HP StorageWorks XP Remote Web Console Software - Manual (Page 139)

NOTE: If a volume is an external volume, the symbol "#" appears after the LDEV number.
For detailed information about external volumes, see the XP External Storage Software
user’s guide.
◦ Pair JNLG: Indicates the journal group number for the remote storage system.
This column is blank if the volume in the local storage system is neither a primary data
volume nor a secondary data volume.
◦ Err Lv.: Indicates the range of pair split on error.
If an error occurs with this pair, all the pairs in the mirror where this pair belongs will be split. Group
If an error occurs with this pair, only this pair will be split. Volume
◦ Sync.: If the volume in the local storage system is a primary data volume, this column
displays progress of an initial copy operation.
If the volume in the local storage system is a secondary data volume, this column displays
information in the following ways:
– If the volume pair is not split, this column displays nothing.
– If the volume pair is split and therefore is in Suspend status, this column usually
displays 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 percent 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 (
“Pair Status Panel” (page 147) ) 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 or Hlde.
◦ CLPR: Indicates 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).
NOTE: 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 creating pair operation.
3. The creating pair operation is started according to the conditions of initial copy
priority and maximum initial copy activities.
Pair Copy Time on the Detailed Information dialog box shows the amount of time that has
been needed from step 3 to the completion of the creating pair operation (that is, the
progress of the creating pair operation reaches 100%). Copy Time on the History window
