HP StorageWorks P9000 Replication Manager Software 7.1 CLI User Guide (TB584-96026, May 2011)

• A RAID Manager instance (instance number: 1) has already been activated on the file/database
server.
• A RAID Manager instance (instance number: 2) has already been activated on the backup server.
• RAID Manager configuration definition files (horcm1.conf and horcm2.conf) have already
been created on the file/database server and on the backup server.
In this example, the parameters are specified as follows:
• In the RAID Manager-linkage definition file (DEFAULT.dat) on the file or database server, 1 is
assigned to the parameter HORCMINST as the instance number of the RAID Manager instance
that manages the primary volume and 2 is assigned to the parameter HORCMINST_AUX as the
instance number of the RAID Manager instance that manages the secondary volume.
• In the RAID Manager-linkage definition file (DEFAULT.dat) on the backup server, 2 is assigned
to the parameter HORCMINST as the instance number of the RAID Manager instance that manages
the secondary volume and 1 is assigned to the parameter HORCMINST_AUX as the instance
number of the RAID Manager instance that manages the primary volume.
Specifying a retry count and interval for pair status retry checking
Application Agent determines whether a backup or restoration has finished by checking the status of
the volume pair. By specifying parameters for the retry count and retry interval, you can set the retry
count and retry interval for checking the pair status.
If you need to specify the status checking retry count and interval that are used for backup, restore,
and resynchronization for each pair, you can specify them in the copy parameter definition file. For
details on the copy parameter definition file, see “Specifying a retry count and interval appropriate
to operation style” on page 126.
The pair status checking retry interval should be 1.5 times the estimated pair operation time in a
backup system configuration. By default, Application Agent checks the pair status every five seconds,
up to 120 times. This default setting assumes that a backup or restoration will finish in 10 minutes (5
seconds * 120 = 600 seconds). If backup or restoration does not finish within 10 minutes (because,
for example, a volume is constantly being updated) the backup or restoration command will result in
a timeout error. To prevent this, you must change the default setting.
Table 31 Parameters in the RAID Manager-linkage definition file (default.dat) (to specify the retry
count and retry interval for checking the status of a pair)
Specifiable values
(default)
DescriptionParameter
0 to 3600
(120)
In this parameter, specify the maximum retry count for
checking the status of a pair. If you specify 0, Applica-
tion Agent continues to retry checking until it can check
the status.
RETRY_TIME
0 to 3600
(5)
In this parameter, specify the same number of seconds
as the retry interval for checking the status of a pair.
RETRY_WAIT
The smaller the value of the RETRY_WAIT parameter, the larger the CPU load. When changing the
RETRY_WAIT value, you must consider a number of conditions, including the storage system to be
used, the number of disks to be backed up or restored, the disk sizes, and the difference in data
