8.3.2 Starting a session

This section shows the commands to start a replication session.

flashess command

To run a created or terminated Point-in-Time Copy session invoke flashsess command:

flashsess [-quiet] session_name [. . .]

412 Managing Disk Subsystems using IBM TotalStorage Productivity Center

session_name

specifies the session name to be activated. Separate multiple session names with a

white space between each name. Alternatively, use the dash (-) to specify that input for

this parameter comes from an input stream (STDIN).

-quiet

An optional parameter that turns off the confirmation prompt for this command.

Example 8-3 shows an example of the flashess command.

Example 8-3 flashsess command

repcli> flashsess -quiet FC_F20_800

AWN007110I Command completed successfully.

To start a created, terminated or suspended Continuous Synchronous Remote Copy session

invoke the startsess command as shown in Example 8-4:

Example 8-4 startsess command

repcli> startsess PPRC_800_to_F20

AWN007100I Command completed successfully.

Example 8-5 shows the status of started sessions. Point-in-Time Copy was created

successfully which confirms normal status and yes value of recover parameter. However,

Continuous Synchronous Remote Copy is running (Active State) but not synchronized which

show in the Recover and Status parameters.

Example 8-5 lssess - started sessions

repcli> lssess

Name Status State Group Type Recover Shadow Err

================================================================

PPRC_800_to_F20 warning Active PPRC_src pprc No Yes No

FC_F20_800 normal Active FC_src flash Yes Yes No

lsseq command

You should use two additional commands lsseq and lspair to get more details about current

state of sessions.

lsseq [ { -l |-s } ] [-recov yes|no] [-shadow yes|no] [-err yes|no] session_name

-s

An optional parameter that displays volumes only.

-l

An optional parameter that displays all valid output. This is the default.

-recov yes | no

An optional parameter that indicates whether any sequences in the session can be

considered recoverable.

-shadow yes | no

Note: In a batch program use the quiet parameter where available, otherwise the program

will wait for your confirmation.
