HP StorageWorks XP24000 Continuous Access Journal Software User and Reference Guide, v01 (T5278-96001, June 2007)
data volumes are automatically assigned according to the LUN. For example, if you select three
primary data volumes and select LUN01 as the S-VOL for the first primary data volume, the
secondary data volumes for the two other primary data volumes will be LUN02 and LUN03.
Note:
When creating more tha n one pair at a time, make sure that the S-VOLs to be assigned
automatically are available. If an S-VOL is not available, you will have to select the S-VOL
individually.
Note:
You can specify the port number as two characters. For instance, you can abbreviate CL1-A
to
1A. You can also enter the port number in both lowercase and uppercase characters.
• Select Other S-VOL(s): Specify how Continuous Access Journal automatically will assign secondary
data volumes if two or more primary data volumes are selected in the Pair Operation window.
• Increm ent : Continuous Access Journal increments LUNs of the resulting secondar y data
volumes one by one. For example, if the LUNs of the three primary data volumes are 001,
002,and 003, the LUNs of the resulting secondary data volumes will be 011, 012, and 013
if
you select the LUN 011 with the S-VOL drop-down list.
• Input Next: Continuous Access Journal users can specify a LUN for each primary data volume.
For example, if two primary data volumes are selected, the Continuous Access Journal user
must
select Input Next, specify the secondary data volume for the first primary data volume
with S-VOL, and then click Set. Next, theusermustspecify thesecondary datavolumefor the
second primary data volume with S-VOL, and then click Set.
• Relative to P-VOL: Continuous Access Journal calculates the difference between LUNs of two
adjacent primary data volumes, and then determines LUNs of secondary data volumes.
For example, if the LUNs of the three primary data volumes are 001, 005,and 006,the LUNs
of the
resulting secondary data volumes will be 002, 006, and 007 if you select the LUN
002 with the S-VOL drop-down list.
Note
: If you select and right-click m ore than one volume in the Preview list a nd then select Modify,
the
Paircreate window appears and the Select Other S-VOL(s) drop-down list displays No Change.
To change the setting with this drop-down list, select another item from the drop-down list.
• Mirror: Assigns a master journal g roup to the p rimary data volume, assigns a restore journal
grouptothe secondary datavolume, andalsoassigns amirror IDtothe volume pair.
• M-JNL: Assigns a master journal group to the primary data volume.
Note
: M-JNL d oes not display journal group numbers used by U niversal Replicator for
Mainframe.
• Mirror ID: Assigns a mirror ID to the volume pair.
• R-JNL: Assigns a restore journal group to the secondary data volume.
Note
: R-JNL does not display journal group numbers used by Universal Replicator for
Mainframe.
• CT Group: Allows you to specify a consistency group.
Note:
This option cannot be changed after a pair has been created.
• DKC: Allows you to select the serial num b er with the number of L DKC and the c ontroller ID
with the model nam e of the seco ndary storage system. This option also allows you to specify
the
path type (that is, channel type).
Note:
The secondary storage system must be the same for all pairs being created during one
operation.
• Initial C opy: Allows you to specify whether to start the initial copy op eration after the volume
pair is created. The default is Entire.
• Entire: The initial copy operation will start after the volume pair is created. When the
initial copy operation executes, all data on the primary data volume will be copied to the
secondary data volume.
• None: The initial copy operation will not start after the volume pair is created. The primary
storage system starts copying of update d ata as needed.
Caution:
Theusermustensurethatthe primarydatavolumeand secondarydatavolume are
already identical when using None.
• Priority: Allows you to specify priority (scheduling order) of the initial copy operations (1-256).
The default setting is 3 2.
Note:
If the tim e out error occurs during the Paircreate o peration, the co py operation m ay not b e
executed correctly in the order that you have set with the Priority parameter. Thetimeout error
