I have some stateful nodes in my cluster that are also attached to SAN
storage. I have found that when installing the node,
the install process accesses the SAN drives and corrupts them. I have the
following in the *.tmpl (which came with the xcat install)
file which I thought would eliminate this, but I have not been successful
in my testing:
%pre
#!/bin/sh
# This will remove the loaded HBA modules from the kernel
#modprobe mptsas
#modprobe mptscsih
#modprobe mptbase
#modprobe scsi_transport_sas
remove_qla(){
for i in $(lsmod | grep qla | awk .{print $1.}); do
echo Will remove: $i >> /dev/tty1
rmmod $i
sleep 1
done
}
remove_lpfc(){
for i in $(lsmod | grep lpfc | awk .{print $1.}); do
echo Will remove: $i >> /dev/tty1
rmmod $i
sleep 1
done
}
remove_qla
sleep 2
remove_qla
remove_lpfc
echo "All qla modules removed"
sleep 10
