Configuring iLO 2 62
iLO 2 subsystem name limitations
The iLO 2 subsystem name represents the DNS name of the iLO 2 subsystem. For example,
ilo
instead of
ilo.hp.com
. This name can only be used, if DHCP and DNS are configured properly to connect to the
iLO 2 subsystem name instead of the IP address.
•
Name service limitations—The subsystem name is used as part of the DNS name and WINS name.
However DNS and WINS limitations differ:
o
DNS allows alphanumeric and hyphen. WINS allows alphanumeric, hyphen and underscore.
o
WINS subsystem names are truncated at 15 characters, DNS are not.
If you require underscores, they can be entered in RBSU or using the iLO 2 scripting utility.
NOTE:
Name service limitations also apply to the domain name.
To avoid name space issues:
o
Do not use the underscore character.
o
Limit subsystem names to 15 characters.
o
Verify you can PING iLO by IP address and by DNS/WINS name.
o
Verify NSLOOKUP correctly resolves the iLO network address and that there are no namespace
conflicts.
o
Verify DNS and WINS both correctly resolve the name (if you are using both).
o
Flush the DNS name if you make any name space changes.
iLO 2 Shared Network Port
The iLO 2 Shared Network Port enables you to choose either the system NIC or dedicated iLO 2
Dedicated Management NIC for server management. When you enable the iLO 2 Shared Network Port,
both regular network traffic, and network traffic intended for iLO 2 pass through the system NIC.
iLO 2 provides support for servers that might not have an iLO 2 Dedicated Management NIC. On servers
using the iLO 2 Dedicated Management NIC, the standard hardware configuration provides iLO 2
network connectivity only through the iLO 2 Shared Network Port connection. iLO 2 detects the lack of an
iLO 2 Dedicated Management NIC and automatically defaults to the Shared Network Port. On some of
these servers, an iLO 2 Dedicated Management NIC might be available as a hardware option. If an iLO
2 Dedicated Management NIC is available as a hardware option, iLO 2 defaults to the installed iLO 2
Dedicated Management NIC. On servers using the iLO 2 Dedicated Management NIC, you can enable
shared network port operation through the iLO 2 interface.
The iLO 2 Shared Network Port uses the network port labeled NIC 1 on the rear panel of the server. NIC
numbering in the operating system can be different from system numbering. The iLO 2 Shared Network
Port does not incur an iLO 2 performance penalty. Peak iLO 2 traffic is less than 2 MB (on a NIC capable
of 1000-Mb speeds), and average iLO 2 traffic is infrequent and low.
The Shared Network Port is not available on HP ProLiant ML310 G3, ML310 G4, BL20p G4, and all c-
Class blade servers.
iLO 2 Shared Management Port features and restrictions
iLO 2 Shared Network Port and the iLO 2 Dedicated Management NIC port are used for iLO 2 server
management. You can only use the iLO 2 Shared Network Port and the iLO 2 Dedicated Management
