Disabling device

[Štefan Sakalík]

Hello,
I want to tell udev in RHEL6 _not_ to create a hard drive device in
/dev/ identified by (for example) serial number. I see two problems:
1. AFAIK it is not possible to disable device creation in udev/rules.d/
2. It is not possible to identify device by serial number in udev. When
I run: udevadm info -a -p $(udevadm info -q path -n /dev/sdak)
, it does not show me serial or other identifying information.

I need to get rid of this device because I'm sharing one disk array
between two servers and both of them see all devices in the array.
I want to make sure the two servers are not accessing the drives
simultaneously.

-Stefan

As you are using RHEL6, why not ask for support for this type of
situation from Red Hat? You are paying for the support, might as well
use it :)

Good luck,
