CCISS Driver (for DL360) useable with 2.4.27-xen0 ?

CCISS Driver (for DL360) useable with 2.4.27-xen0 ?

[zyta2002]

Hi @ all...

I'm tryin to compile a 2.4.27-xen0 kernel on a RH3 AS Server running on a Compaq Proliant DL360.
This Server has a builtin Compaq Smart Array Controller

HP CISS Driver (v 2.4.47.RH1)
cciss: Device 0xb178 has been found at bus 0 dev 4 func 0
      blocks= 71122560 block_size= 512
      heads= 255, sectors= 32, cylinders= 8716 RAID 1(0+1)

The problem:
If I load the config using

make oldconfig ARCH=xen
or
make menuconfig ARCH=xen

I can't see the SmartArray drivers in the kernel options. Does this mean, that the Cpq CCISS driver isn't supported to work under XEN ?

Should I add the CPQ driver manually to the XEN kernel ?

thx in advice
Andy

CCISS Problem [SOLVED] !!

But another problem is coming up.

I'm not able to increase the maxmem from a domain.

Example:
my domain has a maxmem from e.g. 64MB
Using the balloon driver, I'm able to decrease/increase the memory from 0-64MB without a problem.

Now I've tried to increase the maxmem to 128M using
xm maxmem MyDomain 128

But 'xm list' reports still 64M.

Then I've tested to decrese the maxmem value:

xm maxmem MyDomain 30M

This works... using the balloon command, I'm not able to increase over 30M of Mem.

But... when I wan't increase the maxmem from 30M to 64M again, this results in "nothing" useful.
maxmem is still 30M :/

btw: Is the HIGHMEM kernel a problem ?

[root@pl370_node3 xen-src]# grep HIGH /boot/config-2.4.27-xen0
# CONFIG_NOHIGHMEM is not set
CONFIG_HIGHMEM4G=y
CONFIG_HIGHMEM=y
CONFIG_HIGHIO=y

another potential useful info:

[root@myhost xen-src]# xm info
system                 : Linux
host                   : myhost
release                : 2.4.27-xen0
version                : #5 Wed Nov 17 13:16:29 CET 2004
machine                : i686
cores                  : 1
hyperthreads_per_core  : 2
cpu_mhz                : 2799
memory                 : 1023
free_memory            : 849

Greetz & Thx
btw: gr8 piece of software !!! =)

I think there's a maxmem kernel parameter that allows you to specify
the largest amount of memory you ever want to give the
domain. Otherwise Linux will assume that it's initial memory
allocation is the maximum for all time.
