-m grp
[CTG ID]
If CTG ID is not

registered to the
consistency
group. If CTG ID
is specified, a
pair is
registered to the
CTG ID in use.
You can specify
this option.
You can specify
this option.
ShadowImage pairs and
ShadowImage for
Mainframe pairs cannot
be registered to the
same CTG ID. If both
ShadowImage pairs and
ShadowImage for
Mainframe pairs are
registered to one
group, the command
ends abnormally.
pairsplit
-r
-rw
Specifies access
mode to S-VOL
after splitting a
pair.
-r: Read only
-rw: Read/
write enabled
The volume
cannot be read
regardless of the
specified options.
This option is only for
TrueCopy, TrueCopy for
Mainframe, Universal
Replicator, and
Universal Replicator for
Mainframe.
You cannot specify this
option in ShadowImage
or ShadowImage for
Mainframe.
*If the capacity of the S-VOL is larger than that of the P-VOL, you cannot create a pair with CCI. To
create a TrueCopy for Mainframe pair with volumes that differ in capacity, use Business Continuity
Manager or Storage Navigator.
Notes:
•
A mainframe primary volume can also be called a source volume or a main volume.
•
A mainframe secondary volume can also be called a target volume or a remote volume.
