Replacing the drive
HP StorageWorks DAT removable drives can be removed and replaced without powering down the
tape array. However you should be aware of the following:
• If all drives in the tape array are powered up when the system is turned on, the host will be
aware of those drives. You can remove any of those drives and replace it with another drive as
long as there is no activity on the bus.
• Do not remove or add drives to a bus that already has drives connected and running, for
example backing up or restoring data. Wait until there is no activity on the bus before removing
or adding drives.
• If a drive is not powered up or you place a drive in an empty slot after the system has been
powered up, the system will have to be reset before the host will recognize the drive.
• The SCSI IDs are controlled by the tape array, not by the drives themselves, so if you remove a
drive and replace it with another the ID will not change.
1. Pull the extraction lever of the drive that you want to replace so that it is in the out position.
