214 Command View SDM Limitations
(VFP) using a laptop connection, not the Command View SDM interface.
This task should only be performed by an HP service representative.
The following capabilities of the Command View SDM interface are
potentially dangerous to the data in the NAS 8000 configuration and should
never be used.
LUN Management — All LUN management tasks should be performed using
the Command View NAS interface. The following features of the Command
View SDM interface can destroy data on the system:
■ Delete LUN — This feature has the most potential for catastrophic results.
If LUNs are deleted using Command View SDM, all data within the LUN
will be lost.
■ Create Business Copy (Snapshot) — Business copies (hardware
snapshots) are not supported by the NAS 8000 solution. If a business
copy snapshot is created, the storage capacity allocated to the snapshot
will not be available for use.
■ LUN Permissions — If device-based LUN security is enabled, it will not be
possible to access to the storage arrays from the NAS server.
Configuration — These features are set during initial system setup. Once set,
they should not be changed.
■ Host Port Behavior — This is set to the correct value during initial
configuration and should not be changed. It this is changed, the storage
arrays will not communicate with the NAS server. This task should be
performed by an HP service representative.
■ Host Port ID — This is the Fibre Channel bus address. It is set to be a valid
address that does not conflict with other devices on the bus during initial
installation. Changing this value has unpredictable results.
■ Data Resiliency — Changing this value could result in performance
changes and jeopardizes the integrity of the data stored on the device in
the event of a component of power failure.
■ Automatic include/format/spare — These settings control what happens
how new disk drives are handles when they inserted into storage array.
Changing these settings may result in new storage not being visible to the
NAS server.
■ Auto Rebuild — This setting controls what happens when a drive fails (if
an auto rebuild of the RAID set occurs). Changing the value will require
manual intervention to rebuild the RAID after a drive failure.
