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

Specifiable valuesDescriptionParameter
0 to 360000
Specify the interval between re-
tries that will be performed to
confirm whether the volume is
ready for resynchronization. This
value must be specified in units
of 10 milliseconds. You need to
specify this parameter if you want
to check whether the pair status
allows execution of pairresync
-restore for restoration.
RESTORE_DELAY_RETRY_WAIT
For notes on specifying the above values and calculation methods of setting values, see “Specifying
a retry count and interval for pair status retry checking” on page 121.
Specifying track sizes used when copying data
You can change the track size used for copying data that is to be resynchronized at backup or
restoration. For example, you may want to change the track size for copying data in the following
cases:
• When the priority of I/O for the primary volume is higher than the priority of data copying:
Assign a smaller value to the COPY_SIZE parameter.
• When the priority of data copying is higher, in order to finish copying faster:
Assign a larger value to the COPY_SIZE parameter.
If you are using a XP1024/XP128 series, XP12000/XP10000/SVS200, HP XP24000, HP XP20000,
or Virtual Storage Platform storage system, do not specify 15. If you specify 15, system operations
might be affected because the highest priority will be placed on data-copy processing, and then input
to the primary volume will stop.
For details about the values that can be specified as the track size, see the RAID Manager
documentation.
Table 36 Parameter in the RAID Manager-linkage definition file (DEFAULT.dat) (to specify the track
size used when copying data)
Specifiable values
(default)
DescriptionParameter
1 to 15
(RAID Manager's
default)
Specifies the track size (the number of volume-type sec-
tors per track) that can be copied in a batch for one
copy unit when copying is performed from the primary
to secondary volume or from the secondary to primary
volume.
COPY_SIZE
In addition to specifying the COPY_SIZE parameter, you can also specify the track size by using
other methods. The methods are listed below. When multiple methods are used to specify the track
size, the valid method is selected in the order shown:
1. The -copy_size option (used only by the EX_DRM_RESYNC command)
2. The DRM_COPY_SIZE environment variable
3. The COPY_SIZE parameter
4. The default value for RAID Manager
