Scanner on saveset with multiple tapes
Hi Guys,
Quick question. If i've got a saveset that spans multiple tapes, do i need to scan those tapes one at a time (sequentially), as the scanner requests the next tape? Or if i have 3 tape drives, can i scan the ssid on all three tapes concurrently?
No Events found!

Hi,
According to the documentation, this needs to done sequentially, but I think if you are using NetWorker version 7.6.2, it should work concurrently also. If you are on that version, you should test it.

Hi Babak,
You will need indeed to scan all the tapes which contains the save set.
If you do a query either with mminfo or in NMC, you will see that the save set has flags, in each volume such as:
hb
mb
tb
These flags means:
h: header
m: middle
t: tail
b: browsable
Basically this indicates which tape contains the header of the save set (this tape has to be scanned in first place), middle is that this tape contains part of the spawned save set, and tail is the tape which contains the last part of the save set.
Once you start to scan the first tape (header) NetWorker, once is done with the part of the save set, will prompt you to mount the following tape (middle) so it can continue with the scanner. Once the middle part of the save set has been scanned in then it will ask you to mount the last tape (tail).
Please let us know if you need any further informaiton.
Thank you.
Carlos.

I believe for spaning save sets sequential scan is required.
