Does anyone run any hot standby systems on Linux 390?
Is the data (if any) migrated and health checked by your own code or is there some
software that I need to be made aware of?
Thanks

I'm running ntpdate (and logging the output) every five minutes in lieu of
ntpd for timekeeping. On the same (and only) guest :

There are certainly sites using the Linux-HA clustering code on

We have 8 paths to each chpid on the mainframe dasd.
And I/O subsytem.
SAN is network and is fiber.
I had wondered if the paths had helped swing the stats.

How many paths to SAN switch? How many host adapators on the STK? How
many ranks are the SCSI disks split over? The HA is the real limiting
factor here. A maxed out ESS (i.e. all possible CHPIDs HA in use to
disks split) is a capable of 250 MB/s (read) and about half that for
write.
Jim,
With SLES8 you have to pay separate license/maint. fees for 31-bit and 64-bit
versions. So with SLES9 you do not?
Also, others (at IBM) had lead me to believe SLES9 would be 64-bit only but 31-bit
apps could run under it.
In either case, the pricing sounds better. 64-bit only sounds fine too
Hi again!
I sorted out the last problem around PROFILE TCPIP and it turns out it was an

that line of enquiry. Anyway I've now got another problem.

I'm confused by your 'host adapter' questions. The SAN is an EMC device.
The STK mainframe dasd is ESCON attached to the z800. 3 LPARS share 3 RVA's.
Now that we are using snapshot we have 6 paths to each chpid. When we were testing
we had 8.
I'm pretty SAN illierate but I can ask the storage
Hi Nigel,
I ran into the same problem when installing SLES 8 from my PC, using SMB. I
was told that there are some problems using SMB or FTP to a PC with this
type of install. I was able to get past this problem by doing a NFS
install, which worked much better!

Do you have the on demand timer patch enabled? If so, turn it off, and
see if this changes.

Hi
Neale has sent me cpint-2.2.0, and I've uploaded it to the web site. Please
note that this is for Linux 2.6 systems _only_. Neale says that he'll be
coming out with a 2.3.0 version fairly soon to work better with sysfs and
probably change the diag0 driver into creating readable entries in sysfs.
Perhaps I should have added that different installation methods have
different storage requirements. You may want to verify with the readme
that 256MB is enough for a VNC install. I use 256MB for a ssh install.
You can certainly step down the virtual machine size after install.
On Mon,
I got not enough space errors when I was having I/O erros reading it. Check
the console to see if you have any bad messages there.

I don't see the cpint_load command in the 2.1.0 cpint,
just hcp, monstat, and mongen.
Will the 2.2 version work with 31 and 64 bit.
