General Functionality Issues and Limitations

Caution – For dynamic reconfiguration (DR) and hot-plug issues, see
Issues and Workarounds" on page
You cannot use the following user account names, as they are reserved for system
■
use: adm, admin, apache, bin, daemon, default, ldap, nobody, ntp,
operator, proxyuser, root, rpc, rpcuser, and sshd.
Do not use the Service Processor (SP) as the Network Time Protocol (NTP) server.
■
Using an independent NTP server provides optimal reliability in maintaining
consistent time on the SP and the domains. For more information about NTP, see
the Sun BluePrints
Clocks:
When you use the external power control interface of the external power
■
controller, the following notification signals are not supported:
■
■
When you import XCP or update the firmware using the XSCF you might see
■
Web session ID errors displayed on the web browser. When you specify the
timeout period as over 30 minutes in the Autologout setting Internal Server
Errors might be displayed. To reconnect to the XSCF Web, close the current
browser and open the new browser.
For this XCP release, the XSCF browser user interface (XSCF Web) does not
■
support the External I/O Expansion Unit Manager feature.
Disable pop-up blocking and remove any plug-ins such as the search tool
■
installed with the browser when you use the XSCF Web.
XSCF-LAN is compliant with auto-negotiation. Set the network device which
■
connects with XSCF-LAN to the auto-negotiation mode. Otherwise when you
connect the XSCF-LAN and the network device (fixed to the full-duplex mode,
according to the IEEE 802.3 rule) the XSCF-LAN communicates in half-duplex
mode and network communication speed might slow down or communication
errors may occur.
Due to DR and ZFS file system interoperability issues, M8000/M9000 servers are
■
shipped pre-installed using the UFS file system. For more information, refer to the
description and workaround for CR 6522017 in
For information about I/O options and storage, such as the number of cards
■
supported in a domain, see the Sun Cross Platform IO Support page:
http://wikis.sun.com/display/PlatformIoSupport/Home/
Do not use the CD-RW/DVD-RW drive unit and the TAPE drive unit at the same
■
time.
