To initialize a 3350 in native mode after conversion from 3330 or 3340 compatability mode, the device must be attached (dedicated) to a virtual
machine and either IEHDASDP or IBCDASDI must be run. This is necessary
to allow alternate cylinders to be formatted and alternate tracks
assigned.
The JOB statement indicates the beginning of a job. The format of the JOB statement is:
r I( name] I JOB I[user information] L- ___________________________________________________________________________ The KSG statement defines an output device for operator messages. It
follows the JOB statement and precedes any function-defining state.ents
that are associated with the IBCDASDI program. The format of the KSG statement is: I I[ name 1 TODEV=xxxx TOADDR=CUu I KSG I TODEV=xxxx,TOADDR=cuu is the device type of the message output device (1403, 1052,2400,3400,3210, or 3211).
is the channel number (c) and unit number (uu) of the
message output device.

The DADEP statement defines the direct access vcluae to be initialized. The format of the DADEP statement is:
r [nalle] DADEP' I TODEV=xxxxxx I,TOADDR=cuu I[,IPL=YES] 1{,VOLID=serial } I ,VOLID=SCRATCH 1[,!ODEL=n] 1[,CYLIO=nnn] 1

2Applies to initialization with surface analysis.
3Applies to initialization without surface analysis. TODEV=xxxxxx TOADDR=cuu IPL=YES is a 4-to 6-character device type of the direct access Specify either: 2305 2314 3340 for 3340 and 3344 3330 for 3330 !odels 1 or 2 and 3350 in 3330-1 coapatibility mode 3330-1 for 3330 Model 11 and 3350 in 3330-11
coapatibility aode 3350 in native mode is the channel (c) and unit address (uu) of the device. Specify the real address of the device if you are executing IBCDASDI on the real aachine; specify the virtual address of
the device if you are executing IBCDASDI on the virtual
aachine.
writes an IPL prograa on the minidisk. In IPL initialization program must be written on a device to be used for systea
residence. If IPL is oaitted, no IPL prograa is written. lot!: If you specify IPL=YES, you aust also include an IPLTXT statellent. VOLID=serial
is the voluae serial nuaber of the ainidisk to be initialized.
If "serial" aatches the voluae serial number found on the
ainidisk to be initialized, the operation proceeds. If it
does not aatch, the operator is notified. VOLID=SCRATCH specifies that no voluae nuaber check is to be aade.
