Establishing Version 2 Relationships while Suspending Write Operations to
S-VOLs
When you establish Version 2 relationships with the FCESTABL command while suspending the write
operations to the S-VOLs in order to keep data consistency, the following parameter is available in
addition to the parameters in Table 34 on page 76 and Table 36 on page 79.
Table 37 Parameters for t h e FCE STABL Command ( Version 2 / Sus pending Write
Operations to S -VOLs)
Parameter
Value
Description
ACTION
FREEZE
Suspend the write operations from the host to the S-VOLs. Note that if you
establish a relationship specifying extents, the ACTION parameter will
suspend the write operation to the whole volume.
Figure 43 on page 82 shows an example of how to use the FCESTABL c ommand to suspend the write
operation to an S-VOL when you establish a Version 2 relationship. In this example, the FC ESTABL
command
establishes a relationship for the volumes (devices) numbered 4202 and 4203, and at the
same time, suspends the write op eration from the host to the source device numbered 4202.

Figure 43 Example of the FCESTABL Command (Version 2 / ACTION Specified)
To resume the write operation to the S-VOLs, you need to issue the FCW ITHDR comma nd with
the
ACTION parameter specified. For detailed information about the FCWITHDR com m a nd, see
“Releasing a Version 2 Relationship Using FCWITHDR”onpage83.
If a timeout occurs, the write operation m ay b e resumed althou gh you do not issue the FCWITHDR
command. The default setting for the timeout is 120 seconds (2 minutes) , but you may change it. To
change the tim eout period (SCP time ):
Caution: Remember that the state-change-pending tim e (SCP tim e) of Version 2 and TrueCopy for
Mainframe is the same. Therefore, when you are going to change the state-change-pending time
of
Version 2, you need to decide on the setting value, considering that the state-change-pending
time of TrueCopy for Mainframe will be also changed to the same value. For information about the
state-change-pending tim e of TrueCopy for Mainframe, see the Hitachi TrueCopy for z/OS User and
Reference Guide.
1. Change the operation mode of Remote Web Console to Modify mode.
2. Display the FCv2 window.
Note: If you are already displaying another window, click the FCv 2 tab. For information about
how to display the FCv2 window directly by starting up Remote Web Console, see the Hitachi
ShadowImage for z/OS User's Guide.
3. In the Tree o n the FCv2 window, select the LDKC that contains the CU for which you want to
change the state-change-pending time.
The list of CUs is displayed on the right.
