next in thread | raw e-mail | index | archive | help
Just to share my experience with Freebsd5.2 with the
following h/w configs which may help some who are
having the similar problem(s) to resolve.
os: freebsd 5.2
hw: ibm eserver x335 with onboard LSI1030
ext. scsi controller: ibm serveRaid-6m
details:
* the system scsi hdd (36GB) is tied to the LSI1030 scsi controller.
* serverRaid-6m on pci-x slot2, with a set of disk array connected via scsi.
(remember to config the disk array 1st, synchronized them and get them
ready to be used.)
- installation of freebsd 5.2 required to disabled ACPI on boot.
- after installation, remember to choose to disable ACPI on boot permanently
via sysinstall or "set hw.acpi.0.disabled=1" via boot loader prompt.
("set boot_verbose=YES" helps u to debug system booting and h/w detection.)
impt:
freebsd 5.2 is said to be supporting serveRaid-6m, however it is not so with
the newer batch of Adaptec serverRaid-6m cards! because the vendor id and
hardware id hardcoded in ips.h are not updated!)
- with the os setup properly, next is to config the serverRaid-6m. you need to
know how to recompile your kernel and drivers, as the hardcoded IDs for the
serverRaid-6m scsi card needs to be changed.
references:
refer to linux >= 2.5.x kernel sources if u can, and look for the ips.h
header file for the ips driver modules, which is what the serverRaid-6m card
required. file shld be located in the linux kernel src,
{kernel_src}/drivers/scsi/ips.h
while freebsd 5.2 kernel sources,
/usr/src/sys/dev/ips/ips.h
impt:
adaptec serverRaid-6m: VENDOR_ID=9005, DEVICE_ID=0279
ibm serverRaid-6m: VENDOR_ID=1014, DEVICE_ID=0279
- edit /usr/src/sys/dev/ips/ips.h,
---original_code->
#define IPS_VENDOR_ID 0x1014
#define IPS_MORPHEUS_DEVICE_ID 0x01BD
---modified_code->
#define IPS_VENDOR_ID 0x9005
#define IPS_MORPHEUS_DEVICE_ID 0x0279
Then recompile this modified kernel sources and install it.
Refer to the Freebsd Handbook on building & installing new kernel.
If u couldn't do it, then wait for someone to update the kernel,
release a patch for it.
The serverRaid-6m card will be detected and disk array(s) can be used
after that. :-)
Have fun!
regds,
yh
