          [root@el02node01 bin]# ./exabr h

          ExaBR   1.2.6 (b12259)


          Usage: exabr <command> <targets> [options]


          General options:

            --version                Display the exabr version

            --help                   Display this usage help and exit


          Targets:

            Targets can be specified by listing the comma-separated IPs or hostnames or by using one of the predefined targets: 

            all-ib (all Infiniband switches), all-mgmt (all management (Cisco) switches), all-cn (all compute nodes and their ILOMs), 

            all-cn-iloms (all compute nodes ILOMS), all-sn (all storage nodes and their ILOMs), all-sn-iloms (all storage ILOMs),

            all-hw (all the hardware components), control-stack, user-vm (zfs snapshot)

            or all-itemized-vms (all user-vservers listed in the configuration file)


          Common options:

            --repository, -r         path to the backup repository (any path, usually a mount to a NFS share)

                                     (EXABR_REPO environment variable can be also used instead)

          Commands:


          init - initialize the exabr configuration file. Uses ECU data or the configuration of the given compute-node to obtain hostnames of different rack components

            exabr -r <repository-path> init <first-compute-node>

            

          init-ssh, remove-ssh - establish or remove SSH public key authentication

            exabr -r <repository-path> init-ssh <targets>

            exabr -r <repository-path> remove-ssh <targets>

            

          backup - back up the target to the backup repository

            exabr -r <repository-path> backup <targets> [--noprompt]

            exabr -r <repository-path> backup <compute-nodes> [--noprompt] [--exclude-paths </path>,..] [--include-paths </path>,..]

            exabr -r <repository-path> backup <itemized-vms> [--noprompt] [--exclude-paths </path>,..] [--include-paths </path>,..]

            Options:

              --noprompt, -n         never prompts for password, and skips the target instead if public key authentication has not been 

                                     established (via init-ssh command)

              --exclude-paths        comma-separated list of directories or files that should not be included in the backup

              --include-paths        comma-separated exclusive list of directories and/or files to be backed up

              --timeout              timeout value in seconds to wait for the backup to complete. Default is 2700 seconds.


              

          restore - restore the target from the backup repository 

            exabr -r <repository-path> restore <targets> [-b <backup-name>]

            exabr -r <repository-path> restore <compute-nodes> [-b <backup-name>] [--exclude-paths </path>,..] [--include-paths </path>,..]

            exabr -r <repository-path> restore <itemized-vms> [-b <backup-name>] [--exclude-paths </path>,..] [--include-paths </path>,..]

            exabr -r <repository-path> restore user-vm [-b <snapshot-name>] --vm <vm-name-or-uuid>

            exabr -r <repository-path> restore control-stack [-b <snapshot-name]

            Options:

              --backup, -b           the name of the specific backup to be restored. If option is not given, the latest backup is used. 

                                     the backup name is shown in brackets by 'list' command.

              --exclude-paths        comma-separated list of directories or files that should not be restored from the backup

              --include-paths        comma-separated exclusive list of directories and/or files to be restored

              --vm                   name or uuid of the vm to restore from the named zfs snapshot. Restores entire disk image

              --timeout              timeout value in seconds to wait for the restore to complete. Default is 2700 seconds.

              

          stop, start - stops or starts control stack VMs

            exabr -r <repository-path> stop control-stack

            exabr -r <repository-path> start control-stack

            

          list - list the content of the backup repository 

            exabr -r <repository-path> list <targets> [--verbose]

            Options:

              --verbose, -v          display more details

              

          ib-register - when the hardware component has been replaced and has a new Infiniband identity, register it with the Infiniband fabric

            exabr -r <repository-path> ib-register <targets> [--dry-run]

            Options:

              --dry-run              display the commands that would be run without performing them.

            

          configure - configure and/or check the ECU networking settings for a re-imaged compute node

            exabr -r <repository-path> configure <target-compute-node>

            

          control-unregister - unregister a compute-node from OVMM and from EMOC even if it is not reachable, or missing

            exabr -r <repository-path> control-unregister <target-compute-node>

            

          control-register - register a live compute-node with OVMM and with EMOC

            exabr -r <repository-path> control-register <target-compute-node>


          ERROR: Invalid arguments. Two arguments expected: <command> <targets>



          以上为命令的帮助.

          1.首先进行初始化

          ./exabr init 10.135.1623.200      <= first node of exalogic


          2.对配置文件进行编辑

          编辑/exalogic-lcdata/backups/exabr.config文件


          3.对ib结点进行备份


          [root@el02node01 bin]# ./exabr backup all-ib

          4.对计算结点进行备份

          [root@el02node01 bin]# ./exabr backup all-cn


          5.对存储结点进行备份

          [root@el02node01 bin]# ./exabr backup all-sn


          6.对思科交换机备份

          [root@el02node01 bin]# ./exabr backup all-mgmt 

          7.备份硬件信息

          [root@el02node01 bin]# ./exabr backup all-hw



          以上的备份文件默认存放在 /exalogic-lcdata 下,如需要指定目录,可使用 -r 参数
