Smart Array 5i Controller driver for Linux

[Sanjay_23]

H/w: HP DL380

Friends,
I'm installing Sentry Firewall but when booting the OS using the CD & config floppy, I still can not access the local disk of the server.

When I give the #lsmod command, it shows that the CCISS modules is unused. I checked the /var/adm/messages file & it shows that the kernel recognises the HP CISS Driver but still not sure as why I can't see the local drives.
Why the CCISS module is shown as "unused".

Thanks in advance.

Are there logical drives defined and available on the smart array?

While you boot the box, it will output a section for each smart- array starting with the line 'initializing' (with those fake rotors at the end), a count of unites presented, and a prompt for to go on, to set up.
Hit that F8 and view the drives?

You may also want to download the "Array Control Utility' = ACU = cpqacuxe. Then again, if the driver is not active that might not be able to talk.

fwiw,
Hein.

The disk (c0d0) has already got Linux installed.

The process to install the Sentry Firewall is -

1. Boot from the CD.
2. The CD refers to the configuration file from the floppy & reads it.
3. It creates ramdisk partition where it copies all the config. files.

The issue is, I can access the ramdisk etc. But when trying to access the logical disk, I'm in trouble.

Do I need to modify any configuration changes in the floppy or copy any other files in the CD?

Here's the website to the Sentry Firewall webpage - http://www.sentryfirewall.com/ - Any other thoughts?

It sounds like the kernel revision on the CD is a bit old, or stripped so it doesn't have full driver complement.

That being said, 1.5.0-rc15 says it's using a 2.4.27 based kernel, which should have a sufficient enough driver for a '5i', assuming it's compiled in.

You might want to look at the instructions at http://www.sentryfirewall.com/files/HOWTO/sentry-firewall-cd-howto-3.html#ss3.5 for modifying the CD's boot-kernel to try using a newer 'cciss' or something.

[Sanjay_23]

All steps followed from the url & updated the cd accordingly.

The kernel recognises the HP CISS driver & the entry gets into the /var/adm/messages file.

The kernel also identifies the cylinders, sectors etc. of the hard disk but the lsmod still shows the cciss module as "unused"?????

Below are the excerpt from the log files:

I'm afraid I've not used the firewall product, so can't help here. I'd see if there was a Sentry Filweall Mailing list, and ask them if they've witnessed similar behaviour.

Guys,

I found the solution -

The device file has to be created using the following script:
#!/bin/sh
# Script to create device nodes for SMART array controllers
# Usage:
# mkdev.cciss [num controllers] [num log volumes] [num partitions]
#
# With no arguments, the script assumes 1 controller, 16 logical volumes,
# and 16 partitions/volume, which is adequate for most configurations.
#
# If you had 5 controllers and were planning on no more than 4 logical volumes
# each, using a maximum of 8 partitions per volume, you could say:
#
# mkdev.cciss 5 4 8
#
# Of course, this has no real benefit over "mkdev.cciss 5" except that it
# doesn't create so many device nodes in /dev/cciss.

NR_CTLR=${1-1}
NR_VOL=${2-16}
NR_PART=${3-16}

if [ ! -d /dev/cciss ]; then
mkdir -p /dev/cciss
fi

C=0; while [ $C -lt $NR_CTLR ]; do
MAJ=`expr $C + 104`
D=0; while [ $D -lt $NR_VOL ]; do
P=0; while [ $P -lt $NR_PART ]; do
MIN=`expr $D \* 16 + $P`
if [ $P -eq 0 ]; then
mknod /dev/cciss/c${C}d${D} b $MAJ $MIN
else
mknod /dev/cciss/c${C}d${D}p${P} b $MAJ $MIN
fi
P=`expr $P + 1`
done
D=`expr $D + 1`
done
C=`expr $C + 1`
done
