Logical unit creation and deletion on the EMC CLARiiON

Binding a logical unit (LU) to a RAID group can take a significant amount of time on EMC CLARiiON systems.

Do not add the LU to a storage group until binding is complete. If the LU is mapped to the IBM Spectrum Virtualize™ clustered system during the binding process, the LU might be identified with the wrong capacity. If this occurs, run the following procedure to rediscover the LU with the correct capacity:
  1. Unmap the LU from the system.
  2. Run detectmdisk and wait for the managed disk to be unconfigured.
  3. Wait for any binding activity to complete.
  4. Remap the LU to the IBM Spectrum Virtualize system.
  5. Run detectmdisk.
