This is the result of the MPT Fusion driver rebuilding the initrd file and modifying elilo.conf when the it is installed. The following is a comparison of the elilo.conf file contents before and after the driver installation:
Before
prompt timeout=20 default=linux relocatable
After
prompt timeout=20 default=HP
#Corresponds to kernel
#(previously, default=linux) relocatable
#The following entry was added by Proliant HBA install script
#in package
label=HP
#Corresponds to kernel
The default variable is changed to HP that corresponds to the Xen kernel and a new image stanza is inserted into the file. This new stanza is missing a line, which causes the server hang during reboot.
To avoid the system hangs during reboot, you must modify the file /etc/elilo.conf manually after the MPT Fusion driver is installed and before rebooting the server using the following steps:
1.Edit /etc/elilo.conf.
2.Add the following line immediately after the line,
The file should now look like:
prompt timeout=20 default=HP
#Corresponds to kernel
#(previously, default=linux) relocatable
#The following entry was added by Proliant HBA install script
#in package
