Define a configuration definition file
Define HORCM_LDEV or HORCM_DEV of the configuration definition files of the primary and
secondary volumes. For definition details, see
(page 24) .
A device name is a name given to an LDEV in each device group.This is equivalent to the dev_name
definition of HORCM_DEV. A device name is not required, but it is convenient to use to specify
device group or device name instead of LDEV number. However, to create a pool or a journal,
specifying LDEV number is required.
The LDEVs that have the same device name are recognized as a pair in the primary and secondary
device group. Therefore, make match the device name for the LDEV to be a pair. Also, the number
of LDEVs in the device group must be the same at the primary and secondary sides. Pairs are
operated in the ascending sequence of the LDEV numbers. If there is no corresponding device
name of LDEV in the device group to be paired, an error might be occurred on the pair operation.
Read operations and command device settings
When grouping LDEVs, if HORCM_LDEVG on the primary side and secondary side is not defined,
the read operation of RAID Manager is different depending on the command device settings. The
following table shows the details.
