Specifying track sizes used when copying data – HP XP Command View Advanced Edition Software User Manual

Specifiable values
Description
Parameter
0 to 3600
Specify the maximum number of
retries that will be performed to
confirm whether the volume is
ready for resynchronization. You
need to specify this parameter if
you want to check whether the
pair status allows execution of
pairresync -restore
for
restoration. If you specify
0
, Ap-
plication Agent continues to retry
checking until it can check the
pair status.
RESTORE_DELAY_RETRY_TIME
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 “
a retry count and interval for pair status retry checking
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 HP P9500, HP XP24000, HP XP20000, XP12000/XP10000/SVS200, and the
XP1024/XP128 series, 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.
