Command execution modes

RAID Manager provides two command execution modes: transaction mode that executes by

specifying a script file with -zt option, and line-by-line mode that executes a command row-by-row

for the configuration setting commands (raidcom commands). The transaction mode can execute

the following checking.

• Context check: This check is executed when a script file is specified by -zt option. It checks

the context of preceding commands and determines whether a subsequent command can be

executed.

Specifying example:

> raidcom -zt <script_file>

• Configuration check: This check verifies that the actual storage system confirmation is valid

(implemented) for the resources specified in the commands (LDEVs, ports, pools, etc.).

Syntax example:

> raidcom get ldev -ldev_id -cnt 65280 -store<work_file>

> raidcom -zt <script_file> -load<work_file>

Precheck function

RAID Manager provides a precheck function that checks a configuration command before executing

the command for the configuration setting commands (raidcom commands):

In previous versions of RAID Manager, an error was returned when the syntax of a command to

be executed was not correct. Now the precheck function checks the command syntax before the

command is issued. To use this function, specify either the -checkmode precheck option or the

-zt option.

The following table shows the checking function combinations between the precheck function and

the transaction mode.
