DEFINE B Use the DEFINE co •• and to redefine the status of a 3330V volume. For exaaple, a 3330V .ay have been defined as VIRTUAL allowing it to be
dedicated to a specific virtual .achine. However, if that virtual
.achine is not logged on, you can redefine the 3330V as SYSVIRT to make it available to the control prograa for .ounting system voluaes. The
for.at of the DEPINE co.mand is: DEPine { SYSVirt} Virtual raddr1 [-raddr2] _____________________________________________________________ ---J SYSVIRT specifies the desired status of the 3330V. This
reserved for CP. V8/370 system volumes that are voluaes can be aounted on SYSVIRT 3330V devices.
status is ftSS 3330V VIRTUAL specifies the desired status of the 3330V. 3330V devices that
are dedicated or attached aust use the VIRTUAL feature.
raddr1 [-raddr2]
specifies the device address or range of addresses to be
defined. If a range is specified, all 3330V devices in the
range are set to the desired status. !!sage Notes:
If an 8SS voluae is aounted and not currently in use on a 3330V that is
redef1ned, the control program cuases the voluae to be demounted before
the DEFINE co •• and coapletes. An 8SS volume deaount should be forced to
redefine the status of the 3330V on which the volume is aounted.
Responses are sent to the operator who issued the DEFINE coamand. The
responses show the device status following execution of the command. Possible responses are:
raddr NOT KNOWN The raddr is not a valid device address. No action is taken for
the raddr.
raddr NOT 3330V The raddr is not a 3330V. No action is taken for the raddr.
raddr ALREADY SYSVIRT raddr ALREADY VIRTUAL The raddr already has the status to which it is to be defined. It
is left in its current status. raddr IS CURRENTLY DEDICATED
The raddr is currently dedicated to a virtual machine. The status
is not changed froa VIRTUAL to SYSVIRT. 62 V8/370 Operator's Guide

raddr IS OFFLINE. DEFINE WILL BE DONE. The raddr is currently offline. When it is varied online, it viII receive the status specified in the co •• and.
raddr IN USE BY SYSTEM The raddr is currently attached to the system and there is at least
one user .inidisk allocated on the volu.e. The raddr cannot be
defined as VIRTUAL. raddr HAS A MOUNTED VOL. MSS ID NOT AVAILELE TO DEMOUNT IT
There is a 3330V volume .ounted on the raddr. The ftSS co.municator
is not active and the voluae cannot be de.ounted. The status of
the raddr is not changed.
raddr - ERROR DEftOUNTING VOLUME There is a 3330V voluae aounted on the raddr. The control progra.
attempted to demount the volume, but ftSS encountered an error. The volume is not demounted and the status of the raddr is not changed. INVALID RANGE A range of address (raddr1 -raddr2) vas sFecified. Either raddr1
or raddr2 does not exist or is not a 3330V. Status is not changed.
raddr DEFINED AS VIRTUAL raddr DEFINED AS SYSVIRT The raddr has been given the specified status. a voluae vas
previously mounted on the raddr, it is nov demounted. Section 3. CP Commands 63
