Figure 1-3: Paircreate Command
Options
(continued) The -vl (-pvol) specifies the local instruction, that is, an instruction to copy a
local instance LU (P-VOL) to a remote instance LU (S-VOL) and to maps a
copying destination volume (a volume of the remote instance) to the local
instance LU (P-VOL).
The -vr (-svol) specifies the remote instruction, and copies data from a
remote instance LU (P-VOL) to a local instance LU (S-VOL) and maps a copy
destination volume (a volume of the local instance) to the remote instance LU
(P-VOL).
Note: This option cannot be specified with “-split” option in the same
command.
-jp <PID> -js <PID>: This is necessary when TCE is used. The options can
be specified by TCE only. The number (data pool ID) of a data pool used by a
P-VOL is specified with the -jp option and that used by an S-VOL is specified
with the -js option.
Note: The -jp and -js options are enabled when the fence level is specified as
“async.” When the -jp and -js options are omitted, 0 is used as a data pool ID.
-pid <PID> (SnapShot only): This option specified the data pool number
(data pool ID) which the pair to create uses. When one P-VOL configures a pair
with two or more V-VOLs, the pair configured by the same P-VOL needs to use
a common data pool. If this option is omitted, 0 is used as a data pool ID.
Returned
values Normal termination: 0. When creating groups, 0 = normal termination for all
pairs. 
Abnormal termination: Returns a common error code and a unique error code
for this command. For details on error codes, see Chapter 2, Troubleshooting .

Parameter Value
NOTE: During TrueCopy and TCE pair operations, there are cases where
pair operation fail when high volume host I/O or frequent change of pair
status is occurring on both local and remote array. If a pair operation fails
and pair status does not change, retry the pair operation (pairvolchk
command can be used to check pair status). If a pair operation fails
partially when doing pair operation by groups, then the operation must be
performed for each pair within that group.
