[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
ExaBR 1.2.6 (b12259)

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