Description of problem:
Installer will not detect megaraid or Mylex cards during the install
process. This system installs fine under RedHat 7.1 but fails to install
or upgrade under 7.2.
1 PII 350 CPU
1 GB ECC Registered Ram
HP Netraid 1si (megaraid)
External Compaq Raid Box 4 x ultra2 9 Gig Compaq HD's
1 4 gig Seagate ultrawide HD on the integrated Scsi controller (adaptec)
1 Quantum DLT7000 Tape drive on integrated scsi controller (adaptec)
1 50x IDE CD rom master on secondary channel
2 3Com 905B nic Cards
1 Riva128 AGP videocard (8megs)
Also tried with a Mylex Raid card (model number not known) neither card
was detected by the RedHat 7.2 Installer, the HP Netraid card is detected
and functions perfectly under RedHat 7.1. I did not try the mylex card
under RedHat 7.1, But I can if you need that info.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Insert RedHat CD
2. Power Up and start installation
Actual Results: Megaraid and Mylex Cards are not detected and drivers are
not installed during installation. The adaptec on-board controller is the
only storage controller detected
Expected Results: Raid controllers should be detected and drivers
I have an HP Netraid adapter that is detected, but no logical drives are found.
This happens during a fresh install of redhat 7.2 or attempting to upgrade
Redhat 7.1 to Redhat 7.2. The latest driver from HP 1.15 does not appear to
work with Redhat 7.2 Also, the latest kernel update for redhat 7.1 (2.4.9-12),
after it is installed, my system will not boot the kernel. I receive a kernel
panic, no init found. This same kernel panic happened with kernel update
(2.4.9-6). This did not happen with kernel update (2.4.3-12).
I'm seeing the same problem here with a NetRaid 1si card in an HP NetServer
LPr. Since all disks are driven by this card (two internal 18.2GB drives in a
mirror set), installation fails as soon as anaconda notices that there's
nothing to install to. I'm working on fashioning an updated driver disk for
this, but would obviously rather see an updated driver disk from Red Hat. ;-)
dkl, do we have the hardware necessary to test this?
I have an extra netraid3 card with is just a 3 port version of the 1si card. I
would be willing to loan it if I can get a gurantee that it will be returned
because it is a $2,000 card.
I've successfully created a driver disk which permits one to boot a Red Hat
Linux 7.2 system on systems with NetRaid controllers (at least, with a NetRaid
1si, which is my test system). It is available from:
The module has been compiled from the Matt Domsch's MegaRaid 1.18 source
It Works For Me(tm). :-)
I tried this driver disk. System updated perfectly without a hicth... Ok RedHat
guys how did this slip through ?
Anyone feel like making one of those disks for the Mylex DAC960 ?
The installer hangs on loading its driver with redhat 7.1 and 7.2.
What to do, what to do ?
ok, I tested on an HP Netraid 1M adapter (supports 64 bit via firmware
update). Redhat 7.2 seen the controller and Raid set. The UPGRADE from rh 7.1
to 7.2 went fine. The reboot however was messy. Kernel Panic with try passing
init= to the kernel messages. My solution was to use rescue mode with the
driver disk megaraid.img (see above notes). This allowed me to mount the
drives. I then took the source code megaraid-1.18-tar.gz (see notes above)and
compiled the modules on another machine running a default install of redhat
7.2. I then took the newly compiled modules and copied them
to /lib/modules/2.4.7-10/kernel/drivers/scsi. I made backup copies of the
original files before I copied over them. I then made a backup copy
of /boot/initrd-2.4.7-10.img, then I deleted /boot/initrd-2.4.7-10.img. I then
issued the command /sbin/mkinitrd /boot/initrd-2.4.7-10.img 2.4.7-10 . I then
rebooted and ALL WAS WELL. The server came up just fine. Just a side note, I
originally installed with GRUB, but changed to LILO. And I did convert from
ext2 to ext3. I'm going to try a kernel update next. I expect it to fail with
the same kernel panic. I now know that I'll have to replace the megaraid.c and
megaraid.h files in my source tree and rebuild a custom kernel probably for
now. I hope this has helped anyone out there using a Mylex or Netraid Adapter.
Arjan -- any ideas as to what the problem is here?
