Launching LUN Expansion
To launch LUN Expansion:
1.
In the Remote Web Console main window, click Go, Volume Manager, and then LUN Expansion
on the menu bar.
The LUSE window opens. This window enables you to perform LUSE operations.
NOTE:
To exit LUSE, click the Logout button
in the upper right corner of the Remote
Web Console main window, or end the Web browser.
If you are going to implement any changes for LUSE, you must have modify permission for
LUSE.
2.
You can view the current LUSE configuration on the LUSE window (
).
•
The LDEV Information tree displays an outline view of the CU numbers in a hierarchical
structure.
•
The LDEV Detail table displays detailed information for all open-system LDEVs in the
selected CU.
Viewing Concatenated Parity Groups
In the storage system, data can be written to an LDEV that extends over concatenated parity groups.
Concatenation of parity groups enables faster access to data.
To view a concatenated parity group:
1.
Make sure that Remote Web Console is in Modify mode.
For detailed information about Modify mode, see the HP StorageWorks XP24000/XP20000
Remote Web Console User Guide.
2.
Select a CU number from the LDEV Information tree. The LDEV Detail table displays all LDEVs
in the selected CU.
3.
In the LDEV Detail table, select and right-click the free LDEVs that you want to use to form the
LUSE volume. If parity groups are concatenated, the Concatenation List menu displays. The
Concatenation List command does not display if the selected LDEV does not extend over
concatenated parity groups.
