2.3 Points to consider when setting up a RAID Manager environment

This section explains the points to consider when setting up a RAID Manager environment. For details about setting up a RAID Manager environment, see the RAID Manager documentation.

Organization of this section: (1) RAID Manager administrator; (2) Instance; (3) RAID Manager's command execution environment

(1) RAID Manager administrator

For HiRDB to send queries to RAID Manager, you must assign RAID Manager administrator privileges to the HiRDB administrator.

(2) Instance

The paired volumes on which the update copy target files are located must be operated as a single instance. Although you can specify any number for the instance number, if the system is combined with ShadowImage (HOMRCF), specify a number that is different from the instance number used for ShadowImage. Specify the instance number in the HORCMINST operand. When doing this, specify the same number at the main site and the remote site.

(3) RAID Manager's command execution environment

For HiRDB to issue a RAID Manager command to query the state of TrueCopy or Universal Replicator, you must set up the environment so that a RAID Manager command issued from HiRDB can function as a TrueCopy or Universal Replicator command.
