Legato Backup Server DR SOP <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

  

Legato备份服务器系统瘫痪而需要恢复时

 

一． 从本地或异地获得灾难备份磁带

二． 安装备份服务器操作系统并配置网络（包括与磁带库的连接）

  安装操作系统时 我们必须清楚 backup server shbs1 的以下一些信息 :

 

OS 版本信息 : SUNOS 5.8

Partition 信息 : /dev/dsk/c0t0d0s0   à    /          <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />4.88G       0  --  3544

           /dev/dsk/c0t0d0s1   à    /usr       4.88G    3545  --  7089

           /dev/dsk/c0t0d0s3   à    swap      3.91G    7090  --  9925

           /dev/dsk/c0t1d0s4   à   /nsr_index    20.24G   9926  --  24619

                    /dev/dsk/c0t1d0s2   à   /nsr         33.9G       0  --  24619

三． 安装 Legato 服务器端软件，配置存储设备，装载灾难备份磁带；

1.         安装 backup server 上 emulex HBA 卡的 driver 驱动程式

2.         安装 Qlogic SCISI 卡的 driver 和 patch

3.         安装 LEGATO Networker package

 

# cd /cdrom/networker_vol_1/solaris
# pkgadd -d .

The following packages are available:
  1  LGTOclnt     NetWorker for Solaris (Backup/Recover) Client

4. 配置存储设备

  Legato Networker 提供了一个识别系统中的 SCSI 设备的命令，使用该命令可以判断 Legato Networker 是否能够正确识别我们所挂接的磁带设备

      为了使 Legato Networker 能自动地管理磁带库设备，我们需要将配置我们的磁带库设备到 Legato Networker 中，下面是我们在备份服务器上面做的一个例子。

     
Shbs1:/home#[1] jbconfig

         1) Configure an AlphaStor/SmartMedia Jukebox.

         2) Configure an Autodetected SCSI Jukebox.

         3) Configure an Autodetected NDMP SCSI Jukebox.

         4) Configure an SJI Jukebox.

         5) Configure an STL Silo.

 

What kind of Jukebox are you configuring? [1] 2

Installing 'Standard SCSI Jukebox' jukebox - scsidev@4.0.0.

^M

What name do you want to assign to this jukebox device? HP5052

Turn NetWorker auto-cleaning on (yes / no) [yes]? yes

 

The following drive(s) can be auto-configured in this jukebox:

 3> sdlt320 @ 4.3.0 ==> /dev/rmt/3cbn

The 3 drive(s) that cannot be auto-configured will be addressed in a moment,

 but first:

Do you want to configure any of the detected drives as shared or NDMP

drives or otherwise manually change their configuration? (yes / no) [no] yes

 

Is (any path of) any drive intended for NDMP use? (yes / no) [no] yes

Is any drive going to have more than one path defined? (yes / no) [no] yes

^M

You will be prompted for multiple paths for each drive.

Pressing <Enter> on a null default advances to the next drive.

 

 

Please enter the device path information in one of the following formats:

 

        /dev/rmt/1cbn --for local path or

        host:device-path --for remote node or

        host:drive-letter:directory path --for Windows disk file

 

   After you have entered a device path, you will be prompted for an NDMP

user name for that path's host. If this device path is not an NDMP device,

press the enter key to advance to the next device path.  For NDMP devices,

you need to enter the user name and password the first time we encounter

that NDMP host. Pressing the enter key for the NDMP user name for any

subsequent device path on the same host will set the user name and password

to those defined the first time. You will not be prompted for the password

in such a case.

 

Drive  1, element 480

Device path 1 ? /dev/rmt/0cbn

     Enter NDMP user name for host 'bj50'?

Device path 2 ?

     Enter NDMP user name for host 'bjna01'? root

Enter NDMP password (characters will not be echoed): *******

Device path 3 ?

     Enter NDMP user name for host 'bjna02'? root

Enter NDMP password (characters will not be echoed): ********

Device path 4 ?

     Enter NDMP user name for host 'bjna03'? root

Enter NDMP password (characters will not be echoed): *******

Device path 5 ?

 

Drive  2, element 481

Device path 1 ? /dev/rmt/1cbn

     Enter NDMP user name for host 'bj50'?

Device path 2 ?

     Enter NDMP user name for host 'bjna01'? root

Device path 3 ?

     Enter NDMP user name for host 'bjna02'? root

Device path 4 ?

     Enter NDMP user name for host 'bjna03'? root

Device path 5 ?

 

Drive  3, element 482, system name = /dev/rmt/3cbn,

       local bus / target / lun value = 4/3/0,

           model sdlt320

Device path 1 ? [/dev/rmt/3cbn] /dev/rmt/3cbn

     Enter NDMP user name for host 'bj50'?

Device path 2 ?

 

Drive  4, element 483

Device path 1 ? /dev/rmt/2cbn

     Enter NDMP user name for host 'bj50'?

Device path 2 ?

 

Only model sdlt320 drives have been detected.

Are all drives in this jukebox of the same model?  (yes / no) [ yes]

 

 

Jukebox has been added successfully^M

 

The following configuration options have been set:

 

   > Jukebox description to the control port and model.

   > Autochanger control port to the port at which we found it.

   > Networker managed tape autocleaning on.

   > At least one drive was defined with multiple paths.  All such drives are

     defined with a hardware identification as well as a path value to avoid

     confusion by uniquely identifying the drive.  The hardware identification

     for all drives which have one is always 'autochanger_name - Drive #' where

     "autochanger_name" is the name you gave to the autochanger that was

     just defined, and the # symbol is the drive numer.

   > Barcode reading to on.

   > Volume labels that match the barcodes.

   > Slot intended to hold cleaning cartridge to 50.  Please insure that a

     cleaning cartridge is in that slot

   > Number of times we will use a new cleaning cartridge o 5.

   > Cleaning interval for the tape drives to 6 months.

 

You can review and change the characteristics of the autochanger and its

associated devices using nwadmin.

 

Would you like to configure another jukebox? (yes/no) [ no ]

If your resource files were lost, they are now recovered in the 'res.R'
directory.  Copy or move them to the 'res' directory, after you have shut
down the service.  Then restart the service.

Otherwise, just restart the service.

If the on-line index for happy was lost, it can be recovered using
the nsrck command.

 
由于恢复的目录为 /nsr/res.R 要将原目录 /nsr/res 备份，将 /nsr/res.R 该为 /nsr/res

#cd /etc/init.d/

#./networker stop

#mv /nsr/res   /nsr/res.bak

#mv /nsr/res.R  /nsr/res

#./networker start 

 

3． Reset 带库

 

#nsrjb –vHE

 

五． 触动恢复功能，恢复最近一次的全备份数据

   

#nsrck  -L7

 

六． 完成事故报告

对事故作记录，总结事故发生原因，避免产生同样的问题。
