Table 28 Pair Operation Window Details (continued)

Description

Item

Sync: If the volume in the local storage system is a
primary data volume, this column shows progress of an
initial copy operation. If the volume in the local storage
system is a secondary data volume, this column shows
information in the following ways:

◦ If the volume pair is not split, this column shows

nothing.

◦ If the volume pair is split and therefore is in PSUS or

PSUE status, this column usually shows
synchronization rate (that is, concordance rate)
between the secondary data volume before it
became split and the secondary data volume after
it became split. For example, the synchronization
rate (that is, concordance rate) is 100% if the
contents of the secondary data volume are the same
before and after the volume pair became split.

Caution: If a failure in the initial copy operation causes
the volume pair to be split, this column displays nothing.
If a failure occurs in the initial copy operation, the
Detailed Information window (

“Detailed Information

Window” (page 185)

) displays the phrase Initial

copy failed

.

In the following cases, this column will be blank:

◦ When the volume in the local storage system is

neither a primary data volume nor a secondary data
volume.

◦ When the status of the volume pair is HOLD,

HOLDING, or HLDE.

CLPR: The number and the name of the CLPR where the
data volume belongs.

Pair Copy Time: The time taken for the copy operation
(from the start of the operation to the end). The time that
is shown in Pair Copy Time differs from the time that is
shown in Copy Time on the History window.

To create a pair:
1. MCU receives a request to create a pair.
2. MCU receives a request to start the paircreate

operation.

3. The paircreate operation is started according to the

conditions of initial copy priority and maximum initial
copy activities.

Pair Copy Time shows the amount of time needed from
step c to the completion of the paircreate operation (for
example, the progress of the paircreate operation
reaches 100%). Copy Time on the History window
shows the amount of time needed from step a to the
completion of the paircreate operation.

The size of used volumes, and also indicates the licensed
capacity. For example, if 12.34 (15.0) (TB) appears, the

Used Volume

licensed capacity for XP Continuous Access Journal is 15.0
terabytes, and 12.34 terabytes of volumes are used. If the
licensed capacity is unlimited, the size of used volume does
not appear.
