sorry guys to open this one but i am desperate finding answers
i have a backup on a recylable tape with no index. i do not know which version was the tape written. now i want to scan the tape for indexes because i need only few files from the tape and do not have enough storage for saveset recovery. the backupr esides on 7 tapes.
is this the right approach with the scanner command ran from the storage node?
if so. how do i know which was the first tape? does it even matter which tape i mount to start the scan? shall i mount or just load? is there a difference?
checked mminfo command reference guide which says h should be head t - tail and m - middle. so the first one will be the first tape.
Correct. Also, make sure to make nsrmm -o notrecyclable -S ssid for your ssid before you start scanning it. If you delete it, then scanner will read it too and dates will be reset as the save has happened on the time when scanner was done.
First tape will have ssflags (or sumflags, don't remember now) with header mark which you can see from mminfo. Actually, with mminfo you can easily see in which sequence data was written.
Scanner command looks good. Obviously, if this is expired tape/saveset you must change that first with nsrmm and only then do scanner (even if you have index backup still somewhere nsrck -L7 -t time client name would be faster).
i checked all the volumes containing the backup and they have all these flags which lead me to the question how do i know which was the first one...
client created ssid ssflags fl clientname 13/01/2007 2175344289 vrEF hE clientname 13/01/2007 2175344289 vrEF tE clientname 14/01/2007 2628415495 vrEF mE clientname 13/01/2007 2175344289 vrEF mE clientname 13/01/2007 2175344289 vrEF mE clientname 13/01/2007 2175344289 vrEF mE clientname 13/01/2007 2175344289 vrEF mE clientname 13/01/2007 2175344289 vrEF mE
the saveset resides on 7 tapes. i have a tape reading failure du to hardware problem after 3rd tape. do i have to start form begining or can run it for the rest ?
