Remember these guidelines and processes when you use NetApp E-Series as an external storage system tothe system.
Dynamic disk pools are supported.
Thin-provisioned LUNs are supported. Care must be taken for the LUNs not to become over-allocated; if that occurs, the system takes the MDisk and its storage pool offline until this allocation is corrected.
Diagnostics are automatically recovered bythe system. After the controller run diagnostics option is used, check to make sure your managed disks (MDisks) are not set to degraded mode.
The controller disable data transfer option is not supported when the system is attached to NetApp E-Series systems.
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.
You can redistribute logical drives or change ownership of the preferred path. These options, however, might not take effect until a discovery is started onthe 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.
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 system reset is automatically recovered.
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.
