To transfer a copy of this file to the virtual reader of the OSVSSYS virtual machine, enter the following commands:
cp specl punch to osvssys
punch initstrt ojcl (noheader)
These commands queue the punched file in the virtual reader of user OSVSSYS, whether OSVSSYS is· logged on or not. If OSVSSYS is logged on
and does not have its messages disabled (SET !SG OFF), a message at the
terminal netifies him of the additional reader input. If OSVSSYS is not
legged on, the notification message is displayed as part of the user's
LOGON messages when he eventually logs on.
Tc perform the initialization, use a second terminal and log on to
userid OSVSSYS. Send the following messages to the system operator: msg op Fls mount scratch 3330 pack as 350 msg op pIs mount osvs1 starter tape as 181
In response tc these messages, the system operator mounts a 3330 volume
on some available disk drive, such as 150, and enters:
attach 150 to osvssys as 350 Similarly, after mounting the VS1 starter tape on an available tape
drive, such as 411, he enters:
attach 411 to osvssys as 181
The user receives the following
operator's action:
DASD 350 ATTACHED TAPE 181 ATTACHED
two messages to confirm the From the OSVSSYS terminal the user can now enter these CP commands to
load the IBCDASDI program: ready 181
ipl 181
ihen loaded, IBCDASDI is the first file on the starter tape. After
being loaded, the program goes into a wait state. To check for this
wait state condition, display the PSi by issuing:
icp display psw
To define the control statement input device (the virtual reader) to
the IBCDASDI program, press the ENTER key (or its equivalent) to display
this message:
IBC105A DEFINE INPUT DEVICE Reply, in uppercase: INPUT=2540,OOC ihen the vclume initialization is complete, the user receives this message at his terminal:
IBC163A END OF JOB After displaying this message, the system enters the wait state.

RESTORING THE STARTER SYSTEM TO DISK As performed for the IBCDASDI program, a user at the OSCMS terminal can
create a CMS file for the IBCDMPRS program and punch it to the virtual
reader of the OSVSSYS virtual machine. The starter tape is now positioned at the end of the first file and ready to load the second
file, the IBCDMPRS program. Use the OSVSSYS terminal to enter the
command:
ipl 181
To define the control statement input device to the program, follow
the same prccedure as in the volume initialization step. When the user
receives the END OF JOB message, the starter system has been restored to
the DASD voluae and can now be made operational. LOADING THE STARTER SYSTEM Tc start the interim starter system, enter the following command frow the OSVSSYS terminal:
ipl 350 clear When the user receives this message: IEA760A SPECIFY VIRTUAL STORAGE SIZE Enter a null line if the virtual machine size is less then 384K. For
the 768K machine used in this discussion. enter! R 00,'2048' Ccntinue replying to the prompting messages as directed in the apprcpriate system generation publication. When the user receives this message: IEE0481 INITIALIZATION COMPLETED Ready the starter system to process input, and enter the following
co.mands to start normal system operation: MN JOBNAMES,T START RDR,OOC START WTR,OOE START INIT.PO",A RESTORING DISTRIBUTION LIBRARIES TO DISK Ask the systea operator to mount a scratch pack as virtual address 351
tc contain the distribution libraries: #cp msg cp pIs mount scratch 3330 pack as 351
At the OSCMS terminal, create the IEHDASDR control statement file for
initializing the volume. Then, punch the file to the OSVSSYS machine
for executicn. Before executing the IEHDASDR utility program, vary the DASD volume offline. Section 4. OS/VS in a Virtual Machine 119
