RHEL 5 and MSA1000

mkisow — Tue, 07 Jul 2009 10:09:36 GMT

I have an MSA1000 connected to a BL680c blade server inside of a C7000 chassis. I am using Emulex LPe1105 mezzanine cards to attach to the MSA1000.

Using tools like scsi_info, hp_rescan and adapter_info I can see the MSA1000 however I cannot fdisk /dev/sda -l the device.

When I go into the MSA1000's presentation settings I noticed that both fibers were active, I have unplugged one pair and am not even able to see the MSA through the tools listed above now.

Any help given is appreciated.

Shalom,

With qlogic cards this is easy.

If you actually intend to mount filesystems on the MSA1000 at boot time you will need to create a new system ram disk including the emulex driver.

This is after installing the emulex drivers:
Make required changes to /etc/modprobe.conf

cd /boot
mv initrd-....img to initrd-....img.orig

mkinitrd

mkinitrd initrd-2.6.9-42.0.3.ELsmp.img 2.6.9-42.0.3.ELsmp

Kernel version is something you will need to change.

When ever I attempt to install the emulex driver package I am told that the driver already exists, it "should" be using it.

Shalom,

run lsmod, lets see what drivers are loaded.

Now that I think of that, my procedure was required on RHEL 4, update 3. The driver may well be installed in version 5 RHEL.

Here is the output you requested, it appears that it is not installed. I go to install the Emulex package and it complains about a library and gcc not being installed, however both are installed.
