An LDEV can be used for LUSE operations using a path-defined LDEV with the following
considerations:
•
For hosts other than Windows Server 2003, Windows Server 2008, VMware, AIX5.2 and
AIX5.3, an LDEV cannot be used for LUSE operations using a path-defined LDEV.
•
Before performing LUSE operation to an LDEV with a path defined from a Windows Server
2003 or Windows Server 2008 host, ensure that the host mode of the Windows operating
system is 2C (Windows Extension). If the host mode is not 2C, change the host mode to 2C
before performing the LUSE operation.
•
Before performing a LUSE operation on an LDEV with a path defined from a VMware host,
ensure that the host mode of the VMware host is 21 (VMware Extension). If the host mode is
not 21, change the host mode to 21 before performing the LUSE operation.
•
When you combine LDEVs, they must be already formatted and their status must be normal.
•
If you use the VMware host, and the Windows virtual host on the VMware is connected with
the Raw Device Mapping (RDM) method, the host mode 2C Windows Extension must be set.
If the host mode 2C Windows extension is not set, change the host mode to 2C. Before you
change the host mode, back up the LUSE volume. After you change the mode, restore the
LUSE volume.
LUSE provisioning workflow
Expanded LU provisioning workflow includes the following steps.
1. “Opening the LUN Expansion window” (page 67)
2. “Viewing a concatenated parity group” (page 68)
3. “Creating a LUSE volume ” (page 68)
4. “Resetting an unregistered LUSE volume” (page 71)
Opening the LUN Expansion window
The starting place for setting up expanded LU provisioning is the LUN Expansion window.
1.
In the Remote Web Console main window, click Actions> Logical Device > LUN Expansion.
The LUN Expansion window opens, where you can perform LUSE operations.
To exit LUSE, click Close button on the upper right corner of the Remote Web Console main
window, or close the Web browser.
