19: 03: 16 START ((COLD I WARM) (DRAIN» I (SHUTDOWN) :cold 19:04:00 FILES: NO RDR, NO PRT, NO PUN issues the messages indicating that CPDRM1 and PIDSK2 are not
mounted because the virtual DMKSYS module has an owned list that has
three volumes specified: CPDRM1, PIDSK2, and PIDSK3. The only one
available in the configuration during IPL was the system residence
vclume, CPDSK3. These error messages are not severe: only a minimum
amount of space is required by cp to accomplish paging and spooling.
The response to the start message in this case is "cold," which should te the normal response unless a specific test of warm start is required. r-- ! 19:04:23 query dasd all 19:04:30 DASD 130 cp 001 19:04:30 DASD 131 FREE 19:04:30 DASD 132 OFFLINE 19:04:30 DASD 133 OFFLINE 19:04:30 DASD 134 OFFLINE 19:04:30 DASD 135 OFFLINE 19:04:30 DASD 136 OFFLINE 19:04:30 DASD 137 OFFLINE 19:04:30 DASD 250 OFFLINE 19:04:30 DASD 251 OFFLINE 19:04:30 DASD 252 OFFLINE 19:04:30 DASD 253 OFFLINE 19:04:30 DASD 254 OFFLINE 19:04:30 DASD 255 OFFLINE 19:04:30 DASD 256 OFFLINE 19:04:30 DASD 257 OFFLINE 19:04:30 DASD 2DO OFFLINE 19:04:30 DASD 2D 1 OFFLINE 19:04:30 DASD 2D2 OFFLINE 19:04:30 DASD 330 CP OWNED PIDSK4 001 19:04:30 DASD 331 CP CPRL10 001 19:04:30 DASD 332 cp SYS196 001 19:04:30 DASD 333 FREE 19:04:30 DASD 334 OFFLINE 19:04:30 DASD 335 OFFLINE 19:04:30 DASD 336 OFFLINE 19:04:30 DASD 337 OFFLINE 19:04:30 DASD 350 OFFLINE 19:04:30 DASD 351 OFFLINE 19:04:30 DASD 352 OFFLINE 19:04:30 DASD 353 OFFLINE L--- Section 2. in a Virtual Machine 63

In this example: The exclamation mark (!) indicates that an attention
has been signaled. VM/370 reflects this signal as an attention to the
virtual machine. The virtual CP system responds to the attention by
typing the time and issuing a read. The response to the read is the
entry of the QUERY DASD command. The response to this command from the
virtual CP system is the DASD status shown. Notice that most of the
devices are in an offline condition, since at the time of the IFL these
device addresses were not available in the virtual machine
configuraticn. The devices that were available are now marked free,
owned, or system. (The system volumes are ones that have minidisks in
use by the operator.) Notice that device 332 has a label of SYS196 in
the virtual CP system. A previous QUERY VIRTUAL showed that DASD 332 is
actually mounted on PIDSK7. However_ this label is the real system label and is not the one recognized by the virtual CP system.
Fer users tc access the 332 disk, the virtual directory must refer to
the virtual label of syS196. (The operator's virtual disk 196 refers to
a zero cylinder displacement on volume SYS196.) 19:06:34 q virtual 19:06:40 STORAGE = 00256K 19:06:40 CONS 009 ON DEV 01F 19:06:40 RDR OOC CLS A 19:06:40 PUN OOD CLS A 19:06:40 PRT OOE CLS A 19:06:40 DASD 190 2314 CMS190 19:06:40 DASD 196 3330 SYS196 COpy 01 COpy 01 RIO 056 CYL RIO 010 CYL L--- ________________________________________ Again, the user signals attention to the virtual CP system. The
oFerator types in QUERY VIRTUAL, and the display is the virtual machine

has a ccnfiguration that is suitable for running CMS by loading (via IPL) virtual device 190. r---- I 19:07:38 att 131 operator 191 I 19:07:55 DASD 131 ATTACH TO OPERATOR 191
The operator attaches what appears to him as real disk 131 to himself
as virtual address 191. The response indicates a successful attach.

virtual 131 disk is a 2314 with read-only status, with 26 usable
cylinders.
