Drives Showing Missing Paths
Couple of drives showing missing paths , I have deleted and Re-configured the drives after verifying correct serial.no. of the drives but there is no Luck.
Still drives are showing missing paths.....
tpautoconf seeing 12 drives means that you have 3 drives not responding to scsi-commands.
Check Windows Event Viewer System log for errors.
You can also try to delete all tape drives in Windows Device Manager and then rescan. See if all devices come back and check System log for errors.
Use HBA tool (e.g. SanSurfer for QLogic HBA) to see if all devices can be seen and if Persistent Binding is in place.
PS:
15 tape drives on a single server seems excessive...
Even the most powerful server will battle to stream more than 3 drives.
