We are in the process of bringing up a Tivoli Storage Manager [TSM] server
using zLinux [SLES11] under zVM [6.2]. We are going to use the IBM7650G with
XIV back end storage to provide Virtual Tape. The idea is to backup intel
servers directly to tape then replicate to remote DR site.
We have
That case (of wanting to load-balance traffic between two or more network
interfaces which can all access the same destinations) could be handled by
network interface bonding - but then you'd have only one IP address and
subnet for the entire bond. Different issue.
I think Mike's customer was havi
I think what is wanted may be something like: eth0 goes to LAN-A
(10.170.0.0/16) while eth1 to to LAN-B (10.171.0.0/16). But both LANs have
their own separate gateway which connects to the world-wide Internet. So the
customer wants be be able to use either eth0 or eth1 when the destination is on
A system can only have one default interface. But it should only be falling
back to default when one of the more specific routes have not been met.
So if I have a system like this:

Mike,

I'm asking this question on the behalf of a customer:
I have this set up fine as far as VM is concerned, and have eth0 and eth1
defined on Linux (RHEL 5.5).
My problem is that the networks defined by eth0 and eth1 have different
gateway addresses, but when both interfaces are brought up, the defaul

Making the virtual machine bigger is probably making things worse.
With real memory that constrained,
The highest priority swap should always be VDISK (not real disk).
Save the real disk for a small contingency (with the lowest priority) in
case you run out of both MEM and VDISK swap.

FYI - the problem we were having with the boot.findself script had to do
with upper/lower case matching issues when the script interrogated the
sles11 parameter files searching for the source and destination server names
and ip addresses. So, the script worked fine once we matched the cases to

the script does have the "sync" command executing after the copy with "dd"

Thanks Berry, yes it did crash with all swap space used. We doubled the memory

Perhaps you can look at the threads for the application. We have a very
small apache that is configured to have only a few childs and threads
within the web server. Granted, it can't service as much threads
simultaneously but the server doesn't abend due to memory problems. So

I'll look into it. So far cpu has only been about 45%.
