The RO-Flag is a temporar flag, which is set during mount. NetWorker can mount a volume RO (for recovery) or RW (for backup).

The flag is set during the mount and not persitant.

To avoid NetWorker writing to a volume you should set it to full.

but it isn't supposed that read-only mode on a volume prevents networker in using that volume for backup?

i did this on purpose so networker couldn't use both tapes of the pool...

simply: no.

It is a common misunderstanding. This option is really dynamic option during mount.

Ok, so how do i prevent networker from using a specific tape from the pool i configured?

I read that you said to mark the tape full, how do i do this from the networker console?

Well, I guess we cannot do this from the console. It will have to be done using the "nsrmm" command.

nsrmm -o full Vloume_name

HTH,

Yep, not possible from NMM.

A read only tape is a read only tape.  Now if there is a drive ordering issue then a read only tape will be written to since it is a software flag..   Easiest fix is use the hard write protect tab on the back of the tape.

Auto media management - Enabling this attribute allows automated media management for volumes loaded into the device. This includes automatic mounting of NetWorker volumes loaded into the device, automatic labeling of 'blank' volumes loaded into the device, and automatic recycling of eligible volumes loaded into the device. Any volume without a NetWorker label is considered to be blank. For jukebox devices the value of this attribute is inherited from the Jukebox resource.

Auto Media Management is useful for the following situations: -

1. Automatic labelling of scratch or blank volumes into a poll required for a backup.

2. Labelling volumes which are recyclable from one pool into another (if recycle to/from pools is set).

Without Auto Media Management set you cannot do the above.

ok, thank you guys!
