Specify the following parameters when you configure the Dell EMC XtremIO SAN plug-in:
Table: Dell EMC XtremIO SAN plug-in configuration parameters
Snapshot Manager for Data Center configuration parameter | Description |
|---|---|
Plugin ID | Provide a name for the plugin. |
FQDN/ IP Address | The array's IP address, in IPV4 / FQDN format. |
User name | A user account that has permissions to perform snapshot operations on the Dell EMC XtremIO SAN array. |
Password | Provide a password to the user account. |
The following screen is displayed when you configure the plug-in using the NetBackup Administration Console:
The following considerations and limitations are applicable:
All the snapshot which are taken for any volume are read-only mode. There is a new re-purpose copy cloned from the volume which is used for data backup.
The re-purpose clone copy is only done in the export operation not in the create snapshot directly.
The repurpose clone copy is deleted based on the scheduled deport from NetBackup or manually triggering the expire operation. This is a thin provisioned type copy.
The limit for any volume name is 128 characters on the array. So, a user can have the maximum length of volume name is 128 - (23 (NB<unique_21digit_number>) - 9 (Repurpose) - 2 (Dot notations)) = 94. It is a strict requirement to limit the volume name to 94 characters for a successful snapshot creation.
It is strictly advised, not to write the data to repurpose copy created by NetBackup through manual mapping it on to the host server. User created re-purpose copies are considered as an individual volume in NetBackup. But changing the copies starting with volume_name.NB<unique_21digit_number>.repurpose is strictly not recommended.
Don't refresh the repurpose copy, as it changes the data from the parent volume and backup, and restore operations.
For example: If you have a volume V1 and a snapshot is triggered for the same then the protection copy occurs with the V1.NB<unique_21digit_number> format and in the export operation, a repurpose copy occurs with the name V1.NB<unique_21digit_number>.repurpose.
