3. Display a list of the DHCP IP addresses that have been assigned. To do this, type the following SDMC
command:
cat /var/lib/dhcp/db/dhcpd.leases
The output of this command lists all IP addresses that have been assigned by the SDMC's DHCP
server.
4. Make a note of all IP addresses that are listed in the output.
5. Compare the lssysconn and dhcpd.leases lists. If an IP address is displayed in the output for both
the cat /var/lib/dhcp/db/dhcpd.leases and lssysconn -r all commands, the IP address was
assigned by the SDMC DHCP server and the connection is being managed by the SDMC DHCP
server.
6. Remove from the list any address that is displayed in the output of the
cat /var/lib/dhcp/db/
dhcpd.leases
command but not displayed in the output of the
lssysconn -r all
command, and is
not in the list of servers that use static IP addresses.
Note: If an IP address is displayed in the
cat /var/lib/dhcp/db/dhcpd.leases
output and not in the
lssysconn -r all
output, that IP address was assigned by the SDMC DHCP server. However, it is not
a current connection on the SDMC. The DHCP server keeps a history of all IP address assignments in
the event that the connection is re-established. The DHCP server might also have assigned an IP
address if an unknown device on the private network requested a DHCP IP address from the SDMC.
7. If the SDMC is managing servers on both a private and a public network, any connections to the
service processor on the public network (not in the private network address range) must also be
identified and removed from this list. If there are no IP addresses remaining in the list that contains
the
lssyconn -r all
output, the SDMC DHCP server has assigned all of the system IP addresses, and
the network configuration is working correctly.
8.
If there are any IP addresses not removed from the list taken from the
lssysconn -r all
command,
this address was not assigned by the SDMC's DHCP server. These IP address assignments must be
corrected, so that they can be automatically reassigned by the SDMC DHCP server. To add a system
whose IP address is listed in the
dhcpd.leases
list, but not in the
lssysconn
list, type the following
SDMC command:
mksysconn -o auto
If you have followed this procedure and not all of your connections appear to be active, call an
authorized service provider for additional support.
Determining your Systems Director Management Console appliance
code version and release
The level of appliance code on the IBM Systems Director Management Console (SDMC) determines the
available features to upgrading to a new release, including concurrent server firmware maintenance and
enhancements.
To determine how to view the SDMC appliance code version and release, complete the following steps:
1. On the SDMC command line, type
lsconfig -V
.
2. View and record the information that is displayed under the SDMC Code Level heading, including:
the SDMC version, release, service pack, build level, and base versions.
