上传preconf.csv到/xd目录

[root@xifenfei xd]# ll preconf.csv 
-rw-r--r--  1 root root 2133 Mar 14 18:14 preconf.csv

然后重启dhcp,xinetd,nfs服务,重启需要恢复的xd的db and cell节点,验证结果如下

    注意在RHEL5中在/usr/lib/syslinux/pxelinux.0

  2. 惜分飞 说:

    参数说明

          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
