NetBackup™ 重复数据删除指南

运行到新的 MSDP 直接云层服务器的迁移

在继续安装和配置新的 MSDP 直接云层服务器这一过程之前，建议您设置日志记录。如果安装期间出现任何问题，日志可帮助您诊断迁移期间的任何潜在错误。各项建议如下：

要运行迁移，请转到 MSDP 直接云层服务器上的命令提示符，然后运行：

/usr/openv/netbackup/bin/admincmd/nbdecommission -migrate_cloudcatalyst

选择要迁移的 Cloud Catalyst 存储服务器，然后按 nbdecommission 实用程序的提示输入信息。

以下是迁移期间所显示内容的示例：

# /usr/openv/netbackup/bin/admincmd/nbdecommission -migrate_cloudcatalyst
MSDP storage server to use for migrated CloudCatalyst:  myserver.test.com

Generating list of configured CloudCatalyst storage servers.
This may take a few minutes for some environments, please wait.

Cloud Storage Server Cloud Bucket CloudCatalyst Server Storage Server Type
1) amazon.com         my-bucket    myserver.test.com   PureDisk_amazon_rawd

Enter line number of CloudCatalyst server to migrate: 1

MSDP KMS encryption is enabled for amazon.com.
Please confirm that CloudCatalyst was configured using 
KMSKeyGroupName amazon.com:testkey

Continue? (y/n) [n]: y

Enter new disk volume name for migrated CloudCatalyst server: newdv
Enter new disk pool name for migrated CloudCatalyst server: newdp
Enter cloud account username or access key:  AAAABBBBBCCCCCDDDDD
Enter cloud account password or 
secret access key: aaaabbbbccccddddeeeeffffggg

You want to migrate amazon.com (bucket my-bucket) to
newmsdpserver.test.com (volume newdv, pool newdp).
Is that correct? (y/n) [n]: y

To fully decommission myserver.test.com after 
CloudCatalyst migration is complete,run the 
following command on the master server:
/usr/openv/netbackup/bin/admincmd/nbdecommission 
-oldserver myserver.test.com

Administrative Pause set for machine myserver.test.com

Migrating CloudCatalyst will include moving the images to server 
newmsdpserver.test.com deleting the old disk pool, storage unit, and 
storage server, deactivating policies that reference the old storage 
unit, and restarting MSDP on server newmsdpserver.test.com.

Before proceeding further, please make sure that no jobs are running on
media server myserver.test.com or media server newmsdpserver.test.com.
This command may not be able to migrate CloudCatalyst
with active jobs on either of those servers.

To avoid potential data loss caused by conflicts between the 
old CloudCatalyst server and the migrated MSDP server, stop the 
NetBackup services on myserver.test.com if they are running.

It is recommended to make one or both of the following changes 
on myserver.test.com to prevent future data loss caused by 
inadvertently starting NetBackup services.
1) Rename /usr/openv/esfs/bin/vxesfsd to /usr/openv/esfs/bin/vxesfsd.off
2) Change "ReadOnly" to "1" in the esfs.json configuration file
See the documentation for more information about esfs.json.

It is also recommended to perform a catalog cleanup and backup prior 
to migration so that the catalog can be restored to its original 
state in the event that migration is not completed.

Continue? (y/n) [n]: y

Successfully cloned storage server: amazon.com to: 
newmsdpserver.test.com_newdv

Storage server newmsdpserver.test.com has been successfully updated

The next step is to list the objects in the cloud and migrate 
the MSDP catalog. The duration of this step depends on how much data 
was uploaded by CloudCatalyst.
It may take several hours or longer, so please be patient.

You may reduce the duration by not migrating the 
CloudCatalyst image sharing information if you are certain that 
you do not use the image sharing feature.

Do you wish to skip migrating CloudCatalyst image 
sharing information? (y/n) [n]:

监控 nbdecommission 命令的输出是否有错误。要监控其中是否有活动和潜在错误的其他日志位于 storage_path/log/ 目录中。您应监控 ocsd_storage 日志，并监控 spad 和 spoold 日志是否有任何 cacontrol 命令问题。

如果遇到错误且该错误可更正，您可以使用 nbdecommission 命令输出中所注明的 start_with 选项从该点继续迁移。如果您对此错误有任何问题，请联系 Veritas 支持，然后再继续迁移。

在迁移期间，迁移运行时会显示多个提示。必要时，您可以使用命令行选项来回答这些提示。Veritas 建议使用交互式提示，因为与使用命令行选项相比，它可使迁移更易于使用，而且更不容易出错。如果您选择使用命令行，则选项记录在 NetBackup 命令参考指南中。

在迁移过程中，大多数提示都不需要解释，而且提示的数量和类型会变化。提示的数量和类型取决于以下内容：

表：迁移提示讨论有关几个提示的附加信息。
