Functions for NetApp E-Series storage systems
Remember these guidelines and processes when you use NetApp E-Series as an external storage system to Storwize® V3700.
Copy functions for NetApp E-Series
The NetApp E-Series replication and snapshot features are not supported under Storwize V3700.Dynamic pools
Dynamic disk pools are supported.
Thin provisioning
Thin-provisioned LUNs are supported. Care must be taken for the LUNs not to become over-allocated or Storwize V3700 takes the MDisk and its storage pool offline until this allocation is corrected.
Controller run diagnostics
Diagnostics are automatically recovered by Storwize V3700. After the controller run diagnostics option is used, check to make sure your managed disks (MDisks) are not set to degraded mode.
Controller disable data transfer
The controller disable data transfer option is not supported when Storwize V3700 is attached to NetApp E-Series systems.
Setting an array offline
Do not set an array offline because you can lose access to the storage pool.Array increase capacity
The array increase capacity option is supported, but the new capacity is not usable until the MDisk is removed from the storage pool and readded to the storage pool. You might have to migrate data to increase the capacity.
Redistributing logical drives or change ownership of the preferred path
You can redistribute logical drives or change ownership of the preferred path. These options, however, might not take effect until a discovery is started on the Storwize V3700 system. You can use the detectmdisk command-line interface (CLI) command to restart a system discovery process. The discovery process rescans the Fibre Channel network to discover any new MDisks that were added to the system and to rebalance MDisk access across the available storage system ports.
Controller reset
You must use the controller reset option only if you are directed to do so by a service representative and the alternate controller is functional and available to the SAN. The Storwize V3700 reset is automatically recovered by the Storwize V3700 system.
Check your MDisks to ensure that they are not set to the degraded state during the controller reset process. You can issue the includemdisk CLI command to repair degraded MDisks.
