Creating a logical storage unit (LSU)
A logical storage unit (LSU) is a logical container within a storage domain on the SpanFS cluster that NetBackup uses to store and retrieve backup data. Each LSU represents a logical grouping of storage that NetBackup consumes when creating disk pools, which are then used to create storage units.
You must create an LSU before it can be selected when creating a disk pool.
Before you create an LSU, ensure that:
A storage domain already exists on the SpanFS cluster.
The SpanFS storage server is configured in NetBackup.
You have planned whether the LSU requires immutability (WORM).
Note:
Storage domains define the data layout characteristics such as deduplication, compression, encryption, and fault tolerance.
See Creating a storage domain using the NetBackup web UI.
To create a logical storage unit (LSU)
- In the NetBackup web UI, on the left, click Storage > Disk storage, select the Disk pools tab, and then click Add.
- On the Disk pool options page, click Change and select SpanFS as the storage server type.
- Click Select and then click Next.
- On the Volumes page, click Add.
- Configure the LSU details:
Volume name: Enter a name for the LSU.
Storage domain: Select the storage domain in which the LSU must be created.
Click Add to add a new storage domain.
WORM (optional): Enable WORM if the LSU requires immutable storage. Select one of the following:
Enterprise: Allows retention settings to be modified by authorized administrators.
Compliance: Enforces strict, non modifiable retention to meet regulatory requirements.
- Click Add.
The logical storage unit is created and becomes available for selection during disk pool creation.
