If we query the volumes 6500 and 6501, that are in the storage disk subsystem at site 1, and
have target volumes 6500 and 6501 in the storage disk subsystem at site 2, we will see the
result shown in Example 26-56.

26.11.3 Query FlashCopy pairs
Query the FlashCopy relationships with the DS CLI command lsflash. The syntax of the
lsflash command is as follows:
dscli lsflash -cfg <Device configuration file> <Source_Volume>:<Target_Volume>
<Source_Volume>:<Target_Volume> ...
If we list FlashCopy information for source volumes 6500 and 6501, which have corresponding
target volumes 6502 and 6503 on the storage disk subsystem at site 2, we see the results
shown in Example 26-57.
Example 26-57 lsflash command output
dscli lsflash -l -cfg $DSCLI/profile/DS-02.profile 6500:6502 6501:6503

26.11.4 Query volumes in the session
The lssession command is used to display Global Mirror session information regarding the
volumes in each session. Issue this command to query the status of all volumes that are
associated with the sessions of a specified LSS.
The syntax of the lssession command is as follows:
dscli lssession <LSS_ID> -cfg <Device configuration file>
To list the volumes in LSS 65, see Example 26-58 on page 397. Note that the volumes are not
participating in the Global Mirror session, they are in a
because they have not yet completed their initial copy first pass.
