Command View SDM Limitations

The Command View SDM Interface

You should only access the Command View SDM array software when it is called
up by Command View NAS. Features available in this software can damage or
delete data from your arrays. Always pay attention to warnings that are displayed
by the software.
Command View SDM array software is launched by Command View NAS for the
following reasons:
The following Command View SDM capabilities 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
Command View NAS. The following Command View features can destroy data on
the system:
240
Status (Failed State) — If there is failure in the storage array hardware,
Command View NAS will not provide any details. Command View SDM
provides details about where within the array the fault has occurred. This
access is for information only.
Diagnostics (Support Tasks) — Diagnostic tools in Command View SDM
are available to assist with isolating problems. To perform diagnostics on the
storage array, Command View NAS will start the Command View SDM web
interface with the "diagnostic" tab selected. This task should only be
performed by an HP service representative.
Firmware Upgrade (Support Tasks) — The Command View SDM
"download" tab is accessed to upgrade storage array firmware. This task
should only be performed by an HP service representative.
Initial System Configuration — During initial system configuration, the
storage array settings should be verified using the Virtual Front Panel (VFP)
using a laptop connection, not the Command View SDM web interface. This
task should only be performed by an HP service representative.
Delete LUN — This feature has the most potential for catastrophic results. If
LUNs are deleted using Command View, all data within the LUN is 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 the storage arrays from the NAS server.
