[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>

以上為命令的幫助．

1.首先進行初始化

./exabr init 10.135.1623.200      <= first node of exalogic

2.對配置文件進行編輯

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

3.對ib結點進行備份

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