Checking an external LU’s status (LDEV Information)
After mapping an external LU as a local array internal LDEV, the external LU is available for operations in
External Storage XP, Flex Copy, and other HP StorageWorks products that support mapped external LUs.
Use the LDEV Information window ( Figure 55 ) to check the status of mapped external LUs.
When a failure occurs in the path between the local array and external array, and also in the specified
alternate paths, the local array recognizes the external LU as blocked (Blockade). To restore the blocked
volume, execute the Restore command on the LDEV Information window.
Obtaining information about external LUs
The LDEV Information window displays information about external arrays and external LUs mapped as
internal LDEVs. To display this window, select the external LU group number in the Device list, right-click
the LU you want to display in the Device list, and select LDEV Information.
