IBM® DS5000, IBM DS4000®, and IBM DS3000 series storage systems provide functions that can be used with the Lenovo Storage V7000.
Diagnostics are automatically recovered by the Lenovo Storage V7000system. After the controller run diagnostics option is used, check your managed disks (MDisks) to ensure that they have not been set to degraded mode.
The controller disable data transfer option is not supported when a Lenovo Storage V7000 is attached to IBM DS5000, IBM DS4000, or IBM DS3000 systems.
Do not set an array offline because you can lose access to the storage pool.
The array increase capacity option is supported, but the new capacity is not usable until the MDisk is removed from the storage pool and re-added 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; however, these options might not take effect until a discovery is started on the Lenovo Storage V7000clustered 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 might have been added to the system and to rebalance MDisk access across the available storage system ports.
You must only use the controller reset option if you are directed to do so by IBM Service and the alternate controller is functional and available to the SAN. The Lenovo Storage V7000 reset is automatically recovered by the Lenovo Storage V7000system.
Check your MDisks to ensure that they have not been set to the degraded state during the controller reset process. You can issue the includemdisk CLI command to repair degraded MDisks.
