Configure an AdvancedDisk disk pool
How you configure an AdvancedDisk disk pool depends on the type, as follows:
|
type |
You must use the nbdevconfig command if you configured an type of storage server. NetBackup encrypts the backup data on the type of disk pool. See “To configure an AdvancedDisk disk pool by using the nbdevconfig command”. NetBackup cannot discover Windows Common Internet File System (CIFS) disk volumes. For CIFS storage, you must use the UNC notation to specify the volumes. See About AdvancedDisk file system requirements. See Configure a CIFS disk volume for AdvancedDisk encryption. |

type |
Cohesity recommends that you use the disk pool configuration wizard to configure the type of disk pool. After you configure a storage server, the wizard prompts you to create a disk pool. Therefore, you may not need to invoke the disk pool wizard separately. See “To configure an AdvancedDisk disk pool by using the wizard”. NetBackup cannot discover Windows Common Internet File System (CIFS) disk volumes. For CIFS storage, you must use the UNC notation to specify the volumes. |
Cohesity recommends that disk volume and disk pool names be unique across your enterprise.
You must first configure storage servers.
To configure an AdvancedDisk disk pool by using the wizard
- On the left, select Storage > Disk storage.
- Click Next.
Configure the following:
To select a storage server, select the Change button.
Enter the Disk pool name that you want to use.
Make any other configuration changes that you want for the disk pool.
- Select the volumes to use for the disk pool. NetBackup does not filter out common file system mount points, such as
/and/usr. Therefore, carefully choose the volumes to include in a disk pool. - On the Review page, verify the selections. To save the changes and add the disk pool, select Finish.
- After the disk pool is created, configure an AdvancedDisk storage unit.
To configure an AdvancedDisk disk pool by using the nbdevconfig command
- On the host that has a file system mount on the storage, discover the volumes that are available and write them to a text file. If you intend to use multiple hosts to read to and write from the storage, use any of the hosts. The following is the NetBackup command to use, depending on your operating system:
UNIX: /usr/openv/netbackup/bin/admincmd/nbdevconfig -previewdv -storage_server hostname -stype server_type > filename
Windows: install_path\NetBackup\bin\admincmd\nbdevconfig -previewdv -storage_server hostname -stype server_type > filename
The following describe the options:
-storage_server hostname
The name of the NetBackup media server that has a file system mount on the storage.
-stype server_type
For AdvancedDisk with encryption, use AdvancedDisk_crypt, otherwise use AdvancedDisk.
> filename
The name of the file into which to write the volume information. Cohesity recommends that you use a name that describes its purpose.
- Copy the file that you created in step 1 to the primary server.
- In a text editor, delete the line for each volume that you do not want to be in the disk pool. Do not delete the blank line at the end of the file.
Each volume that is listed in the file must be exposed to each AdvancedDisk storage server on the same mount point.
- Configure the disk pool by using the following command, depending on your operating system:
UNIX: /usr/openv/netbackup/bin/admincmd/nbdevconfig -createdp -dp disk_pool_name -stype server_type -storage_servers hostname... -dvlist filename [-reason "string"] [-lwm low_watermark_percent] [-max_io_streams n] [-comment comment] [-M primary_server] [-reason "string"]
Windows: install_path\NetBackup\bin\admincmd\nbdevconfig -createdp -dp disk_pool_name -stype server_type -storage_servers hostname... -dvlist filename [-reason "string"] [-lwm low_watermark_percent] [-max_io_streams n] [-comment comment] [-M primary_server] [-reason "string"]
The nbdevconfig command options are described in a different topic.
See NetBackup nbdevconfig command options for AdvancedDisk disk pools.
