Chapter 3 Notes
78
(7) Upon failure of unmounting, CHKDSK /F /X is executed with mount point volume name
specified. “\” at the end of mount point volume name must be omitted in the name specified for
CHKDSK.
(8) If you execute replication or disk operation from the terminal service client, the operation is not
guaranteed.
(9) The difference backup system that operates archive bits is not available for making RV data
backup copies in a tape unit.
(10) In cluster environment, install ReplicationControl in both servers of the operating system and
standby system. The servers cannot share the environment setting. Set up environment for
each server.
(11) In cluster environment, use the iSMrc_signature command for all the disks that are to be
replication target disks of the operating system in order to get and save (export) the disk signature
information and import the information in the standby system. (Replication target disks are
disks with the disk signature already written.) If disk signature information such as cluster
failover is lost, it can be restored.
(12) In cluster environment, the RV that moved into the Not Ready state at execution of Replicate or
Restore needs to be recognized as a faulty disk. You cannot use RV as a shared disk of
CLUSTERPRO in a system configuration including CLUSTERPRO.
(13) Executing the iSMrc_umount command to unmount a shared disk of MSCS (Microsoft Cluster
Server) may cause failover. Therefore, do not execute Unmount for the shared disk. To obtain
the static point of data at execution of Separate, stop the application, and then execute the
iSMrc_flush command to flush the disk and wait for completion of delayed updating. Before
executing Restore, unmount the disk while the MSCS service is in stopped state.
If DynamicDataReplication is used in a system configuration including MSCS (Microsoft Cluster
Server), you can use MV as a shared disk, but not RV. You cannot place a quorum disk of
MSCS on MV, either.
(14) A physical disk number may be changed by the SCSI device driver’s Plug and Play function
during system operation. Therefore, except for the iSMrc_signature command, the volume
specification that uses a physical disk number is not supported by the ReplicationControl Ver2.1
and later. If the physical disk number has changed causing inconsistency between the state of
the system device and volume list information, re-create the volume list.
(15) The iSMrc_editdl command is not supported by the ReplicationControl Ver2.1 and later. To set
and cancel the drive letter, use the Windows standard MOUNTVOL command.
(16) On Windows Server 2003, use the MOUNTVOL command provided by the operating system to
disable automatic volume mounting (MOUNTVOL /N) before operation.
(17) When using ReplicationControl Ver3.2 or later, specify NOTREADY for the
UMOUNT_RVACC parameter in the replication operation option setting file to suppress
automatic RV mounting. Before applying this setting, take note of the following points then
check and review the operation procedures as required:
