NOTE:
the remote site's device address domain ID.
Do not specify the local site's device address domain ID or the local site's Non
Gen'ed device address domain ID.
If a site is being used as a local site by another Business Continuity Manager
agent, you cannot specify it for use as a remote site.
NOTE:
Do not specify a nonexistent prefix or device address domain ID in the
PREFIX parameter. Even though specifying a nonexistent prefix or device
address domain ID does not result in an error during Business Continuity
Manager agent startup. An error will occur during an P9000 Replication
Manager request.
In the PREFIX parameter, do not specify any value other than the prefix of
the configuration file. If multiple datasets correspond to the specified prefix
(such as the SYS1 prefix), Business Continuity Manager agent processing might
slow down.
If you specify the same prefix multiple times for MODE(MONITOR), the
monitoring processing of P9000 Replication Manager might slow down. If you
specify the same prefix multiple times for MODE(EDIT), an error will occur and
you will be unable to start the Business Continuity Manager agent.
If you specify multiple PREFIX parameters, it will take time to switch the
configuration files for each prefix during an P9000 Replication Manager
request. If there are many configuration files, HP recommends that you
aggregate prefixes in the configuration to one. This will to shorten the access
time for a request.
To modify a configuration file that has a prefix specified in the PREFIX
parameter, make sure you use the ISPF panel or P9000 Replication Manager.
If you use another method, information might not be displayed on P9000
Replication Manager, or an error might occur.
The access time for an P9000 Replication Manager request or response
becomes longer with the number of copy pairs defined in the copy group
definition file that has the specified prefix. Specify the monitoring interval of
P9000 Replication Manager to fit the environment (the host capability
corresponding to the number of copy pairs).
DEVN(start-device-number,end-device-number) ~ <4 hexadecimal characters>
Specifies a range of devices from which to collect information when filtering the
host volume information to be passed to P9000 Replication Manager. Specify the
start-device-number and end-device-number in the ascending order of hexadecimal
characters. If the DEVN parameter has not been specified before,
DEVN(0000,FFFF) is assumed.
Notes about Specifying the DEVN Parameter
To reduce the access time required for requests and replies from P9000
Replication Manager, HP recommends that you specify a range of target
devices from which information is collected.
When you specify more than one DEVN parameter, even if there are duplicate
devices, they are not eliminated, so make sure you avoid specifying such
duplications.
