Do not edit the configuration definition file while RAID Manager is running. Shut down RAID
Manager, edit the configuration file as needed, and then restart RAID Manager.
Do not mix pairs created with the "At-Time Split" option (-m grp) and pairs created without this
option in the same group defined in the RAID Manager configuration file. If you do, a pairsplit
operation might end abnormally, or S-VOLs of the P-VOLs in the same consistency group (CTG)
might not be created correctly at the time the pairsplit request is received.
Configuration definition file settings
(1) HORCM_MON
The monitor parameter (HORCM_MON) defines the following values:
•
Ip_address: The IP address of the local host. When HORCM has two or more network addresses
on different subnets for communication, this must be set to NONE.
•
Service: Specifies the UDP port name assigned to the HORCM communication path, which is
registered in "/etc/services" ("\WINNT\system32\drivers\etc\services" in Windows,
"SYS$SYSROOT:[000000.TCPIP$ETC]SERVICES.DAT" in OpenVMS). If a port number is
specified instead of a port name, the port number will be used.
•
Poll: The interval for monitoring paired volumes. To reduce the HORCM daemon load, make
this interval longer. If set to -1, the paired volumes are not monitored. The value of -1 is specified
when two or more RAID Manager instances run on a single machine.
•
Timeout: The time-out period of communication with the remote server.
(2) HORCM_CMD
When using the in-band method, this command parameter (HORCM_CMD) defines the UNIX
device path or Windows physical device number and specifies a command device that can access
the RAID Manager.
The detailed are described in the following.
