– Shadowing - No - sequence is not shadowing

– Exception volumes - 0 - no volume is in exception state

– Recoverable pairs - 0- no pair is recoverable

– Shadowing pairs - 0 -no pair is shadowing

– Total pairs - 2 - total number of pairs is two

– Recoverable timestamp - n/a, recovery is not possible so there is no time information

Notice that state is Suspended but a session is not recoverable.

In a Sequence states panel you see that two pairs are in Suspended state but the

Recoverable value is false. To see more details, select Sequence in Sequences panel and

click Pairs. A new window opens as shown in Figure 8-74.

8.3 Using Command Line Interface (CLI) for replication

This section introduces the command-line interface (CLI) for TotalStorage Productivity Center

for Replication. We will focus on main commands used for managing session. See IBM

TotalStorage Productivity Center for Disk and Replication: Command-Line Interface User’s

Guide, SC30-4109, for detailed description of all available commands.

Using the CLI you can create, delete sessions, groups, pools and related copy pairs as well

as run, suspend and terminate replication sessions. You can use CLI installed together with

TotalStorage Productivity Center for Replication on main server or install CLI on other

machine and invoke commands remotely. See “Installing CIM agent for ESS” on page 124 for

installation instructions.

repcli utility

To use the CLI you have to run the repcli utility. The default folder location of CLI for

Replication Manager is c:\Program Files\IBM\mdm\rm\rmcli. This utility can also run

commands in interactive mode, single command or a set of commands from a script.

Syntax of repcli command:

repcli [ { -ver|-overview|-script file_name|command | - } ] [ { -help|h|-? } ]

where

-ver

Displays the current version

-overview

Displays the overview information about the repcli utility, including command modes,

standard command and listing parameters, syntax diagram conventions, and user

assistance.

-script filename

Runs the set of command strings in the specified file outside of a repcli session. You

must specify a file name. The format options specified using the setoutput command

apply to all commands in the script. Output from successful commands routes to

stdout. Output from unsuccessful commands route to stderr. If an error occurs while

one of the commands in the script is running, the script exits at the point of failure and

return to the system prompt.

example:

repcli -script start_backup.scr

-command_string

Runs the specified command string outside of a repcli session.

example:

repcli lssess
