-comment comment

A comment that is associated with the disk pool.

-dp disk_pool_name

The name of the disk pool. Use the same name that you used when you configured the disk volumes.

-dvlist filename

The name of the file that contains the information about the volumes for the disk pool.

-hwm high_watermark

The default is 98%.

-lwm low_watermark

The Low water mark is a threshold at which NetBackup stops image cleanup.

The Low water mark setting cannot be greater than or equal to the High water mark setting.

The default is 80%.

-M primary_server

The name of the primary server.

-max_io_streams n

Select this option to limit the number of read and write streams (that is, jobs) for each volume in the disk pool. A job may read backup images or write backup images. By default, there is no limit.

When the limit is reached, NetBackup chooses another volume, if available. If not available, NetBackup queues jobs until a volume is available.

Too many jobs that read and write data may degrade disk performance because of disk thrashing. (Disk thrashing is when the read and write heads move between the cylinders excessively as they seek the data for competing jobs.)

Fewer streams may improve throughput, which may increase the number of jobs that complete in a specific time period.

A starting point is to divide the Maximum concurrent jobs of all of the storage units by the number of volumes in the disk pool.

-reason "string"

The reason that you create the disk pool.

-storage_servers hostname

The name of each storage server that has a file system mount on the storage. Specify all NetBackup media servers that are storage servers for this disk pool.

-stype server_type

For AdvancedDisk with encryption, use AdvancedDisk_crypt, otherwise use AdvancedDisk.