Most likely the HP Megaraid firmware is outdated; we've seen problems in this
How could this be the firmware ? Using a driver disk works and the install
works perfectly on 7.1.
the 1.18 driver has specific workarounds for certain versions of HP firmware....
I understand that the 1.18 driver has workarounds, but this works under Redhat
7.1 flawless. Installs and runs fine no driver disk needed.
The bios and firmware levels of the machine are currently the most recent
revisions from HP. Also when I performed my kernel update from 2.4.7-10 to
2.4.9-13, I built the new kernel from source using the megaraid.c and
megaraid.h from the 1.18 source. The new kernel booted just fine after the
I can confirm that I'm running the latest BIOS and firmware from HP for the 1si
controller (BIOS 2.03, firmware 2.05). You can download the software bundles
for the entire netRAID lineup from HP's website at:
For the record: I'd upgraded the firmware before trying to install Red Hat
Linux 7.2. None of the 7.2 kernels ship with a working megaraid module for
netRAID controllers. I'm a little concerned about the one I built from 1.18, as
well; during bootup, it shows:
megaraid: [??? : ??? ] detected 1 logical drives
megaraid: channel is raid.
scsi0 : AMI MegaRAID ??? 254 commands 16 targets 1 chans 8 luns
The "???" above are goofy characters (smiley faces, etc). Doesn't exactly
inspire confidence. ;-)
When trying out the RH-supplied 2.4.9-13, the system boots, displays a
recognition of the controller just as above (goofy characters and all), and
hangs upon trying to mount the root filesystem, occasionally giving back scsi
This is probably a good time to also mention that there's another bugzilla
entry, #47221, which appears to be a duplicate of this bug. Perhaps the
component of this bug ought to be kernel as well, since this really boils down
to the megaraid module as shipped with 2.4.7-10 not recognizing the netRAID
controller, and 2.4.9-13 doing the "wrong thing" with it. ;-)
I would agree that it is a kernel issue. The one thing I don't think I
mentioned is that I did not use the Red Hat RPM for the kernel 2.4.9-13. I
installed the RPM sources and compiled my own kernel. I did however replace
the redhat megaraid.c/megaraid.h sources files with those in the 1.18 driver
listed above. This allows the card to be properly detected, and eliminates the
weird characters when loading the megaraid driver for my system when booting.
I started receiving the weird characters in Red Hat 7.1 kernel 2.4.3-12, and if
I tried to go above that kernel version, the megaraid driver failed to load.
I've made a new kernel RPM with the .18 megaraid driver:
Tried this kernel out. A couple of things:
. Mounting the root filesystem fails with the same scsi timeout I was seeing
with my own kernel. So, for kicks, I started poking around the netRAID
configuration menus (CTRL-M at bootup, just like MegaRAID controllers). There's
a setting under Options|Adapter called "Emulation", which toggles between I2O
and MASS STORAGE emulation. Changing from I2O to MASS STORAGE allowed me to
boot. I'm assuming that's because of the next point...
. There's a bunch of new I2O stuff in this kernel that wasn't in 2.4.7-10. ;-)
Is that possibly what's causing a bad interaction here?
. A quick search on google for "emulation I2O MASS STORAGE" after finding out
that that particular setting worked came up with the following from SuSE:
Basically, they suggest making the same change I just found by trial and
error. ;-) Doh.
Hopefully, this is enough information to help anyone else suffering from this.
Just thought that I'd say the I2O option has been disabled on my card. It has
always been set to mass storage mode. This is the DEFAULT setting for my
Anyway the 2.4.9-21 kernel has megaraid 1.18...
As to the I2O.. yes that part is f*cked. The adapter *almost* succeeds in
emulating an i2o device ;(
The new Skipjack beta 2 has the same problem on HP LC 2000 with NetRaid-1Si
It does not find hard drives on which to make partiotions and installation
stops. The same is with RedHat 7.2.
RedHat 7.1 installs without problems.
This is specific to NetRaid-1Si controller.
If we change the controller to NetRaid-1M, then the installation works ok,
at least with RedHat 7.2.
Other people have the same problem at
1) did you disable I2O on the card ?
2) do you have the most recent firmware ?
1) Yes, I2O is disabled.
2) Firmware is latest (BIOS 2.03, firmware 2.05)
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
