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 “

Specifying

a retry count and interval for pair status retry checking

” on page 118.

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.
