Configuring WORM and DLTWORM support

The following table describes WORM and DLTWORM attributes.

Table 1. WORM/DLTWORM attributes The following table describes WORM and DLTWORM attributes.
Attribute	Description
WORM pools only hold WORM tape	By default, the NetWorker software only allows WORM tapes into WORM pools. Deselecting this option lets you add new (non-WORM) tapes to a WORM pool. This is useful when you need WORM functionality but do not have WORM tapes available.
WORM tapes only in WORM pools	By default, NetWorker only lets you label WORM tapes into WORM pools. Clear this option when: You do not want to separate WORM tapes within WORM pools. A volume is needed to complete a group and a non-WORM tape is unavailable.
WORM capable	This attribute indicates that this drive supports the use of WORM media.
DLTWORM capable	This attribute indicates that this drive can create DLTWORM tapes from a blank tape.
WORM pool	This pool should hold WORM tapes (depending on the setting of “WORM pools only hold WORM tape” in the server).
create DLTWORM	If selected, before the NetWorker software labels a tape in a drive capable of creating DLTWORM volumes, NetWorker will try to convert the tape into a DLTWORM tape. If that conversion fails, the labeling for that tape will fail. If a tape drive in a pool where this attribute is set cannot create DLTWORM tapes, (that is, the tape drive is not a Quantum SDLT600, DLT-S4 or DLT-V4 tape drive, this attribute is simply ignored. Refer to the Quantum web site for information on which tapes can be converted to DLTWORM tapes. Not all firmware revisions for all of these devices support WORM operation. Check the tape drives website to make sure that your drive has up-to-date firmware.

Click OK when finished making the necessary selections.

NOTE:If you attempt to assign a non-WORM capable drive to a WORM pool an error message is generated.
