3. After the volumes were fully copied, we suspended the pairs; see Example 21-5.

4. We could verify whether the volumes were suspended with the CQUERY command. State
SUSPEND(3) means that the Global Copy volume pair was suspended by a host
command to the primary site storage control. In Example 21-6, we show the results for
device
6030 .

5. After the pairs were suspended, we resumed the I/O on the primary site and made a
FlashCopy on the secondary site. We made an inband FlashCopy of the secondary
volumes using the FCESTABL command; see Example 21-7. We requested inband
FlashCopy with the REMOTE(YES) parameter. The DEVN parameter specifies the
address of the Global Copy primary volume. The SOURCE and TARGET parameters
specify the FlashCopy source and target volumes. SSID is the Subsystem Identifier of the
FlashCopy source volume. This must be the same value as that specified for SSID of the
secondary device on the PPRC CESTPAIR command.
Example 21-7 Make FlashCopy
FCESTABL DEVN(6030) SOURCE(AAVCA 00 30) TARGET(AAVCA 00 40) REMOTE(YES) -
SSID(0002) MODE(COPY)
