Excessive tape unmounts
I recently was having ECC errors on my tape drive. Those are gone due to new drives. I noticed that I get an escessive amount of unmounts with my tape drive while waiting for ESX to stream the data to the drive. That causes the tape to unmount....
I'm running windows server 2k8R2 64-bit with a MSL4048 with 2 LTO 5 drives.
I have mulitplexing turned on to speed up backups already. This works great on full backups but on daily's when the amount is small, the tape unmounts and mounts many times while proccessing our backup policies.
I'm using Windows-Flashbackup on ESX4.1 and 5.1. I have media multiplexing turned on to 2, and only daily's do this.
Anybody know if I can set no rewind in Windows?
I have already tried setting the Media unmount delay to 1800 seconds and it seems to have no effect.
