HP XP24000/XP20000 for FlashCopy Mirroring Software User Guide (T5240-96012, November 2011)

Figure 62 Set SCP Time Dialog Box
The following items are displayed in the Set SCP Time dialog box:
• SCP Time(sec.) text box specifies the state-change-pending time in seconds (0 to 600 seconds).
The text box displays the state-change-pending time that is set to the CU selected in the FCv2
window by default. If multiple CUs are selected and the state-change-pending time that is set
to each CU is different, the text box will be blank by default.
• The OK button closes the SCP Time dialog box and displays the changed state-change-pending
time in the FCv2 window. Note that if the SCP Time(sec.) text box is blank, the setting in the
SCP Time dialog box is invalid.
• The Cancel button cancels the setting in the SCP Time dialog box and closes the dialog box.
Releasing a Version 2 Relationship
The following sections explain how to use various commands to withdraw Version 2 relationships.
You can use the FCESTABL command of the PPRC TSO commands, ICKDSF commands, or
ANTRQST macro commands to withdraw Version 2 relationships. See the following sections for
specific instructions:
• Page 105
• Page 117
• Page 120
CAUTION: When many FlashCopy relationships are withdrawn at the same time for the storage
system shared with IBM OS and Fujitsu OS, the time-out will occur. Therefore, when planning to
withdraw a quantity of FlashCopy relationships, divide the tasks into small groups to minimize
time-out issues.
For instance, when you release 100 relationships or more, you should release relationships at
intervals of about five seconds per 100 relationships.
Releasing a Version 2 Relationship Using the TSO Command
The FCWITHDR command can be used to withdraw relationships established for copy operations
set either in COPY or NOCOPY mode.
CAUTION: If you use the FCWITHDR command a single time when deleting numerous
relationships, a timeout may occur on the host. Therefore, use the FCWITHDR command more than
one time when deleting a large number of relationships. After you execute the FCWITHDR command
one time, wait for a period of time before you execute the command again. For example, if you
execute the FCWITHDR command one time when deleting more than 700 relationships, wait for
approximately 5 seconds before you execute the command again.
(page 106) shows the parameters you can use with the FCWITHDR command when you release
Version 2 relationships.
