL device

Use the devices in a tape library for alternate initial program load (IPL) when they are attached to an input/output processor (IOP) and input/output adapter (IOA) in a position that supports an alternate IPL.

The devices must be set to the correct address.

You can use alternate installation for tape libraries that are attached to an IOP and IOA even if the alternate installation is not in a position that supports alternate IPL.
