Select Secondary Volumes window

This window is the third window of the Create SI Pairs wizard. Use this window to select the LDEVs that are the S-VOL and to remove unwanted pairs or LDEVs.

This window includes the following tables:

Available LDEVs table

Selected LDEVs table

The following table shows the items in this window.


Item	Description
Capacity list	Click to select the capacity by which to filter the available LDEVs.
The remaining number you have to select	This item refers to the P-VOLs in the Selected Pairs table that do not have an assigned S-VOL.
Exclude Paired Volumes	SI only. Select to hide volumes already in a pair. Values: Selected: Paired volumes are not shown in the list. Cleared: Paired volumes are shown in the list. Default: Selected
Port ID list	Filters LDEVs in the Available LDEVs table according to the port ID. Default: CL1-A
Host Group Name list	Filters LDEVs in the Available LDEVs table according to the host group name. Default: Any
iSCSI Target Alias	Filters LDEVs in the Available LDEVs table according to iSCSI target alias. Default: Any
Snapshot Group	HTI only. Select whether you want to create a new snapshot group or use an existing snapshot group. Values: Create new snapshot group: The new snapshot group name is entered. Use defined snapshot group: An existing snapshot group is selected. If you have not assigned the pair to a snapshot group, this item is blank.
Set button	Click to move an LDEV that you have selected in the Available LDEVs table to the Selected Pairs table. You can also click to configure a pair you have selected in the Available LDEVs table and a pair you have selected in the Selected Pairs table.
Clear button	Click to return the selected S-VOL from the Selected Pairs table back to the Available LDEVs table.
Sort Pairs button	SI only. Click to sort the Selected Pairs table according to the following: Arrange in Mirror Unit: Data is shown according to mirror units. Arrange in Topology: Data is shown according to its topology. For example, L1 or L2 pairs.

Available LDEVs table

The following table shows the items in this table of the Select Secondary Volumes window of the Create SI Pairs wizard.


Item	Description
LDEV ID	The LDEV's identifier.
LDEV Name	The LDEV's name.
Port ID	The port name of the LDEV's LUN path.
Host Group Name / iSCSI Target Alias	The host group name (and ID) and iSCSI target alias (and ID) of the LDEV's LUN path.
iSCSI Target Name	iSCSI target name.
LUN ID	LUN identifier of the LDEV's LUN path.
Capacity	The LDEV's capacity.
Provisioning Type	SI only. The LDEV's provisioning type. Values: Basic: Internal volume DP: DP-VOL External: External volume Snapshot: HTI volume
CLPR	The LDEV's CLPR number.
Number of Secondary Volumes	SI only. The number of S-VOLs that the selected P-VOL has been assigned so far.
Detail button	Click to open the LDEV Properties window, which contains additional information for the selected LDEV.

Selected Pairs table

The following table shows the items in this table of the Select Secondary Volumes window of the Create SI Pairs wizard.


Item	Description
Primary Volume	The P-VOL information. Values: LDEV ID: The P-VOL's LDEV identifier. LDEV Name: The P-VOL's LDEV name. A hyphen (-) displays if no LDEV is assigned. Port ID: The port name of the P-VOL LDEV's LUN path. Host Group Name / iSCSI Target Alias: Host group name (and ID) and iSCSI target alias (and ID) of the P-VOL LDEV's LUN path. iSCSI Target Name: The P-VOL's iSCSI target name. LUN ID: The LUN identifier of the P-VOL LDEV's LUN path. Capacity: The P-VOL's volume capacity.
Secondary Volume	The S-VOL information. Values: LDEV ID: The S-VOL's LDEV identifier. This item is blank if no LDEV is assigned. LDEV Name: The S-VOL's LDEV name. A hyphen (-) displays if no LDEV is assigned. Port ID: Port name of the S-VOL LDEV's LUN path. Host Group Name / iSCSI Target Alias: Host group name (and ID) and iSCSI target alias (and ID) of the S-VOL LDEV's LUN path. iSCSI Target Name: The S-VOL's iSCSI target name. LUN ID: LUN identifier of the S-VOL LDEV's LUN path. Capacity: The S-VOL's volume capacity.
Copy Type	The types of pairs. Values: SI-L1: SI L1 SI-L2: SI L2
Mirror Unit	SI only. The mirror unit number.

Split Type	SI only. The split type. Values: Non Split: The pair is not split. Quick Split: The pair is split and then the data is copied so that the S-VOL is immediately available for read and write I/O. Any remaining differential data is copied to the S-VOL in the background. Steady Split: Differential data is copied, and then the pair is split.
Copy Pace	SI only. The system option that determines the rate at which you want the VSP G200, G400, G600 storage system to copy data. Values: Slower: Improved host server I/O performance but slower processing speed. Medium: Average processing speed and host server I/O performance. Faster: Faster processing speed but slower host server I/O performance.
Change Options button	SI only. Click to open the Change Options dialog box. Options set in the Change Options dialog box will be applied to all the pairs newly created.
Edit Mirror Units button	SI only. Click to open the Edit Mirror Units dialog box. Use this dialog box to change the S-VOL's L1 and L2 mirror unit numbers, and thereby, pair topology. For more information about changing the MU number and pair topology, see and Creating L1 and L2 pairs with different topologies the topic on pair creation: click Show All Contents and then select In-System Replication to navigate to the desired software and information.
Remove button	Click to remove the unwanted pairs or LDEV from the Selected Pairs table. Note: For SI, you cannot remove L1 pairs if the pairs have an L2 pair.
