其实它就是一个linux的系统,The /ddvar directory contains Data Domain System core and log files。如果真要备份,可以参考这段话,但我不确认linux的那些命令是否可以完整执行,毕竟它是改良过的。

这个晓得。

经常ssh登录到设备上,简单检查。哈哈。三脚猫。

Re: Data Domain D860 和D890 设备的维护

跳至解决方案

big_leiborn_chen给的重启步骤没错,我这里再次补充两个内容:一个是因为ddvar的信息保存,你可以在关机前收集下系统的配置信息以便以后确认;另一个是关于如何在关机前关闭DD的服务。

下面是第一部分:

Procedure

1. Record the system passphrase. After the headswap, you must reenter this passphrase.

2. Send an autosupport email message to yourself. This message records key system configuration features.

# autosupport send username@yourcompany.com

3. Configure your terminal emulation program to record the session.

4. For a system enabled with DD Extended Retention software (formerly known as Data Domain Archiver), ensure there is no data movement.

# archive data-movement status

# archive data-movement stop

5. Check if space reclamation is running, and if so, suspend it.

# archive space-reclamation status

# archive space-reclamation suspend

6. If used, record the VTL configuration:

# vtl port show summary

# vtl port show hardware

# vtl port option show

# vtl show config

# vtl option show all

7. If either VTL or DDBoost-over-FC is present, record the scsitarget configuration:

# scsitarget group show detailed

# scsitarget endpoint show detailed

# scsitarget initiator show detailed

# scsitarget transport option show all

8. Record the replication configuration:

# replication show config

9. If used, record the NFS and DD Boost configurations.

Although it should not be necessary to manually reconfigure NFS or DD Boost, it is recommended that you record those configuration settings. When you run these commands before and after the controller upgrade, the output should be the same.

# nfs show clients

# net hosts show

# net show hardware

# ddboost show user-name

# ddboost storage-unit show

# ddboost fc status

# ddboost fc dfc-server-name show

# ddboost fc group show list

10.If used, record the CIFS configuration and share definitions:

# cifs share show

# cifs show config

11.Record the file system configuration:

# disk show state

# disk status

# disk show hardware

# system show ports

# disk multipath status

# filesys show space

# enclosure show topology

# mtree retention-lock status mtree mtree-path

# filesys encryption show

# snapshot list mtree mtree-path

12.Record the file system configuration (for systems with DD Extended Retention software option):

# storage show all

# filesys archive unit list all

# archive show config

# archive data-movement policy show

13.Record external network card configuration including card slot, card vendor and model, speed, and number of ports:

# system show hardware

# system show port

# net show hardware

14.Record network services on the controller including failover, aggregation, VLANs, and IP aliases:

# net show settings

# net show config

下面是第二部分,关于停止服务:

1. For a Data Domain system with the Extended Retention software option, ensure there is no data-movement or space-reclamation running.

# archive data-movement status

# archive data-movement stop

# archive space-reclamation status

# archive space-reclamation suspend

2. Check for any active CIFS client connections and stop them. To check for CIFS activity,

enter:

# cifs show active

3. If there are active CIFS clients, disconnect them and disable CIFS by running:

# cifs disable

4. Disable VTL:

a. Determine whether VTL is enabled. To determine if VTL is enabled, enter:

# vtl status

b. If VTL is enabled, disable VTL:

# vtl disable

5. If SCSI Target is enabled (scsitarget status), disable SCSI Target:

# scsitarget disable

6. Determine whether there are NFS connections and unmount the file systems on the remote systems. To identify the remote systems that have mounted the Data Domain storage, enter:

# nfs show active

7. Use the umount command on those remote systems to dismount the NFS file systems.

8. If there are DD Boost connections, stop the backup applications on the connected systems. To identify those systems, enter:

# ddboost show connections

9. Determine whether replication is enabled, and disable replication if it is enabled.

a. To check replication status, enter:

# replication status

b. If replication is enabled, disable it. Enter:

# replication disable all

c. Verify replication is disabled on all contexts. Enter:

# replication status

Note

Do not proceed until all replication contexts are disabled. This may take up to 15 minutes.

10.Verify there is no traffic on the Ethernet NICs. Enter:

# iostat 2

Run for approximately 60 seconds before exiting.

11.A reboot is recommended. This ensures all hardware is in working order.

# system reboot

哦是的,在检查没有备份数据写入,关闭系统前,先停止服务是推荐的更保险的做法。

有空可以切磋切磋,这东西既是体力活,也是技术活,时间点把控、风险控制、回退等都得切合紧密。
