NetBackup nbdevconfig command options for AdvancedDisk disk pools
Table: nbdevconfig command options for AdvancedDisk disk pools shows the options that you can use when you use the nbdevconfig command to configure an AdvancedDisk disk pool
Table: nbdevconfig command options for AdvancedDisk disk pools
A comment that is associated with the disk pool.
The name of the disk pool. Use the same name that you used when you configured the disk volumes.
The name of the file that contains the information about the volumes for the disk pool.
The high_watermark setting is a threshold that triggers the following actions:
The default is 98%.
Theis a threshold at which NetBackup stops image cleanup.
Thesetting cannot be greater than or equal to the setting.
The default is 80%.
The name of the master server.
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 theof all of the storage units by the number of volumes in the disk pool.
The reason that you create the disk pool.
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.
For AdvancedDisk with encryption, use AdvancedDisk_crypt, otherwise use AdvancedDisk.
