Write enabled?

[Titann]

Hi All,

Im having a problem where the write enabled on some of the storage nodes change from a "yes" to a "no" and i have no idea what causes it..

And it happens from time to time... it changed on all the the tape devices for a particular storage node last night, causing the back not to run at all..

Version 7.1.3

Thanks in advance

That sounds wrong. The attribute "Write enabled" is per mounted volume so unmounting and mount another volume should clear that. Is it read-only or enabled attributes that changes as well?

Devices becoming not enabled due to crossing the threshold of consecutive errors I've seen but not that the "write enabled" has changed for some other reason then above. I would have a look at the daemon.log file and see if there are any traces of A switch.

You can always set the RAP Monitor to enable and check rap.log after this happens again. Maybe there is someone changing it manually? In that case, that will be registered in the rap.log file.

Hi Rif123..

Checked the rap.log.. nothing there. the read-only stays unchanged. when i checked the backup never ran. all the write-enabled for that storage node were set to "no

From field help:

Write enabled - This attribute indicates whether writing can be done to the mounted volume. This only applies to the currently mounted volume.

So, mounting/unmounting volumes will change the value. So this should not be your issue. Try to run a manual backup and see what happens.

Hi Rif123,

If i understand correctly what you are saying is that when a tape gets mounted the value should change from "no" to "yes" for the write enabled.

I will do some testing as i found inconsistancies in this.

some of the values remains on a "no" so i figure when a tape mounts it doesnt write to it.

Yep, that is what I am saying. When a tape becomes full, it should also change status.
