RE: "pump" times out -- extend a few seconds more?



We build HP DL 380/385/580/585 servers every day while connected to
Cisco switches that we don't have any access to.  Are you using RHEL 3
or 4?  If 4, do you have spare NIC's in the box? RHEL 4 enumerates the
bus backwards from RHEL 3, so if you have a NIC, it's going to be eth0
instead of the onboard...

I am experiencing a similar problem; however, my situation is slightly
different.

I have HP DL385's connected to a 48 port 10/100 module in a Cisco 6509
(with Sup 2 routing module).  I'm using the virtual CDROM via the HP ILO
(Integrated Lights Out) interface to perform the initial boot.  I mount
a customized version of RHEL3U5 CD1.  My kickstart file is specified as
an url.  The system boots and Anaconda starts, but before the link
negotiation can complete Anaconda times-out and I am dumped into an
interactive install.

A couple of data points:

1) The HP DL385 on-board NICs are manufactured by Broadcom.  I've read
about a known bug with link negotiation between the Broadcom NICs and
Cisco 48-port line cards.  The link negotiation works, it just takes a
"longer" time than with any other kind of NIC.

2) Setting the switch port NIC to enable "spanning-tree portfast" does
shorten the link negotiation time, but not enough to get around my
problem.

Work Arounds:

1) I will prebuild the kickstart configs and place them on my customized
RHEL3U5 CD.  I've been unsuccessful at reading the kickstart config from
the CDROM.  The driver supporting the ILO virtual cdrom does not name
the cdrom device as "cdrom".  Still reading up on this.

That's it so far,
-Bill
