DEFINE CHPID / PATH
130 z/VM: CP Commands and Utilities Reference
DEDICATED_NOT_REConfigurable
tells CP that this is an unshared channel path which can only be configured or
deconfigured to the logical partition specified on the ACCESS_LIST operand.
Note: This operand is only valid for processors in LPAR mode.
DEDICATED_REConfigurable
tells CP that this is an unshared channel path which can only be configured to
one of the logical partitions specified on the ACCESS_LIST operand at a time.
Later, you can use the MODIFY CHPID or PATH command to reconfigure this
channel path to one of the other logical partitions specified on the
ACCESS_LIST operand.
Note: This operand is only valid for processors in LPAR mode.
SHAREd
tells CP that this is a shared channel path which can be concurrently configured
to any or all of the logical partitions specified on the ACCESS_LIST operand.
Also, multiple logical partitions can have initial access to the channel path at
device initialization.
Note: This operand is only valid for processors in LPAR mode for CBP, CBS,
CFP, CFS, CNC, CTC, DSD, EIO, FC, FCP, FCV, ICP, IQD, ISD, OSA,
OSC, OSD, or OSE channel paths.
ACCess_list pname
specifies the name(s) of the logical partition(s) in which the channel path can be
configured in the specified or implied channel-subsystem image. The maximum
number of logical partition names you can specify depends on the capabilities
of your processor. Each pname must be a 1- to 8-digit character alphanumeric
string. See Usage Note 1 for more information on the maximum number of
logical partitions you can specify.
Note: This operand is only valid for processors in LPAR mode.
INITial_access pname
specifies the name(s) of the logical partition(s) that will have initial access to
this channel path in the specified or implied channel-subsystem image. Each
pname must be a 1- to 8-digit character alphanumeric string. See Usage Note 1
for more information on the maximum number of logical partitions you can
specify.
Note: This operand is only valid for processors in LPAR mode.
MANaged
indicates that the channel path being defined is to be managed by one or more
z/OS systems in other logical partitions comprising an I/O cluster. A managed
channel path is shared among all logical partitions having access to it, but none
have initial access. z/OS dynamically reassigns the channel path within the I/O
cluster according to the workload demands within the cluster.
Note: This operand is only valid for CNC, FC, or FCV switched channel paths.
IOCluster iocname
is the name of the I/O cluster to which the managed channel path is assigned.
The variable iocname must be a 1- to 8-character alphanumeric string.
Note: This operand is valid only for EMIF-capable processors.
