autoloader can't auto-switch the media
anybody could give me some suggestion ?
my english is not very good .sorry for any complicated words.
I am using DP5 realize ORACLE online backup with 200G ultrium tape in autoloader .The daily session is working fine.
while,the problem is ,everytime ,when a media in backup pool been write to the end(almost 330G in usage display) , the DP5.1
report error
message,and then quit the job.it wont auto-switch the media in the same pool,while the other media in the pool is fine.

i have change medias so many times . and last week , HP engineer said autoloader's driver maybe have some problem .then
autoloader's driver has been changed . while the problem still appear.
In DP5.1 ,i am using /dev/rmt/1mn as the driver,and autochanger is /dev/rac/c8t0d0. all the driver and autochanger has been
pass the testing stage in OS Driver configuration manual.it seems that when a media write to the end ,DP5.1 haven't
acknowlege it and havn't autochange the media in the pool.
some testing stage about the driver like this :

the SCSI adapter is c8xx---SCSI C1010 Ultra160 Wide LVD ,which direct connect to autoloader . i am using SCTL OS driver for
autoloader. i am not sure if c8xx must use tape2 driver? in the manual ,only talk about driver configuration which direct
connnect to c7xx interface card.

Re: autoloader can't auto-switch the media
i am back again.
there r new autoloader firmware issue :
"The drive now responds correctly when End of Tape (EOT) is reached to prevent any issues if write commands continue to be sent from the host. "
i am not sure if its the reason to my problem.
my autoloader version info list below.
Product ID : Ultrium 1-SCSI
Drive Technology : LTO
Mech. Serial Number : HU73H00575
Firmware Rev : E30P/OEM18
Product ID : ThinStor AutoLdr
Model Name : Tape Autoloader 1/8
* Internal Serial Number : MXH3J02375
Drive Technology : LTO
Firmware Rev : H33r
which the newest version is E33P and H43r.
any other suggestion ?
thanks
Mark
