SLES 11.3 x86_64 MS node ppc64 SNs
We've upgraded a cluster from 2.7.8 to 2.9.1 and have run into a problem.
When running rnetboot on a lpar it is writing out gateway IP to OF prompt.
This causes issue when we want a client to use a different SN, the OF of
the lpar attempts to bootp to gw (a known issue in the past). Using 2.7.8
either xCAT wasn't exhibiting the same behavior, two SNs in same network
could be used, we did not have errant bootp packets. So, with this upgrade
we have the following situation:
Two SNs on same network, one on .1 and one on .2 the network table has .1
as gw:
lpar that is assigned to .1 SN will bootp and get response fine from .1 and
install normally
lpar that is assigned ot .2 SN will attempt bootp to .1 (even though that
is only the gw assignation on OF prompt, server IP is .2 and OF reflects
that) and eventually fails.
If we flip gw in network table to .2 the reverse of those two outcomes
happens
If we remove gw from the OF command, installs happen to either SN as
directed with no issues (e.g. .1 SN clients bootp and install from .1
SN, .2 clients bootp and install from .2 SN. However removing gw from
network table results is rnetboot failing on no gw and lpar never reaching
bootp attempt. Note that we do not need a gw at all, it is a admin
network, no routing allowed.
