The smaller the retry interval value ( RESYNC_RETRY_WAIT , SPLIT_RETRY_WAIT , RE-
STORE_RETRY_WAIT , BUSY_RETRY_WAIT , or RESTORE_DELAY_RETRY_WAIT ), the larger
the CPU load. Refer to Table 26 and specify a value appropriate to the storage system to be
used.
Specifying a retry count and interval for RAID Manager command busy retry
checking
If a RAID Manager command returns a busy status, Application Agent tries to execute the command
again. If you want to change the RAID Manager command retry count and interval, add the following
parameters:
Table 28 Parameters in the RAID Manager-linkage definition file (DEFAULT.dat) (to specify a retry
count and a retry interval for RAID Manager command busy status retries checking)
Specifiable values
(default)
Description Parameter
1 to 3600
(3)
Specify the maximum RAID Manager command busy
status checking retry count.
Specify this parameter to check the pair status if the
RAID Manager command returns a busy status.
BUSY_RETRY_TIME
1 to 360000
(100)
Specifies the retry interval for checking the pair status
when the RAID Manager command returns a busy status.
You can specify a value in units of 10 milliseconds.
Specify this parameter to check the pair status if the
RAID Manager command returns a busy status.
When adding this parameter, you should determine the
value after considering how frequently a RAID Manager
command busy condition (such as server overload or
traffic concentration on the communication path) will be
encountered and how much time will be required to
eliminate this condition. Take adequate care because
decreasing the retry interval may further increase the
RAID Manager load.
BUSY_RETRY_WAIT
Specifying a retry count and interval appropriate to operation style
In operations such as backing up to a remote site, if you want to specify a different retry time (for
retrying to confirm the pair status, which will be used in backup, restore, or resynchronization) at
each command execution, you can use the copy parameter definition file. Set the retry time appropriate
to the operation by specifying a copy parameter definition file name as an argument when executing
the command.
When a retry time for pair status confirmation is specified in a copy parameter definition file, the
value is given priority over the one in the RAID Manager-linkage definition file (
DEFAULT.dat ). The
value in the RAID Manager-linkage definition file (
DEFAULT.dat
) is used when the value is not
specified in the copy parameter definition file, or the value in the file is incorrect.
Create copy parameter definition files, using any valid file name, in the following location:
Application-Agent-installation-directory \DRM\conf\raid\ arbitrary-file-name
The coding rules for the copy parameter definition file is explained below:
• Parameter names are case sensitive.
