Here is an update, I've isolated where the cciss errors are thrown:
I decided to not install the hp/compaq smartstart cd, but I did attempt to enable the st[0-9] devices:
[root@vz1 ~]# cat /etc/init.d/tape_st
#!/bin/sh
#
# chkconfig: 2345 91 1
# description: Creates the st[0-9] devices for sequential access devices and
# medium changer devices on the cciss block device
#
for x in /proc/driver/cciss/cciss[0-9]*
do
echo "engage scsi" > $x
done
[root@vz1 ~]# chmod 755 /etc/init.d/tape_st
[root@vz1 ~]# chkconfig --add tape_st
Once I did this and rebooted the system, I see the following in /var/log/messages:
Feb 17 15:13:55 vz1 kernel: cciss0: No device changes detected.

As an extra validation, I disabled the tape_st init script:
[root@vz1 ~]# chkconfig --level 12345 tape_st off
[root@vz1 ~]# chkconfig --list|grep tape_st
tape_st 0:off 1:off 2:off 3:off 4:off 5:off 6:off
I then rebooted the system to see if /var/log/messages repeats the errors, it does not.
I then manually started the tape_st service:
[root@vz1 ~]# service tape_st start
/var/log/messages then shows the following:
Feb 17 15:26:21 vz1 kernel: cciss0: No device changes detected.

I then rebooted into the CentOS 4.4 kernel to see if I could reproduce the output there. I am able to.
I've come to the conclusion that the cciss driver bundled with the linux kernal is not the best driver available for the device. The HP driver is provided as an rpm ( http://h18023.www1.hp.com/support/files/server/us/download/2 5360.html) but only supports a limited number of kernels. Attempting to install the rpm returns the following errors:

I'm out of ideas at this point as to the best solution to this predicament. I am open to ideas.
