HP Virtual Connect Manager Command Line Interface for c-Class BladeSystem Version 4.01 User Guide

Introduction 12
Each version of VC is tested and supported with one or more SPPs. For a list of supported SPPs that must be
installed, see the VC release notes.
Using multiple enclosures
Multiple enclosure support enables up to four c7000 enclosures to be managed within a single Virtual
Connect domain for a total of 128 servers, if double-dense support is enabled while using the Domain Setup
Wizard. There are 16 half-height or 8 full-height server bays in a c7000 enclosure. A combination of
full-height and half-height servers can be used in the same enclosure.
Multiple enclosure domains are not supported on c3000 enclosures. The VC-Enet or FlexFabric modules use
stacking cables between enclosures so that network traffic can be routed from any server Ethernet port to any
uplink within the VC domain. Since FC does not support stacking, the VC-FC or FlexFabric module FC uplinks
on the same bay of all enclosures must be connected to the same FC switch to enable profile mobility.
The management interfaces for all enclosure Onboard Administrators and VC modules within the same VC
domain must be on the same lightly loaded subnet and highly reliable network. Overloads or loss of
connectivity can disable configuration attempts until the connectivity is re-established and synchronized with
the domain. The Onboard Administrator IP addresses used must be configured to be static. The Onboard
Administrator user credential for all enclosures must be consistent to enable VCSU firmware updates for VC
modules in the remote enclosures. All FC-capable modules in the same horizontally adjacent bay pair (bays
1-2, 3-4, and so on) must be of the same type and position in all enclosures.
Multi-enclosure double-dense domains require similar and compatible VC-FC modules in bays 5, 6, 7, and
8 in all enclosures if FC connectivity is required. If a multi-enclosure double-dense configuration contains
incompatible VC-FC modules in bays 5, 6, 7, or 8 in the local or remote enclosures, some or all of the
compatible VC-FC modules in the remote enclosures might be designated INCOMPATIBLE after import.
Command line overview
The VCM Command Line Interface can be used as an alternative method for administering the VCM. Using
the CLI can be useful in the following scenarios:
• You can develop tools that utilize VCM functions for data collection and for executing provisioning and
configuration tasks.
• When no browser is available or you prefer to use a command line interface, you can access
management data and perform configuration tasks.
• You can batch commands using script files. These script files can be run manually or scheduled to run
automatically.
Command line syntax
CLI input is case-insensitive, except when otherwise noted. The general CLI syntax format is as follows:
<subcommand> <managed element> <parameters> [<options>] [<properties>]
Item Description
subcommand
Operation performed on a managed element
managed element
Target management entity
