IPLing the system

7 IPL the system.

Use the new I/O configuration definition that contains the library tape drive definitions to IPL the system. This also activates the OAM1 subsystem. The system issues the following messages and you can use them to verify a successful IPL of the system.

CBR8001I OAM1 subsystem initialization starting.

Note: If your installation is not using OAM to store objects, and is strictly using OAM for tape library management, ignore the following messages when they are displayed during IPL:

CBR8007I No DB2 SSID or the DB2 SSID value of "NONE" has been specified. OTIS subsystem cannot successfully initialize.

CBR8002I OAM1 subsystem initialization completed.

Devices Unavailable at IPL: If message IEA438I is issued during system IPL indicating that devices were not available during the IPL process (perhaps they were in use on another system), perform the following steps:

Issue the MVS VARY command to vary the devices online.
Issue the ACTIVATE command to activate the IODF containing the devices that were unavailable.

If your installation is using OAM for object support (DASD, optical, or tape), See z/OS DFSMS OAM Planning, Installation, and Storage Administration Guide for Object Support for more information.
