338 Implementing the IBM Storwize V7000 V6.3
IBM Storwize V7000 must have exclusive access to the LUNs from the external storage
system mapped to it. LUNs cannot be shared between IBM Storwize V7000s or between an
IBM Storwize V7000 and other storage virtualization platforms or between an IBM Storwize
V7000 and hosts. However, different LUNs could be mapped from one external storage
system to an IBM Storwize V7000 and other hosts in the SAN through different storage ports.
Make sure to configure the storage subsystem LUN masking settings to map all LUNs to all
the WWPNs in the IBM Storwize V7000 storage system.
Ensure that you go to the IBM Storwize V7000 Information Center and review the
“Configuring and servicing external storage system” topic ...
