HP StorageWorks XP24000 Continuous Access Journal Software User and Reference Guide, v01 (T5278-96001, June 2007)

c d e f
c Port
d Group number of the host group
e LUN (logical unit number).
f Logical volume ID. Indicates the number of "LDKC : CU : LDEV".
Note : If a volume is an external volume, the # symbol appears after the LD EV number. For
detailed information about external volumes, see the HP StorageWorks XP24000 External Storage
Software User’s Guide.
Note: If a volume is a volume of an HP XP12000 Disk Array, 00 is displayed as the LDKC number.
Figure 40 Information in the Paired VOL Column in the Pair Operation Window
This column is blank if the volume in the local storage system is neither a primary d ata volume
nor a
secondary data volume.
• 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 d ata volume
nor a
secondary data volume.
• CTG: Indicates the consistency group number.
This column is blank if the volume in the local storage system is neither a primary d ata volume
nor a
secondary data volume.
• Err Lv.: Indicates the range of the pair split for an error.
If an error occurs with this pair, all the pairs in the mirror where this pair belongs will
Group
be split.
LU
If an
error occurs with this pair, only this pair will be split.
• Sync.: If the volume in the local storage system is a primary data volume, this column displays
the
progress of an initial copy op eration.
If the
volume in the local storage system is a secondary data volume, this colu m n d isplays
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 PSUS or PSUE status, this column usually
displays the 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 1 0 0 percent if the contents
of the
secondary data volume is 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 o p eration, the Detailed
Information window (Figure 63 on page 132) displays thephraseInitial copy failed.
In the following cases, this c olumn will be blank.
• When the volume in the local storage system is n either a primary data volume nor a
secondary data volume.
• CLPR: Indicates the number and the name of the CLPR to which the data volume belongs.
• Pair Copy Time: The time taken for the c opy operation (from the start of the operation to
the
end).
Note : The time that is shown in Pair Copy Time differs from the tim e that is shown in Copy
Time on the History window .
To create a pair:
1. The MCU receives a request to create a pair.
2. The MCU receives a request to start the paircreate operation.
