Re: repost: RedHat kernel 2.4.20 on PE 1750

Hi,
back in the days when we used FW-1 (4.1, Redhat 7.0 and 2.2x kernel)
those kernel modules from checkpoint loaded in every kernel I tried.
We used then a newer stock 2.2x kernel and it worked rock solid.

As you have now gone away from using the standard kernel I'd try to go
with something newer perhaps?
Either a newer stock kernel or use the latest Redhat 9 kernel and get 
rid of the nptl patches.
In 2.4.25 there is the megaraid2 driver already included.

PE750 + SUSE SLES 8

Does anyone know what the "certification status" of SLES8 is on the PE750?

It installs ok, and the network works after I either install the latest 
intel drivers or update to the SP3 kernel.

I have a customer who wants a "supported" solution, but doesn't want RH 
(some sort of app support issue, the app comes from Germany, so no real 
surprise).

Any guidance  on  current  / future plans for support would be appreciated.

Any  known issues with SUSE (may end up with SUSE 9 pro) would also be 
appreciated.

ta
Bart.

rhel 3.0 es swap partition over 2.0 gb

What are the consequences of a swap partition over 2.0 gb.
I know that Redhat says it each partion should be < 2.0.
Is this just wasted space, or can problems occur.

qla2200, EMC symmetric and Dell Poweredge 2650

Hi list,

I've got a quick query concerning connecting a Dell Poweredge 2650 running
RHEL3 - basic kernel install - with 2 x qla220 FC to an EMC Symmetrix.
The modules for the qla2200 have been loaded and are visible to the OS but
i've checked on the Qlogic website and it states that the qla2200f is
supported by EMC but not the qla2200 - has anybody had experience using the
qla2200? Does it work?
Apologies if this is deemed off topic.

Thanks,

Simon

Poweredge 1650 RAID problems

We got a Dell Poweredge 1650 off eBay a few days ago
and we have severe problems with it. I think it's
hardware problem but I don't see any hardware-specific
list, so I'm trying to ask here.

First, all attempts to install Debian Woody were
unsucessful, because installer wasn't able to
recognize any disks (there are 3 36GB Seagates). 
We tried to boot from regular 3.0r2 and
http://oregonstate.edu/~kveton/debian/debian-dell-2.4.25.iso
and also
http://linux.dell.com/files/debian/bootbf2.4.19-ac4.iso.

If RAID controler is enabled in BIOS, a message
"Warning: Embedded RAID firmware is not present" shows
up during boot.
Attempt to install a new RAID firmware was
unsuccessful. Update program didn't detect any RAID
controllers. 
We also updated BIOS to the newest revision available
from Dell website.
We replaced a ROMB card with another one but it didn't
help. The only thing that changed is that now we can
see NIC's MAC addresses in BIOS. Earlier MAC address
fields read "Not Present". It seems very strange to
me... what a raid card has to do with NICs ?

Finally, we removed ROMB card completly but of course
nothing changed - disks are not visible.

At least for vanilla versions of linux (can't speak for rhel), space
beyond 2GB for an individual swap partition is wasted.  I haven't
observed anything breaking as a result of it; it's just unused.

If you want more than 2GB swap space, create & format several 2GB
partitions or swapfiles and configure /etc/fstab.

e.g.:

[root <at> server root]# cat /etc/fstab
 <snip>
/dev/sdb1          swap         swap    defaults        0 0
/dev/sdb2          swap         swap    defaults        0 0
/disk1/swapfiles/0 swap         swap    defaults        0 0
/disk1/swapfiles/1 swap         swap    defaults        0 0
/disk1/swapfiles/2 swap         swap    defaults        0 0

[root <at> server root]# df -h /dev/md1
Filesystem            Size  Used Avail Use% Mounted on
/dev/sdb1            1011M  500M  460M  53%

[root <at> server root]# df -h /dev/md7
Filesystem            Size  Used Avail Use% Mounted on
/dev/sdb2            1011M  500M  460M  53%

Hello,

We haven't PERC controller but we tried to reinstall driver for AIC

We can't try sysrq because its remote server.

Yes.

Echo service doesn't respond during system crash.

Once we can login by SSH but logging proces hangs after entering
password.
Usualy we cannot conect to SSH.

No. This resources are not exhausted.

DVD CD-RW Suggestions

Any recommendations for favorite DVD CD-RW burners?    We are going to invest in a portable device that we can
use to burn snapshot images of our Dell boxes running RH Linux or Windows.  

Any suggestions?
