Logical unit creation and deletion on the IBM ESS

Certain IBM® Enterprise Storage Server® (ESS) types are supported for use with the SAN Volume Controller.

Before you delete or unmap a logical unit (LU) from the SAN Volume Controller, remove the LU from the managed disk (MDisk) group. The following is supported:
  • LU size of 1 GB to 2 TB.
  • RAID 5 and RAID 10 LUs.
  • LUs can be added dynamically.
Attention: When adding additional SAN Volume Controller ports to an existing LU, you must select the Use same ID/LUN in source and target check box. Failure to select the Use same ID/LUN in source and target checkbox can cause loss in redundancy or a loss of data. If this checkbox is not available, the option is not required. The detect MDisks task in the SAN Volume Controller Console or the svctask detectmdisk command-line interface (CLI) command must be run for the SAN Volume Controller to detect the new disks.
