NetBackup™ 重複排除ガイド

新しい MSDP ダイレクトクラウド階層サーバーへの移行の実行

新しい MSDP ダイレクトクラウド階層サーバーのインストールと構成のプロセスを続行する前に、ログの設定をお勧めします。インストール中に問題が発生した場合、ログは移行中に発生する可能性のあるエラーの診断に役立ちます。推奨項目を次に示します。

移行を実行するには、MSDP ダイレクトクラウド階層サーバーでコマンドプロンプトに移動して、次を実行します。

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

移行する Cloud Catalyst ストレージサーバーを選択し、nbdecommission ユーティリティのプロンプトに従って情報を入力します。

移行中に表示される可能性がある例を次に示します。

# /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]:

nbdecommission コマンドの出力でエラーを監視します。アクティビティと潜在的なエラーを監視するためのその他のログは、storage_path/log/ ディレクトリにあります。cacontrol コマンドの問題については、ocsd_storage、spad、spoold ログを監視してください。

エラーが発生して、そのエラーを修正できた場合は、nbdecommission コマンドの出力に示されるとおり start_with オプションを使用して、その時点から移行を再開できます。エラーについて質問がある場合は、移行を再開する前に Veritas のサポートにお問い合わせください。

移行を実行すると、移行中に複数のプロンプトが表示されます。必要に応じて、コマンドラインオプションを使用してこれらのプロンプトに対する回答を入力できます。Veritas では、コマンドラインオプションを使用した場合よりも移行が簡単になりエラーが発生しにくくなるため、対話形式のプロンプトを使用するようお勧めします。コマンドラインを使用する場合は、『NetBackup コマンドリファレンスガイド』にオプションが記載されています。

移行プロセス中のプロンプトの多くは自明であり、プロンプトの数と種類は変化する場合があります。プロンプトの数と種類は次によって異なります。

表: 移行のプロンプト では、いくつかのプロンプトに関する追加情報について説明します。

No MSDP storage server found on 
myserver.test.com.

Please create the MSDP storage server 
before running this utility.
