What driver/software are needed for Linux RHES 5.1 to connect to NetApp SAN

Hi

We've laid the SAN fibre cables to connect the RHES 5.1 server's Emulex ports to
NetApp SAN switch.

I found following 2 software in our folder which I believe my predecessor probably
used :
1)FCP Linux Host Attach Kit 1.0.zip (abt 482kb)
- is this the driver that needs to be installed on the Linux server so that
Linux can communicate with the Netapp SAN filer?

2)FCP Linux Host Utils 3.0.zip (about 510kb)
- is this the tools needed on Linux so that it can view/manipulate the SAN
partitions?

Any guess is most welcome

Any other things I need? The two RHES Linux server will probably be
clustered (done by someone else, not me) for Oracle RAC. The SAN
disk partitons will be accessible by both the Linux Oracle RAC servers.

Multipathing configuration?

Thanks Robo & Meyers,

Hi Meyers,
> 2.6 kernel has native Emulex drivers
Are you referring to Redhat's kernel & how do you get the 2.6 version (from 'uname -a').
How do I verify Emulex drivers is present : from "rpm -qa | grep -i lcfc" I saw an rpm
listed - is this it?

Hi

A couple more questions:

After creating these & configured /etc/multipath.conf, what's the device files
that our DBAs should be using for setting up Oracle RAC ASM raw devices?

Is it /dev/mapper/mpathx or /dev/mpath/mpathx ?

Oracle RAC clustering will be used so is Linux clustering still needed?

Thanks for the LED - it appeared that on a working Linux server that's currently
accessing the SAN's storage, a green LED is On & steady (no blinking) while
the orange/amber light blinks twice in a row, pause for abt a second, & blinks
again twice & pause a second & ...

In this working server, there are 2 fibre cables connected & they blinks at the
same time but the new server which also have 2 fibre cables, both the green
LEDs are steady while their amber/orange LEDs takes turn to blink

That's mighty weird. Do you know what model cards they are?
