HP Virtual Connect 4Gb Fibre Channel Module for c-Class BladeSystem - Manual (Page 5)

Introduction 5
• No firewalls can exist between the client system and the remote enclosure Onboard Administrator. If
a firewall exists, and it is blocking ports, then the utility cannot open a connection with the remote
modules to perform the update.
• Onboard Administrator firmware v1.30 or higher is required for correct VCSU operation.
• Only one instance of the VC Support Utility accessing a single enclosure can be run on a single
client at one time.
• During firmware update operations, the modules are unavailable for use. Any attempt to reset or
remove the modules during the update process could result in a corrupted firmware image. In
addition, do not reset the Onboard Administrator of the target enclosure or update its firmware while
VC modules are being updated. Doing so can interfere with the firmware update process and cause
it to fail. During the firmware update process, connectivity through the modules, which might be
hosted to servers in the enclosure, can be interrupted temporarily.
• During a firmware update session, only use a single client to update modules in a specific remote
enclosure. Using multiple clients to interface remotely with the same enclosure can interrupt the
firmware update process and prevent it from completing successfully.
• If the firmware update client is interrupted or loses network connectivity during the update, reset the
affected module and restart the firmware update process.
Restrictions and limitations
• This version of VCSU supports c3000 and c7000 enclosures.
• The utility does not update modules that are not physically present, are powered off, or are non-
functional. A status message indicates if any modules are in these states.
• The utility does not update unknown or unsupported module types, including pass-thru Ethernet and
FC modules.
• HTTP and HTTPS downloads are restricted to non-authenticated websites.
• FTP downloads are restricted to non-SSL/TLS, Passive Transfer Mode FTP sites.
• Any IP addresses that are not accessible timeout within 20 seconds. Any IP addresses that have an
active SSL enabled web server, but not an OA, fail immediately.
• Only IPv4 addresses are supported in this release.
Command line syntax
CLI input is case-insensitive except when otherwise noted. The general CLI syntax is as follows:
vcsu -a <command>
Parameters are extensions that provide extra information required for the execution of a particular
command. Whether or not a parameter is required depends on the specific action being executed.
For example, the version command includes parameters for IP address, username, password, and bay
location. The syntax is as follows:
vcsu -a version -i <IP> -u <USER> -p <PWD> [-b <BAY>]
NOTE: When entering a username from a Linux command shell with the domain\username
format, use quotation marks around the username ("domain\username") so it is not
expanded by the Linux shell.
