Hi Gerhard, stop/start processing of the tape drive - the disk pool does not stream the data fast enough to cause a continues flow of data - hence when there has been a stop in the flow of data there needs to be some kind of re-positioning - to continue writing where the last bit of data was written. Normal behavior.
Cheers Christo ---------------------------------------------------------------------- Hello, I observed some strange behaviour of a 3590-E1A tape drive. During a migrate operation from a disk pool to a sequential pool I watched the operator panel. There I could see that the device after a write operation did a locate followed by a read and then resumed writing. I observed this behaviour several times. Is there an explanation for this? I run TSM 4.1.2 on AIX 4.3.3 Best regards Gerhard ---- Gerhard Rentschler email: [EMAIL PROTECTED] Manager Central Servers & Services Regional Computing Center tel: ++49/711/6855806 University of Stuttgart fax: ++49/711/682357 Allmandring 30a D 70550 Stuttgart Germany ______________________________________________ "The information contained in this communication is confidential and may be legally privileged.
