Synchronous waiting command (pairsyncwait)
Table 1-38 lists and describes the pair synchronization waiting command
parameters and returned values. The pairsyncwait is a command exclusive
for TCE. It is a command to check whether or not the data written
immediately after the issue of the command is reflected on the S-VOL of the
remote site. This command gets the latest sequence # of local array (P-VOL
latest sequence # within the CT group) and the sequence # of remote array
within the CT group which correspond to the <group> or <raw_device>
that is specified by pairsyncwait, and compares local array with remote
array sequence # at that time and at regular interval. Because the sequence
number is updated for each group, you can check whether the S-VOL data
has been updated or not by executing the command specifying a group
when all the pairs in the target group are in the PAIR status.
If remote array sequence # is over the value of local array sequence #
within the term that was specified by pairsysncwait, this command reports
the return code 0 with the meaning of completion of synchronization. The
–nowait option shows the latest sequence # (Q-marker) of local array P-VOL
and CTGID. The marker is shown in hexadecimal of ten characters.

Options -h: Displays help, usage, and version information.
-q: Terminates the interactive mode and exits the command.
-z or -zx: Makes the raidvchkscan command enter the interactive mode. The
-zx option guards performing of the HORCM in the interactive mode. When
this option detects a HORCM shut down, interactive mode terminates.
-I[H | M][instance#] or -I[TC | SI][instance#]: Specifies the instance
number and the command execution environment. Refer to
Instance number
and option for command execution environment on page 1-4 .
-g <group>: Specifies a group name defined in the configuration definition
file. The command is executed for each CTG unless the -d <pair Vol> option
is specified. The execution result of the pairsyncwait command for each
option, see
Table 1-39 and Table 1-40 .
-d <pair Vol>: Specifies a paired logical volume name defined in the
configuration definition file. When this option is specified, the command is
executed for the specified paired logical volumes.
-d[g] <raw_device> [MU#]:
Searches a group on the configuration
definition file (local instance) for the specified raw_device, and if the specified
raw_device is contained in the group, the target volume is executed as the
paired logical volume (-d) or group (-dg). This option is effective without
specifying the “-g <group>“ option. If the specified the raw_device is
contained in two or more groups, the command is executed on the first group.
