About fast-tape positioning (locate-block) on Solaris

Applies to AIT, DLT, Exabyte, DTF, and half-inch tape drives.

To position a tape to a specific block, NetBackup supports the SCSI locate-block command. It requires the NetBackup sg driver.

NetBackup uses the locate-block command by default.

Veritas recommends that you do not disable locate-block positioning. If you need to disable it, execute the following command:

touch /usr/openv/volmgr/database/NO_LOCATEBLOCK

If locate-block positioning is disabled, NetBackup uses the forward-space-file/record method.
