[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)
