rename DRAC from CLI OS

For some reason, a number of our physical hosts do not have their DRACs configured correctly, or according to our standard.

I wrote this script to clean them up.

#!/bin/bash
# Desc:  This horribly assembled bit of scripting is intended to configure the DRAC using
#        a few basic fundamental configuration variables.
#        The end result should be a host DRAC that is reachable via
#        <hostname>.mgmt.company.com

# A few helpful commands to review:
# /opt/dell/srvadmin/bin/idracadm7 getconfig -g cfgLanNetworking
# /opt/dell/srvadmin/bin/idracadm config -g cfgLanNetworking -o cfgDNSRacName `hostname -s`

yum -y install srvadmin-all srvadmin-idrac7
ls /opt/dell/srvadmin/bin/idracadm && myDRAC="/opt/dell/srvadmin/bin/idracadm"
ls /opt/dell/srvadmin/bin/idracadm7 && myDRAC="/opt/dell/srvadmin/bin/idracadm7"

if [ -z $myDRAC ]
then
  echo "ERROR: idracadm[7] was not found"
  echo "       yum -y install srvadmin-all srvadmin-idrac7 "
  exit 9
fi


# THIS >MAY< NEED TO BE UPDATED BASED ON LOCATION (GL vs PCW)
