#2497 no dhcp-server error in sles11sp1 fresh install

[BaiYuan]

When I use zyper install xCAT, xCAT can not find dhcp-server;There is no dhcp-server packages in xcat-dep; And the doc does not mention to install the dhcp-server;So I hit the error as follows,I think the doc should mention dhcp-server should be installed manually on sles11 sp1 or it should be contained in xcat-dep;

Installation of xCAT-2.6.10-snap201112052142 failed:
(with --nodeps --force) Error: Subprocess failed. Error: RPM failed:
!! On SuSE, the dhcp-server package should be installed before installing xCAT !!
error: %pre(xCAT-2.6.10-snap201112052142.ppc64) scriptlet failed, exit status 255
error: install: %pre scriptlet failed (2), skipping xCAT-2.6.10-snap201112052142
Abort, retry, ignore? [a/r/i] (a):
Problem occured during or after installation or removal of packages:
Installation aborted by user
Please see the above error message for a hint.

The work around is that installing dhcp-server manually before installing xCAT;

I think the error message is clear enough, you should install dhcp-server before installing xCAT, we already documented this in hte pLinux cookbook. We can not specify the dhcp-server as the prerequisite of xCAT, because the dhcp package on RHEL and SLES has different names.

[SLES] Check the installation of dhcp-server

On the SLES management node, the dhcp-server rpm may not have been automatically installed. Use following command to check whether it has been installed:

rpm -qa | grep -E "^dhcp-server"

If it is not installed, installed it manually:

zypper install dhcp-server
