A two-digit value ranging from 01 to FF specifying the Global
Mirror session number.
VOLSER
Specifies the six-digit MVS volume number of the device to be used for I/O. When LSSTYPE(FB) is
specified, this is a six-character MVS volume serial number of the device to be used as a CKD access
device for I/O. This must be an online System z® volume
located in the same cluster as the LSS where the command is directed. VOLSER is
mutually exclusive with DEVN.
LSSTYPE
Specifies the type of LSS, FB or CKD. If the device(s) being joined
or removed from the global mirror session are fixed block, LSSTYPE(FB)
must be specified. CKD is the default.
LSSNBR
Specifies the two-digit hexadecimal LSS number (00-FF) targeted
by this command. For CKD devices, this must be the same LSS where
the volume specified by the VOLSER keyword resides.
ESSSERIAL
Specifies the 12-digit storage control number targeted
by this command.
ACTION
Specifies the action to be performed:
JOIN
Add device(s) to Global Mirror session.
REMOVE
Remove device(s) from Global Mirror session.
VOLLIST
Specifies a list of two-digit CCA (CKD device) or LUN (Open device) numbers to be added
to or removed from the Global Mirror session. Up to 256 cca or lun numbers may be specified,
separated by commas. This parameter is mutually exclusive with VOLRANGE, MTVOLLIST or MTVOLRANGE.
VOLRANGE
Specifies a list of two-digit CCA (CKD device) or LUN (Open device) ranges to be added
to or removed from the Global Mirror session. The first cca or lun is the beginning of the range,
and the second, separated by a colon, is the end. Up to 256 cca or lun pairs may be specified,
separated by commas. This parameter is mutually exclusive with VOLLIST, MTVOLLIST or MTVOLRANGE.
MTVOLLIST
Specifies a list of Global Copy device numbers to be added to or removed from the Global Mirror
session.
pcca
Specifies the primary CCA (or LUN)
secser#
Specifies the serial number of the secondary device's SFI for the Global Copy pair
slss
Specifies the LSS number of the secondary device for the Global Copy pair
scca
Specifies the CCA (or LUN) number of the secondary device for the Global Copy pair
Specify up to 255 device sets. Use a comma to separate the values in a
set, and use a blank to separate sets, for example: MTVOLLIST(C4,000000016191,3A,C4
C5,000000016191,3A,C5). This parameter is mutually exclusive with MTVOLRANGE, VOLLIST and
VOLRANGE. When there are multiple secondaries, you must use MTVOLLIST or MTVOLRANGE.
MTVOLRANGE
Specifies a list of primary device ranges in an LSS to be added to or removed from the
Global Mirror session.
pcca1:pccax
Specifies the first and last primary CCA (or LUN) in a range of contiguous primary devices. The
first and last CCA indicated are separated by a colon.
secser#
Specifies the serial number of the secondary device's SFI for the Global Copy pair
slss
Specifies the LSS number of the secondary device for the Global Copy pair
scca1
Specifies the first CCA (or LUN) of the secondary device for the Global Copy pair. The last
secondary CCA is derived from the number of devices specified in the pcca1-pccax
range.
Specify up to 255 device sets. Use a comma to separate the values in a
set, and use a blank to separate sets, for example: MTVOLRANGE(C4:CF,000000016191,3A,C4
A0:BF,000000016191,30,A0 E0:E4,000000017720,D0,E0). This parameter is mutually exclusive
with MTVOLLIST, VOLLIST, and VOLRANGE. When there are multiple secondaries, you must use MTVOLLIST
or MTVOLRANGE.
DEVN
Specifies the 4-digit hexadecimal address of the device to which the I/O operation is directed.
DEVN is mutually exclusive with VOLSER.
