pxe
       - signals this is pxe imaging
         mandatory parameter
      
      factory
       - print special [FACTORY_...] messages for use by factory. 
         optional parameter.
      
      stit
       - signals to force reimage even if installation exists on the machine
         optional parameter
      
      updfrm
       - check hardware and firmware versions. Update firmware where applicable.
         optional parameter.

      kerver=<kernel_version>
         overwrite default kernel. By defaut installing kernel version depends
         on hardware type (system product name). List of kernels and hardware
         dependencies defined in the "kernel_ver" line at the very top of
         makeImageMedia.sh script.

      dualboot=<yes|no>
         overwtire default dual boot behaviour. It's only applicable for the
         db node. By default dual boot feature (installing Linux image and
         prereserving space for Solaris) depends on hardware type (system
         product name). By default X4170 M2 and X4800 (G5) servers have dual
         boot.
      
      dhcp
       - dhcp is optional parameter and should NOT be given with eth0 option
         If given, dhcp is used to obtain the initial dhcp address instead of
         requiring to pass the eth0 information.
    
      ethX=<ip>:<netmask>:<gateway>
       - ethX is optional parameter. Do NOT give with dhcp above.
       - where X is one of 0,1,2,3 on Sun and 0 on HP machines
         If both dchp and ethX are absent imaging will enter
         interactive mode and ask for Ethernet ip, netmask and
         gateway information
      
      sk=<nfsip>:<nfs_share>
       - sk is mandatory parameter for the PXE boot. MUST
         use IP address not the hostname for NFS server.
         nfs_share is the full path to directory where the 3 files from
         PXE directory are available
      
      logpath=[nfsip:]<full path to writeable nfs share>
       - logpath is optional parameter
         If given it will copy the imaging, zero and first boots logs to the
         writable nfs share location in single tar bzip2 file <serial_num>.tbz.
         The serial_num is the serial number of the system obtained as
           dmidecode -s system-serial-number
     
      ----------------------------------------------- 
      Development ONLY options NOT for use in Factory
      -----------------------------------------------
      
      reboot-on-success
       - Do not wait for operator to power off machine on successful image, just
         reboot. Useful for mass unattended imaging using preconf option.
         DO NOT use in factory process.
         optional parameter
      
      multiprof
       - Image the node as multi profile enabled
         This parameter is optional
         NOTE: Do NOT build the images with -multiprof to makeImageMedia.sh
               If you do that image can only be used to do multi profile nodes.
      
      nodisktests
       - do not run disktests at zero boot. They take 6-14 hours!
         This parameter is optional
      
      notests=<group for validations to be skipped, e.g. diskgroup>
       - Skips all validations with given vldgroup name. For example, if
         diskgroup is given as the group name, then each validation with
         vldgroup set to diskgroup will be skipped. diskgroup today includes
         disktests, calibration and diskhealth. This is one more way to skip
         disktests in addition to the nodisktests option.
         This parameter is optional
      
      preconf=[<preconf_nfsip>:]<full path name of preconf_file on nfs server>
       - preconf is optional parameter
         The nfsip MUST be IP address of the NFS server not its hostname
         The preconf_nfsip can be same or different than the nfsip in sk 
         option, allowing the preloaded configuration file to reside on different
         subtree or entirely different nfs server from that of the imaging bits
         on the nfsip nfs server.

如果不需要双引导启动，设置dualboot=no
